Continued explosions, ash plumes, and ashfall during October 2022-May 2023

Ebeko, located on the N end of Paramushir Island in the Kuril Islands, consists of three summit craters along a SSW-NNE line at the northern end of a complex of five volcanic cones. Eruptions date back to the late 18th century and have been characterized as small-to-moderate explosions from the summit crater, accompanied by intense fumarolic activity. The current eruption period began in June 2022 and has recently consisted of frequent explosions, ash plumes, and thermal activity (BGVN 47:10). This report covers similar activity during October 2022 through May 2023, based on information from the Kamchatka Volcanic Eruptions Response Team (KVERT) and satellite data.

Activity during October consisted of explosive activity, ash plumes, and occasional thermal anomalies. Visual data by volcanologists from Severo-Kurilsk showed explosions producing ash clouds up to 2.1-3 km altitude which drifted E, N, NE, and SE during 1-8, 10, 16, and 18 October. KVERT issued several Volcano Observatory Notices for Aviation (VONA) on 7, 13-15, and 27 October 2022, stating that explosions generated ash plumes that rose to 2.3-4 km altitude and drifted 5 km E, NE, and SE. Ashfall was reported in Severo-Kurilsk (Paramushir Island, about 7 km E) on 7 and 13 October. Satellite data showed a thermal anomaly over the volcano on 15-16 October. Visual data showed ash plumes rising to 2.5-3.6 km altitude on 22, 25-29, and 31 October and moving NE due to constant explosions.

Similar activity continued during November, with explosions, ash plumes, and ashfall occurring. KVERT issued VONAs on 1-2, 4, 6-7, 9, 13, and 16 November that reported explosions and resulting ash plumes that rose to 1.7-3.6 km altitude and drifted 3-5 km SE, ESE, E, and NE. On 1 November ash plumes extended as far as 110 km SE. On 5, 8, 12, and 24-25 November explosions and ash plumes rose to 2-3.1 km altitude and drifted N and E. Ashfall was observed in Severo-Kurilsk on 7 and 16 November. A thermal anomaly was visible during 1-4, 16, and 20 November. Explosions during 26 November rose as high as 2.7 km altitude and drifted NE (figure 45).

Explosions and ash plumes continued to occur in December. During 1-2 and 4 December volcanologists from Severo-Kurilsk observed explosions that sent ash to 1.9-2.5 km altitude and drifted NE and SE (figure 46). VONAs were issued on 5, 9, and 16 December reporting that explosions generated ash plumes rising to 1.9 km, 2.6 km, and 2.4 km altitude and drifted 5 km SE, E, and NE, respectively. A thermal anomaly was visible in satellite imagery on 16 December. On 18 and 27-28 December explosions produced ash plumes that rose to 2.5 km altitude and drifted NE and SE. On 31 December an ash plume rose to 2 km altitude and drifted NE.

Explosions continued during January 2023, based on visual observations by volcanologists from Severo-Kurilsk. During 1-7 January explosions generated ash plumes that rose to 4 km altitude and drifted NE, E, W, and SE. According to VONAs issued by KVERT on 2, 4, 10, and 23 January, explosions produced ash plumes that rose to 2-4 km altitude and drifted 5 km N, NE, E, and ENE; the ash plume that rose to 4 km altitude occurred on 10 January (figure 47). Satellite data showed a thermal anomaly during 3-4, 10, 13, 16, 21, 22, and 31 January. KVERT reported that an ash cloud on 4 January moved 12 km NE. On 6 and 9-11 January explosions sent ash plumes to 4.5 km altitude and drifted W and ESE. On 13 January an ash plume rose to 3 km altitude and drifted SE. During 20-24 January ash plumes from explosions rose to 3.7 km altitude and drifted SE, N, and NE. On 21 January the ash plume drifted as far as 40 km NE. During 28-29 and 31 January and 1 February ash plumes rose to 4 km altitude and drifted NE.

During February, explosions, ash plumes, and ashfall were reported. During 1, 4-5 and 7-8 February explosions generated ash plumes that rose to 4.5 km altitude and drifted E and NE; ashfall was observed on 5 and 8 February. On 6 February an explosion produced an ash plume that rose to 3 km altitude and drifted 7 km E, causing ashfall in Severo-Kurilsk. A thermal anomaly was visible in satellite data on 8, 9, 13, and 21 February. Explosions on 9 and 12-13 February produced ash plumes that rose to 4 km altitude and drifted E and NE; the ash cloud on 12 February extended as far as 45 km E. On 22 February explosions sent ash to 3 km altitude that drifted E. During 24 and 26-27 February ash plumes rose to 4 km altitude and drifted E. On 28 February an explosion sent ash to 2.5-3 km altitude and drifted 5 km E; ashfall was observed in Severo-Kurilsk.

Activity continued during March; visual observations showed that explosions generated ash plumes that rose to 3.6 km altitude on 3, 5-7, and 9-12 March and drifted E, NE, and NW. Thermal anomalies were visible on 10, 13, and 29-30 March in satellite imagery. On 18, 21-23, 26, and 29-30 March explosions produced ash plumes that rose to 2.8 km altitude and drifted NE and E; the ash plumes during 22-23 March extended up to 76 km E. A VONA issued on 21 March reported an explosion that produced an ash plume that rose to 2.8 km altitude and drifted 5 km E. Another VONA issued on 23 March reported that satellite data showed an ash plume rising to 3 km altitude and drifted 14 km E.

Explosions during April continued to generate ash plumes. On 1 and 4 April an ash plume rose to 2.8-3.5 km altitude and drifted SE and NE. A thermal anomaly was visible in satellite imagery during 1-6 April. Satellite data showed ash plumes and clouds rising to 2-3 km altitude and drifting up to 12 km SW and E on 3 and 6 April (figure 48). KVERT issued VONAs on 3, 5, 14, 16 April describing explosions that produced ash plumes rising to 3 km, 3.5 km, 3.5 km, and 3 km altitude and drifting 5 km S, 5 km NE and SE, 72 km NNE, and 5 km NE, respectively. According to satellite data, the resulting ash cloud from the explosion on 14 April was 25 x 7 km in size and drifted 72-104 km NNE during 14-15 April. According to visual data by volcanologists from Severo-Kurilsk explosions sent ash up to 3.5 km altitude that drifted NE and E during 15-16, 22, 25-26, and 29 April.

The explosive eruption continued during May. Explosions during 3-4, 6-7, and 9-10 May generated ash plumes that rose to 4 km altitude and drifted SW and E. Satellite data showed a thermal anomaly on 3, 9, 13-14, and 24 May. During 12-16, 23-25, and 27-28 May ash plumes rose to 3.5 km altitude and drifted in different directions due to explosions. Two VONA notices were issued on 16 and 25 May, describing explosions that generated ash plumes rising to 3 km and 3.5 km altitude, respectively and extending 5 km E. The ash cloud on 25 May drifted 75 km SE.

Thermal activity in the summit crater, occasionally accompanied by ash plumes and ash deposits on the SE and E flanks due to frequent explosions, were visible in infrared and true color satellite images (figure 49).

Ash ejections to 1 km; steaming fissures form

Beginning 14 October, two vents on a sheer wall of the N crater began ejecting fine ash and steam to 300 m above the summit. Pulsations of activity occurred 3 or 4 times a day. Ejections reached 1 km height, with a plume that extended horizontally 10-15 km NE. Fissures that formed on the outer E flank of the crater emitted steam. No seismicity preceded or accompanied the ash-steam ejections. The press reported that ash and gas began to be emitted from the main crater before 2100 on 19 October, and the crater lake was emptied of water. A 1-km-high ash column formed on 27 October and the next day a small amount of ash fell on the town of Severo-Kurilsk (a few kilometers away). No casualties resulted from the eruptions. Additional equipment was installed to monitor the volcano. Variations in gas composition of near-crater fumaroles were observed 4 years ago, and an increase in the temperatures of fumarole emissions has been noted since the October eruption. The press reported that scientists did not rule out the possiblilty of a lahar which could pose a danger to the S part of Severo-Kurilsk.

Explosions continue; minor ashfall

Explosive eruptions began on 14 October, from two of the three vents in the N summit crater. A gas cloud continuously rose 150-250 m while periodic explosions sent ash plumes to heights between 300-400 m and 1,000-1,200 m (table 1). Similar activity continued 14-20 November. A meteorological station in Severo-Kurilsk (6 km S) recorded the explosions.

No seismic precursors to the eruption were recorded and the seismic station of the Inst of Marine Geology & Geophysics, in Severo-Kurilsk, did not detect any earthquakes in the region during the eruption. The same station recorded earthquakes before and during the more distant (but much larger) 1981 eruption of Alaid (40 km NW). Specialists from the IV, Petropavlovsk, are working at the volcano. Air observations were made by the Inst of Marine Geology & Geophysics.

Mild explosions eject ash to 800 m

Mild explosive activity from the NW portion of Ebeko's N crater was reported in August and September. . . . activity from a vent 100 m across and 50 m deep occurred at 1-3-hour intervals. Ash was ejected to 800 m. No juvenile material was found in the tephra. Volcaniclastic bombs (<=0.2 m) were ejected onto the crater slopes within 500 m of the vent. The position of the observers was not known, but the only audible explosion occurred 23 September at 1422.

Fumarolic activity from 1989 eruption site; sulfur emissions

On 12 and 13 August, members of an SVE team climbed the volcano and observed fumarolic activity concentrated mainly in the NW vent, the site of the 1989 eruption, and inside the S crater. Small hot water lakes (50-60°C) were present at ~950-1,000 m elev on the outer SE slope of the S crater, ~150 m below the rim. A small cold crescent-shaped lake, slightly acidic, occupied the floor of the N crater. Sulfur deposition from two fumarolic vents 25-40 m N of the hot water lakes at ~950 m elev has produced large vent structures. The smaller structure is bright-yellow, tea-kettle-shaped, and ~1 m high. Pressurized steam, consisting of water vapor and sulfur, was being emitted horizontally towards the E from a small vent opening. The larger structure is ~4-5 m high with two peaks, one on each side of the top. An elongated opening (~2 m long and 60 cm high) in the side of the edifice was emitting a large plume of sulfuric steam, but with less force than at the smaller vent.

On 14 April 2004 a fishing craft reported a white gas plume emerging from Tatarinov volcano. That volcano lies near the opposite (southern) end of Paramushir Island. The plume came from Tatarinov's fumarolic field and remained at low altitude following the Tukharka river. Also in the southern part of Paramushir island, the volcanoes Chikurachki (last active 17-18 April 2003, SEAN 28:07) and Fuss Peak (SEAN 12:04) were both reported quiet.

Small ash deposits in January 2005 but plumes later became infrequent

A few gas-and-steam plumes from Ebeko were reported during February-April 2004 (BGVN 29:04). The most recent previous eruption was in January 1991. On 30 January 2005 the Kamchatka Volcanic Eruptions Response Team (KVERT) raised the Concern Color Code at Ebeko from Green to Yellow after reports of a strong smell of sulfur on 27 and 28 January in the town of Severo-Kurilsk, ~ 7 km from Ebeko. Observations by Leonid and Tatiana Kotenko in Severo-Kurilsk during May-July 2004 included occasional gas-and-steam plume rising as high as 250 m above the volcano during clear weather and fumarolic plumes moving close to the ground. There was no visible activity in August, but a few plumes were seen again from September to November.

During 28 January, a white gas-and-steam plume was seen from Severo-Kurilsk rising 400 m above the volcano. Summit observations the next day revealed a yellow-gray, 5-m-diameter, column rising 300 m from a vent on the NE side of the active crater. Three ash layers 2-3 mm thick were noted 10 m from the vent, and ash extended ~ 500 m E into the crater. At this time a new 7 x 12 m turquoise lake had developed in the SW part of the active crater. The lake disappeared on 30 January, and there was intensive fumarolic activity where it had been. Shallow earthquakes were recorded at the Severo-Kurilsk seismic station.

On 1 February gas-and-steam plumes rose to 450 m above Ebeko's crater and drifted NE. On 7 February a small emission of steam, gas, and possibly ash rose ~ 1 km above the crater and drifted ~ 12 km SE. On 8 and 9 February plumes rose to 600 m and thin ash deposits were noted in the town of Severo-Kurilsk.

The following information came to KVERT from observers in Severo-Kurilsk (Leonid and Tatiana Kotenko). On 15-16 February a dark-gray column rose up to 500 m above the crater. A dark-gray plume extended 6 km E and a light-gray plume 7 km SE. On 16 February ashfall together with snowfall was noted over the strait to the E of Paramushir Island. On 17 February a white column up to 250 m above the crater was observed. On 12 February and 16-17 February a strong smell of a H2S was noted at Severo-Kurilsk. On 18-19 February white gas-and-steam columns 5 m in diameter rose from the two vents up to 450 m above the crater and a new lake (10 x 10 m) on the floor of the active crater was observed. On 25 February white gas-and-steam plumes rose to 450 m and 1,000 m above the crater. Gas-and-steam plumes were also observed on 1-2, 4-5, and 9 March. No ash was seen. A strong smell of H2S was noted at Severo-Kurilsk on 25 February and 2 March.

About 20 seismic events of less than Ml 2.0 were observed during 1-9 March at the Severo-Kurilsk seismic station. No seismic activity was observed from 12 to 14 March. On 15 March two seismic events were noted. There was no seismicity during 18-25 March, so KVERT reduced the hazard status from Yellow to Green, the lowest level.

The Russian Emergency Situations Ministry's Sakhalin department reported renewed activity on 27 June in the form of emission clouds rising to a maximum height of 200 m above the crater and drifting SW. KVERT did not report any activity, and the Concern Color Code for Ebeko remained at Green.

Occasional steam plumes with ash from mid-2005 to mid-2009

Our most recent report on Ebeko described minor seismic events between January-June 2005, accompanied by occasional plumes sometimes depositing minor ash (BGVN 30:06). Ebeko lacks a dedicated seismometer; therefore, the Kamchatkan Volcanic Eruption Response Team (KVERT) generally monitors the volcano with visual and satellite observations. The town of Severo-Kurilsk, ~ 7 km E of the summit, has been subjected to considerable environmental stress due to emissions in the past several years (Kotenko and Kotenko, 2009). The volcano is located at the N end of Paramushir Island, just S of the Kamchatka Peninsula. The island hosts five other volcanoes active in the Holocene, including Chikurachki, which was active in 2002, 2003, 2005, 2007, and as recently as September 2008.

About 29 July 2005, KVERT raised the Concern Color Code from Green (the lowest level) to Yellow. During 22-29 July new fumaroles were noted in the active crater, and there was one explosion reported. This types of activity had not been observed since 1982. During 3-9 August fumarolic activity continued. During the week of 5-12 August 2005 weak fumarolic activity was noted, but no volcanic activity was visible on satellite imagery. Strong fumarolic activity occurred during 9-16 September, and gas temperatures reached 480°C. During the week 22-28 February 2006, KVERT reported that no significant changes in activity had been seen on satellite imagery or via ground observations for several months, so the Concern Color Code was reduced to Green. A weak scent of hydrogen sulfide and chlorine gas was sometimes noted in Severo-Kurilsk.

No additional information was available about Ebeko until March 2007. According to a news article in RIA Novosti, on 22 March gas-and-steam clouds from the volcano rose to an altitude of 1.3-1.5 km. Nearby residents smelled sulfur and chlorine.

Ebeko was not reported on again until February 2009. According to the Tokyo Volcanic Ash Advisory Center (VAAC) and KVERT, between 11 February and 18 June 2009, the volcano emitted a series of gas-and-steam plumes containing some ash (table 3, figure 1). During 29 January-23 February, the cumulative ashfall was 80 g/m2.

Ashfall deposits in Severo-Kurilsk on 13-14, 18, 29, and 31 March 2009 (figures 2 and 3) were up to 2 mm deep. The town also experienced light ashfall on 5 and 22-23 April. Accordingly, on 3 April 2009 the Level of Concern Color Code was raised to Yellow. On 31 July, KVERT reported that activity had remained low since 13 July, and thus lowered the Level of Concern Color Code to Green.

Hazards and impacts on Severo-Kurilsk. Kotenko and Kotenko (2009) discussed the environmental impacts of Ebeko on Severo-Kurilsk. Threats include lahars, ashfalls, atmospheric poisoning from volcanic gases (particularly during periods of strong fumarolic activity), and the pollution of potable water supplies. Narrow river gorges descending the volcano can direct volcanic gas into Severo-Kurilsk, which lies in a lowland, accentuating the air pollution problem. The study noted the stresses on inhabitants during strong fumarolic activity of the kind seen during the 2- to 3-year-long intervals leading to eruptions. Historical eruptions occurred in 1793, 1833-34, 1859, 1934-35, 1967-71, and 1987-90.

Gas-and-steam plumes and ash plumes in 2009 and 2010

Our most recent report on Ebeko (BGVN 34:08) described intermittent activity from mid-2005 to mid-2009, primarily plumes that sometimes deposited minor ash. Ebeko lacks a dedicated seismometer; therefore, the Kamchatkan Volcanic Eruption Response Team (KVERT) generally monitors the volcano with visual and satellite observations (figure 4). Intermittent plumes continued in 2009-2010.

Activity during October 2009. Based on analyses of satellite imagery, the Tokyo VAAC reported two possible eruption plumes from Ebeko in October 2009. The first plume, reported on 15 October 2009, rose to an altitude of 10.7 km and drifted NE. The second plume, on 26 October, rose to an altitude of 8.8 km and drifted E.

KVERT reported that on 26 October a gas-and-steam plume was seen by observers in Severo-Kurilsk (figure 4), a town about 7 km E of Ebeko. The plume rose about 300 m above the crater and drifted 1-2 km NNE. Gas-and-steam plumes rose 250 m above the crater and drifted 2 km E on 28 October and NNE on 29 October 2009.

Activity during June-July 2010. KVERT reported that activity increased on 2 July according to observers in Severo-Kurilsk (figure 5). Explosions produced ash plumes that rose to an altitude of 1.8 km and drifted SSE. The Aviation Color Code was raised to Yellow. On 23 July, KVERT reported that the Aviation Color Code was lowered to Green. Visual observations and satellite data indicated no activity from the volcano during 16-23 July.

New eruption with ash explosions began on 20 October 2016; ongoing through May 2017

Following explosions that produced ash plumes in early July 2010 (BGVN 36:07), no additional activity was noted from Ebeko by the Kamchatkan Volcanic Eruption Response Team (KVERT) until October 2016. This rather remote volcano on the N end of Paramushir Island in the Kuril Islands (figure 6) contains many craters, lakes, and thermal features (figure 7). Ash plumes were observed on 20 October 2016 and continued to be detected intermittently through 19 April 2017 (table 4).

According to observers about 7 km E in the city of Severo-Kurilsk, a gas-and-steam plume containing a small amount of ash rose from Ebeko on 20 October 2016 (figure 8), marking the start of its most recent eruption. The Aviation Color Code (ACC) was raised from Green to Yellow. Later that day observers noted gas, steam, and ash plumes rising from the volcano. Ground-based and satellite observations during 21-23 October indicated quiet conditions; consequently, the ACC was lowered to Green on 24 October.

On 8-9 December 2016 the ACC was again raised to Yellow when a gas and steam plume containing a small amount of ash was observed. Ash rose from both Sredniy Crater (middle) and Severny Crater (northern) during 9-10 December (figure 9). Further ash plumes were seen during 17-27 December the ACC was raised to Orange. Minor ash was reported during 30 December 2016-6 January 2017, along with gas and steam plumes. An ash plume rose up to 2 km altitude on 19 January (figure 10), and ash fell in Severo-Kurilsk on 30 January. More frequent explosions took place between 24 February and 19 April 2017 (table 4). Simultaneous explosions from two craters was observed on 15 April (figure 11).

Continuing frequent ash explosions through November 2017, typically to about 2 km altitude

Ebeko volcano is located on the remote N end of Paramushir Island in the Kuril Islands and contains many craters, lakes, and thermal features. Eruptions and ash plumes were observed at Ebeko in early July 2010 (BGVN 36:07). No additional activity was reported from Ebeko until October 2016, marking the start of the more recent eruptive cycle. New explosive eruptions accompanied by ash fall began on 20 October 2016 through April 2017 (BGVN: 42:08). Explosive eruptions, ash plumes, ash falls were observed and reported at a regular frequency during this reporting period from May through November 2017 (table 5). Eruptions were reported by observations from residents in the town of Severo-Kurilsk, located about 7 km E of Ebeko, by volcanologists and by satellite imagery. The Kamchatkan Volcanic Eruption Response Team (KVERT) is responsible for monitoring Ebeko, and is the primary source of information. The Aviation Color Code (ACC) remained at Orange throughout this reporting period. This color is the second highest level of the four color scale.

Ash explosions remained frequent through May 2018, with plumes typically rising more than 1 km

The most recent eruption at Ebeko, a remote volcano in the Kuril Islands, began in October 2016 (BGVN 42:08) with explosive eruptions accompanied by ashfall. Frequent ash explosions were observed through November 2017 and the eruption remained ongoing at that time (BGVN 43:03). Activity consisting of explosive eruptions, ash plumes, and ashfalls continued during December 2017 through May 2018 (table 6). Eruptions were observed by residents in Severo-Kurilsk (about 7 km E), by volcanologists, and based on satellite imagery. The Kamchatkan Volcanic Eruption Response Team (KVERT) is responsible for monitoring Ebeko, and is the primary source of information. The Aviation Color Code (ACC) remained at Orange throughout this reporting period. This color is the second highest level of the four color scale.

Frequent ash explosions continue during June-November 2018

Typical activity during the current eruption at Ebeko that began in October 2016 consists of numerous explosions and associated ash plumes (BGVN 43:06). The Kamchatkan Volcanic Eruption Response Team (KVERT) is responsible for monitoring this remote volcano, and has an observation site at Severo-Kurilsk, 7 km E. The current report reviews events from June through November 2018. During the reporting period, the Aviation Color Code remained at Orange, the second highest level of the four-color scale.

According to KVERT, numerous moderate explosions every month generated ash plumes (figure 18 an d19) that rose between 2.5-6 km in altitude, with most between 3 and 4.5 km (table 7). Occasionally, ashfall was reported in Severo-Kurilsk. KVERT reported that thermal anomalies began about mid-August and continued through November.

Thermal anomalies, based on MODIS satellite instruments analyzed using the MODVOLC algorithm, were observed only twice during the reporting period, on 30 August and 29 September 2018. The MIROVA (Middle InfraRed Observation of Volcanic Activity) volcano hotspot detection system, also based on analysis of MODIS data, detected a few scattered anomalies, almost all of which were concentrated during the latter half of August through September. These data are consistent with KVERT's observations of thermal anomalies beginning in mid-August.

Continuing frequent moderate explosions though May 2019; ashfall in Severo-Kurilsk

The Ebeko volcano, located on the northern end of the Paramushir Island in the Kuril Islands, consists of many craters, lakes, and thermal features and has been frequently erupting since late February 2017. Typical activity includes ash plumes, explosive eruptions, and gas-and-steam activity. The previous report through November 2018 (BGVN 43:12) described frequent ash explosions that sometimes caused ashfall in Severo-Kurilsk (7 km E). The primary source of information is the Kamchatka Volcanic Eruptions Response Team (KVERT). This report updates the volcanic activity at Ebeko for December 2018 through May 2019.

Frequent moderate explosive activity continued after November 2018. Volcanologists in Severo-Kurilsk observed explosions sending up ash, which drifted N, NE, and E, resulting in ash falls on Severo-Kurilsk on 28 different days between December 2018 and March 2019. On 25 December 2018 an explosion sent ash up to a maximum altitude of 4.5 km and then drifted N for about 5 km. Explosions occurring on 8-10 March 2019 sent ash up to an altitude of 4 km, resulting in ashfall on Severo-Kurilsk on 9-10 March 2019. An ash plume from these explosions rose to a height of 2.5 km and drifted to a maximum distance of 30 km ENE.

Satellite data analyzed by KVERT registered 12 thermal anomalies from December 2018 through May 2019. According to satellite data analyzed by MIROVA (Middle InfraRed Observation of Volcanic Activity), only one thermal anomaly was recorded from December 2018-May 2019, and no hotspot pixels were recognized using satellite thermal data from the MODVOLC algorithm.

Frequent moderate explosions, ash plumes, and ashfall continue through November 2019

Activity at Ebeko includes frequent explosions that have generated ash plumes reaching altitudes of 1.5-6 km over the last several years, with the higher altitudes occurring since mid-2018 (BGVN 43:03, 43:06, 43:12, 44:07). Ash frequently falls in Severo-Kurilsk (7 km ESE), which is monitored by the Kamchatka Volcanic Eruptions Response Team (KVERT). This activity continued during June through November 2019; the Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Explosive activity during December 2018 through November 2019 often sent ash plumes to altitudes between 2.2 to 4.5 km, or heights of 1.1 to 3.4 km above the crater (table 8). Eruptions since 1967 have originated from the northern crater of the summit area (figure 20). Webcams occasionally captured ash explosions, as seen on 27 July 2019(figure 21). KVERT often reported the presence of thermal anomalies; particularly on 23 September 2019, a Sentinel-2 thermal satellite image showed a strong thermal signature at the crater summit accompanied by an ash plume (figure 22). Ashfall is relatively frequent in Severo-Kurilsk (7 km ESE) and can drift in different direction based on the wind pattern, which can be seen in satellite imagery on 30 October 2019 deposited NE and SE from the crater(figure 23).

Frequent moderate explosions, ash plumes, and ashfall continue, December 2019-May 2020

The current moderate explosive eruption of Ebeko has been ongoing since October 2016, with frequent ash explosions that have reached altitudes of 1.3-6 km (BGVN 42:08, 43:03, 43:06, 43:12, 44:12). Ashfall is common in Severo-Kurilsk, a town of about 2,500 residents 7 km ESE, where the Kamchatka Volcanic Eruptions Response Team (KVERT) monitor the volcano. During the reporting period, December 2019-May 2020, the Aviation Color Code remained at Orange (the second highest level on a four-color scale).

During December 2019-May 2020, frequent explosions generated ash plumes that reached altitudes of 1.5-4.6 km (table 9); reports of ashfall in Severo-Kurilsk were common. Ash explosions in late April caused ashfall in Severo-Kurilsk during 25-30 April (figure 24), and the plume drifted 180 km SE on the 29th. There was also a higher level of activity during the second half of May (figure 25), when plumes drifted up to 80 km downwind.

Continued explosions, ash plumes, and ashfall; June-November 2020

Volcanism at Ebeko, located on the N end of the Paramushir Island in the Kuril Islands, has been ongoing since October 2016, characterized by frequent moderate explosions, ash plumes, and ashfall in Severo-Kurilsk (7 km ESE) (BGVN 45:05). Similar activity during this reporting period of June through November 2020 continues, consisting of frequent explosions, dense ash plumes, and occasional ashfall. Information for this report primarily comes from the Kamchatka Volcanic Eruptions Response Team (KVERT) and satellite data.

Activity during June was characterized by frequent, almost daily explosions and ash plumes that rose to 1.6-4.6 km altitude and drifted in various directions, according to KVERT reports and information from the Tokyo VAAC advisories using HIMAWARI-8 satellite imagery and KBGS (Kamchatka Branch of the Geophysical Service) seismic data. Satellite imagery showed persistent thermal anomalies over the summit crater. On 1 June explosions generated an ash plume up to 4.5 km altitude drifting E and S, in addition to several smaller ash plumes that rose to 2.3-3 km altitude drifting E, NW, and NE, according to KVERT VONA notices. Explosions on 11 June generated an ash plume that rose 2.6 km altitude and drifted as far as 85 km N and NW. Explosions continued during 21-30 June, producing ash plumes that rose 2-4 km altitude, drifting up to 5 km in different directions (figure 26); many of these eruptive events were accompanied by thermal anomalies that were observed in satellite imagery.

Explosions continued in July, producing ash plumes rising 2-5.2 km altitude and drifting for 3-30 km in different directions. On 3, 6, 15 July explosions generated an ash plume that rose 3-4 km altitude that drifted N, NE, and SE, resulting in ashfall in Severo-Kurilsk. According to a Tokyo VAAC advisory, an eruption on 4 July produced an ash plume that rose up to 5.2 km altitude drifting S. On 22 July explosions produced an ash cloud measuring 11 x 13 km in size and that rose to 3 km altitude drifting 30 km SE. Frequent thermal anomalies were identified in satellite imagery accompanying these explosions.

In August, explosions persisted with ash plumes rising 1.7-4 km altitude drifting for 3-10 km in multiple directions. Intermittent thermal anomalies were detected in satellite imagery, according to KVERT. On 9 and 22 August explosions sent ash up to 2.5-3 km altitude drifting W, S, E, and SE, resulting in ashfall in Severo-Kurilsk. Moderate gas-and-steam activity was reported occasionally during the month.

Almost daily explosions in September generated dense ash plumes that rose 1.5-4.3 km altitude and drifted 3-5 km in different directions. Moderate gas-and-steam emissions were often accompanied by thermal anomalies visible in satellite imagery. During 14-15 September explosions sent ash plumes up to 2.5-3 km altitude drifting SE and NE, resulting in ashfall in Severo-Kurilsk. On 22 September a dense gray ash plume rose to 3 km altitude and drifted S. The ash plume on 26 September was at 3.5 km altitude and drifted SE (figure 27).

During October, near-daily ash explosions continued, rising 1.7-4 km altitude drifting in many directions. Intermittent thermal anomalies were identified in satellite imagery. During 7-8, 9-10, and 20-22 October ashfall was reported in Severo-Kurilsk.

Explosions in November produced dense gray ash plumes that rose to 1.5-5.2 km altitude and drifted as far as 5-10 km, mainly NE, SE, E, SW, and ENE. According to KVERT, thermal anomalies were visible in satellite imagery throughout the month. On clear weather days on 8 and 11 November Sentinel-2 satellite imagery showed ashfall deposits SE of the summit crater from recent activity (figure 28). During 15-17 November explosions sent ash up to 3.5 km altitude drifting NE, E, and SE which resulted in ashfall in Severo-Kurilsk on 17 November. Similar ashfall was observed on 22-24 and 28 November due to ash rising to 1.8-3 km altitude (figure 29). Explosions on 29 November sent an ash plume up to 4.5 km altitude drifting E (figure 29). A Tokyo VAAC advisory reported that an ash plume drifting SSE on 30 November reached an altitude of 3-5.2 km.

Frequent explosions, ash plumes, and ashfall persist during December 2020-May 2021

Ebeko is located on the N end of the Paramushir Island in the Kuril Islands and consists of three summit craters aligned SSW-NNE. Its current eruption has been ongoing since October 2016 and has recently been characterized by explosions that generate ash plumes and some ashfall on the flanks (BGVN 45:12). Similar activity of near daily explosions and ash plumes continued during this reporting period of December 2020 through May 2021 based on information from the Kamchatka Volcanic Eruptions Response Team (KVERT) and satellite data.

During December 2020 frequent explosions, reported by volcanologists in Severo-Kurilsk (7 km ESE) viewing video images, generated ash plumes to 2.1-5 km altitude that drifted as far as 10 km E, SE, NW, S, and NE. Satellite data often showed that the volcano was obscured by clouds. A thermal anomaly was noted in satellite data during 18-19 December. On 19 December an explosion produced an ash plume that rose to 4 km altitude and drifted 5 km E (figure 32).

Intermittent explosions, ash plumes, and ashfall during June-November 2021

Ebeko occupies the N end of Paramushir Island in the Kuril Islands, consisting of three summit craters. Recorded eruptions since the late 18th century have been restricted to small-to-moderate explosions from the summit craters, as well as intense fumarolic activity. The current eruption period began during October 2016 and more recently has been characterized by frequent explosions, ash plumes, and ashfall (BGVN 46:06). This report covers activity during June through November 2021, describing similar activity of explosions, ash plumes, and ashfall, based on information from the Kamchatka Volcanic Eruptions Response Team (KVERT), the Tokyo Volcanic Ash Advisory Center (VAAC), and satellite data.

Frequent explosions were reported by volcanologists in Severo-Kurilsk (7 km E) during June and generated ash plumes that rose as high as 1.5-4.5 km altitude and drifted in different directions. A thermal anomaly was detected in satellite images on 2 and 10 June. An ash plume on 4 June rose to 3-3.4 km altitude and drifted SE, based on information from a Tokyo VAAC notice. Another ash plume on 6 June rose to 3.7 km altitude and extended NE. Volcanologists from Severo-Kurilsk reported an explosion that ejected ash to 4 km altitude that drifted 5 km NE on 11 June. The next day, on 12 June an explosion produced an ash plume that rose to 2-3 km altitude and drifted 6 km NE. On 22 June an ash plume rose to 2.2 km altitude and drifted 3 km SE.

Similar activity continued into July, with ash rising to 1.8-4.5 km altitude and drifting in multiple directions. A thermal anomaly was detected in satellite imagery during 5-7, 10, 12, 16, 20-22, and 25 July. An explosion on 4 July produced an ash plume that rose to 3.7 km altitude and drifted S (figure 36). On 10 July an explosion generated an ash plume that rose to 3 km altitude and drifted 5 km E. Explosions during 12-13 July produced ash plumes that rose to 2.5-3 km altitude and extended 3-5 km E and SE. On 29 July an explosion generated an ash plume that rose to 2 km altitude and drifted as far as 10 km S.

Explosions persisted in August and the resulting ash plumes rose to 1.8-4.6 km altitude and drifted in different directions. On 7 August an explosion rose to 2 km altitude and drifted 3 km SE. An explosion on 25 August produced an ash plume that rose to 3.7 km altitude and drifted 10 km SE. A thermal anomaly was reported in satellite images on 1, 6, 9, 11, 13-14, 20, and 23-25 August. On 25 August an explosion generated an ash plume that rose to 3.7 km altitude and drifted 10 km SE (figure 37).

Explosions in September produced ash plumes that rose to 1.3-2.5 km altitude and drifted in different directions. On 6 and 8 September ashfall was reported in Severo-Kurilsk. During the latter half of September, moderate gas-and-steam plumes were observed, which persisted into October. According to a KVERT weekly report, an explosion on 10 October produced an ash plume that rose to 2.5 km altitude and drifted NE. However, the plume could not be confirmed in satellite or webcam images. On 22 October KVERT lowered the Aviation Color Code (ACC) to Yellow (the second lowest level on a four-color scale), noting that the last visible thermal anomaly over the volcano occurred on 25 August.

A strong explosion was reported at 2340 on 25 October, based on HIMAWARI-8 satellite data. The explosion sent an ash plume up to 6.2 km altitude, which extended for 230 km to the E and later drifted to the SE. In addition, a thermal anomaly was noted over the volcano. Notable ashfall was reported at Severo-Kurilsk. Another explosion on 31 October generated an ash plume that rose to 1.8 km altitude and drifted 5 km NE.

During November, with ash plumes rising to 1.4-2.6 km altitude, in addition to moderate gas-and-steam plumes. On 2 November an ash plume rose to 2.6 km altitude and drifted SE. Explosions were also detected each day during 5-9 November, with ash plumes rising as high as 2.3 km altitude and drifting SE and E. On 7 November volcanologists from Severo-Kurilsk reported an explosion sending ash up to 2.2 km altitude that drifted 5 km NE. On 26 November KVERT lowered the Aviation Color Code (ACC) to Yellow (the second lowest on a four-color scale), noting that although gas-and-steam plumes persisted, the last recorded eruptive activity occurred on 9 November.

According to MIROVA (Middle InfraRed Observation of Volcanic Activity) data, four thermal pixels were detected between June and August 2021 (figure 38). During this time, Sentinel-2 natural color satellite images showed ash plumes and ashfall (dark gray) on the flanks resulting from frequent explosions at the summit (figure 39).

Intermittent explosions, ash plumes, and thermal activity during June-September 2022

Ebeko is located on the N end of Paramushir Island in the Kuril Islands and consists of three summit craters. Eruptions dating back to the late 18th century have been characterized as small-to-moderate explosions from the summit crater, accompanied by intense fumarolic activity. The previous eruption period consisted of intermittent explosions, ash plumes, and ashfall that ended in November 2021 (BGVN 46:12). This reporting period during December 2021 through September 2022 covers a new eruption that began in June 2022 and consisted of similar intermittent explosions, ash plumes, and thermal activity, based on information from the Kamchatka Volcanic Eruptions Response Team (KVERT) and satellite data.

Activity during early December 2021 consisted of ongoing moderate gas-and-steam activity after the eruption that ended in November 2021. No significant activity was observed until 12 June 2022 when small phreatic bursts were detected, along with moderate explosions that generated ash up to 2.5 km altitude (figure 40). As a result, the Aviation Color Code (ACC) was raised to Yellow (the second lowest level on a four-color scale) on 17 June. Explosions on 18 and 22-23 June sent ash plumes to 2.5 km altitude, which drifted S, SE, and NE. A thermal anomaly was visible in satellite images on 22 June. At 1510 on 24 June an ash plume rose to 2.5 km altitude and drifted 5 km SE, which prompted KVERT to increase the ACC to Orange (the second highest level on a four-color scale). During 24-25 and 30 June explosions generated ash plumes that rose to 3.5 km altitude and drifted NW, NE, and SE.

According to volcanologists in Severo-Kurilsk (Paramushir Island, about 7 km E) explosions continued during July, generating ash plumes that rose to 2.7-3 km altitude and drifted E on 3 July; a thermal anomaly was visible in satellite images. On 7 July explosions produced ash plumes that rose to 1.8 km altitude and drifted SE as far as 5 km. During 10-11 and 13 July explosions sent ash plumes to 1.5-2.8 km altitude and drifted SE and satellite images showed a thermal anomaly over the volcano. According to observers, an explosion at 1740 local time on 16 July produced an ash plume that rose to 4.5 km altitude and drifted 5 km SE. On 27 July an explosion generated an ash plume that rose to 2.5 km altitude and drifted 10 km N (figure 41). Subsequent explosions during 28-30 July generated ash plumes to 4.5 km altitude that drifted SE and S.

Explosive activity and ash plumes continued during August. A thermal anomaly over the volcano was identified in satellite images on 1, 3-5, and 7-8 August. Webcam images from Severo-Kurilsk showed explosions that generated ash plumes to 2-3.5 that drifted as far as 3 km SE during 4-5 and 7-8 August (figure 42). A thermal anomaly was identified in satellite images on 13, 18-19, 22, and 25 August. During 15-18 August explosions generated ash plumes that rose to 3.5 km altitude. During 17-18 August ash plumes drifted more than 65 km SE and 5 km NE. Explosions during 19, 22-26, 28, and 30-31 August produced an ash plume that rose to 3.5 km altitude and drifted N, E, and NE. Thermal anomalies were visible in satellite images on 25 and 31 August. Ashfall was reported in Severo-Kurilsk on 30 August.

Ongoing moderate explosions continued through September, according to volcanologists in Severo-Kurilsk. Thermal anomalies were visible in satellite images during 3, 5-8, 12-13, and 18 September. During 4-5 September explosions generated ash plumes that rose to 4 km altitude and drifted as far as 50 km E and SE. On 5 and 7-8 September explosions produced ash plumes that rose to 3 km and 2-2.5 altitude and drifted 5 km SE and NNE, respectively. During 9-11 September explosions generated ash plumes that rose to 1.9-3.6 km altitude and drifted 5-7 km NNE and E. Similar explosions during 22-24 and 27-28 September produced ash plumes that rose to 3.5 km altitude and drifted E and N. As a result, ashfall was reported in Severo-Kurilsk during 9-10 and 20-23 September. On 23 and 28 September webcam images showed an explosion that produced an ash plume to 2.7 km and 1.9 altitude and drifted 5 km E, respectively. Ashfall was also reported in Severo-Kurilsk during 28 September. A thermal anomaly was visible on 23 and 28 September in satellite data.

According to MIROVA (Middle InfraRed Observation of Volcanic Activity) data, four low-power thermal anomalies were detected during late July and early to mid-August 2022 (figure 43). This thermal activity, also seen in Sentinel-2 infrared satellite images, was sometimes accompanied by ash plumes that drifted SE and SW from the summit due to frequent explosions (figure 44).

Continued explosions, ash plumes, and ashfall during October 2022-May 2023

Ebeko, located on the N end of Paramushir Island in the Kuril Islands, consists of three summit craters along a SSW-NNE line at the northern end of a complex of five volcanic cones. Eruptions date back to the late 18th century and have been characterized as small-to-moderate explosions from the summit crater, accompanied by intense fumarolic activity. The current eruption period began in June 2022 and has recently consisted of frequent explosions, ash plumes, and thermal activity (BGVN 47:10). This report covers similar activity during October 2022 through May 2023, based on information from the Kamchatka Volcanic Eruptions Response Team (KVERT) and satellite data.

Activity during October consisted of explosive activity, ash plumes, and occasional thermal anomalies. Visual data by volcanologists from Severo-Kurilsk showed explosions producing ash clouds up to 2.1-3 km altitude which drifted E, N, NE, and SE during 1-8, 10, 16, and 18 October. KVERT issued several Volcano Observatory Notices for Aviation (VONA) on 7, 13-15, and 27 October 2022, stating that explosions generated ash plumes that rose to 2.3-4 km altitude and drifted 5 km E, NE, and SE. Ashfall was reported in Severo-Kurilsk (Paramushir Island, about 7 km E) on 7 and 13 October. Satellite data showed a thermal anomaly over the volcano on 15-16 October. Visual data showed ash plumes rising to 2.5-3.6 km altitude on 22, 25-29, and 31 October and moving NE due to constant explosions.

Similar activity continued during November, with explosions, ash plumes, and ashfall occurring. KVERT issued VONAs on 1-2, 4, 6-7, 9, 13, and 16 November that reported explosions and resulting ash plumes that rose to 1.7-3.6 km altitude and drifted 3-5 km SE, ESE, E, and NE. On 1 November ash plumes extended as far as 110 km SE. On 5, 8, 12, and 24-25 November explosions and ash plumes rose to 2-3.1 km altitude and drifted N and E. Ashfall was observed in Severo-Kurilsk on 7 and 16 November. A thermal anomaly was visible during 1-4, 16, and 20 November. Explosions during 26 November rose as high as 2.7 km altitude and drifted NE (figure 45).

Explosions and ash plumes continued to occur in December. During 1-2 and 4 December volcanologists from Severo-Kurilsk observed explosions that sent ash to 1.9-2.5 km altitude and drifted NE and SE (figure 46). VONAs were issued on 5, 9, and 16 December reporting that explosions generated ash plumes rising to 1.9 km, 2.6 km, and 2.4 km altitude and drifted 5 km SE, E, and NE, respectively. A thermal anomaly was visible in satellite imagery on 16 December. On 18 and 27-28 December explosions produced ash plumes that rose to 2.5 km altitude and drifted NE and SE. On 31 December an ash plume rose to 2 km altitude and drifted NE.

Explosions continued during January 2023, based on visual observations by volcanologists from Severo-Kurilsk. During 1-7 January explosions generated ash plumes that rose to 4 km altitude and drifted NE, E, W, and SE. According to VONAs issued by KVERT on 2, 4, 10, and 23 January, explosions produced ash plumes that rose to 2-4 km altitude and drifted 5 km N, NE, E, and ENE; the ash plume that rose to 4 km altitude occurred on 10 January (figure 47). Satellite data showed a thermal anomaly during 3-4, 10, 13, 16, 21, 22, and 31 January. KVERT reported that an ash cloud on 4 January moved 12 km NE. On 6 and 9-11 January explosions sent ash plumes to 4.5 km altitude and drifted W and ESE. On 13 January an ash plume rose to 3 km altitude and drifted SE. During 20-24 January ash plumes from explosions rose to 3.7 km altitude and drifted SE, N, and NE. On 21 January the ash plume drifted as far as 40 km NE.

During February, explosions, ash plumes, and ashfall were reported. During 1, 4-5 and 7-8 February explosions generated ash plumes that rose to 4.5 km altitude and drifted E and NE; ashfall was observed on 5 and 8 February. On 6 February an explosion produced an ash plume that rose to 3 km altitude and drifted 7 km E, causing ashfall in Severo-Kurilsk. A thermal anomaly was visible in satellite data on 8, 9, 13, and 21 February. Explosions on 9 and 12-13 February produced ash plumes that rose to 4 km altitude and drifted E and NE; the ash cloud on 12 February extended as far as 45 km E. On 22 February explosions sent ash to 3 km altitude that drifted E. During 24 and 26-27 February ash plumes rose to 4 km altitude and drifted E. On 28 February an explosion sent ash to 2.5-3 km altitude and drifted 5 km E; ashfall was observed in Severo-Kurilsk.

Activity continued during March; visual observations showed that explosions generated ash plumes that rose to 3.6 km altitude on 3, 5-7, and 9-12 March and drifted E, NE, and NW. Thermal anomalies were visible on 10, 13, and 29-30 March in satellite imagery. On 18, 21-23, 26, and 29-30 March explosions produced ash plumes that rose to 2.8 km altitude and drifted NE and E; the ash plumes during 22-23 March extended up to 76 km E. A VONA issued on 21 March reported an explosion that produced an ash plume that rose to 2.8 km altitude and drifted 5 km E. Another VONA issued on 23 March reported that satellite data showed an ash plume rising to 3 km altitude and drifted 14 km E.

Explosions during April continued to generate ash plumes. On 1 and 4 April an ash plume rose to 2.8-3.5 km altitude and drifted SE and NE. A thermal anomaly was visible in satellite imagery during 1-6 April. Satellite data showed ash plumes and clouds rising to 2-3 km altitude and drifting up to 12 km SW and E on 3 and 6 April (figure 48). KVERT issued VONAs on 3, 5, 14, 16 April describing explosions that produced ash plumes rising to 3 km, 3.5 km, 3.5 km, and 3 km altitude and drifting 5 km S, 5 km NE and SE, 72 km NNE, and 5 km NE, respectively. According to satellite data, the resulting ash cloud from the explosion on 14 April was 25 x 7 km in size and drifted 72-104 km NNE during 14-15 April. According to visual data by volcanologists from Severo-Kurilsk explosions sent ash up to 3.5 km altitude that drifted NE and E during 15-16, 22, 25-26, and 29 April.

The explosive eruption continued during May. Explosions during 3-4, 6-7, and 9-10 May generated ash plumes that rose to 4 km altitude and drifted SW and E. Satellite data showed a thermal anomaly on 3, 9, 13-14, and 24 May. During 12-16, 23-25, and 27-28 May ash plumes rose to 3.5 km altitude and drifted in different directions due to explosions. Two VONA notices were issued on 16 and 25 May, describing explosions that generated ash plumes rising to 3 km and 3.5 km altitude, respectively and extending 5 km E. The ash cloud on 25 May drifted 75 km SE.

Thermal activity in the summit crater, occasionally accompanied by ash plumes and ash deposits on the SE and E flanks due to frequent explosions, were visible in infrared and true color satellite images (figure 49).
