Smithsonian / USGS Weekly Volcanic Activity Report

Weekly Volcanic Activity Map

The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian's Global Volcanism Program and the US Geological Survey's Volcano Hazards Program. Updated by 2300 UTC every Wednesday, notices of volcanic activity posted on these pages are preliminary and subject to change as events are studied in more detail.

This is not a comprehensive list of all of Earth's volcanoes erupting during the week, but rather a summary of activity that meet criteria discussed in detail in the "Criteria and Disclaimers" section. Carefully reviewed, detailed narratives on various volcanoes are published as reports of the Bulletin of the Global Volcanism Network.

 Criteria & Disclaimers

Criteria



The Weekly Volcanic Activity Report does not necessarily include all volcanic activity that occurred on Earth during the week. More than a dozen volcanoes globally have displayed more-or-less continuous eruptive activity for decades or longer, and such routine activity is typically not reported here. Moreover, Earth's sea-floor volcanism is seldom reported even though in theory it represents the single most prolific source of erupted material. The Weekly Volcanic Activity Report summarizes volcanic activity that meets one or more of the following criteria:

- A volcano observatory raises or lowers the alert level at the volcano.
- A volcanic ash advisory has been released by a volcanic ash advisory center (VAAC) stating that an ash cloud has been produced from the volcano.
- A verifiable news report of new activity or a change in activity at the volcano has been issued.
- Observers have reported a significant change in volcanic activity. Such activity can include, but is not restricted to, pyroclastic flows, lahars, lava flows, dome collapse, or increased unrest.

Volcanoes are included in the "New Activity/Unrest" section of the Weekly Volcanic Activity Report if the activity occurs after at least 3 months of quiescence. Once a volcano is included in the "New Activity/Unrest" section, updates will remain in that section unless the activity continues for more than 1 month without escalating, after which time updates will be listed in the "Continuing Activity" section. Volcanoes are also included in the "New Activity/Unrest" section if the volcano is undergoing a period of relatively high unrest, or increasing unrest. This is commonly equal to Alert Level Orange on a scale of Green, Yellow, Orange, Red, where Red is the highest alert. Or alert level 3 on a scale of 1-4 or 1-5.

It is important to note that volcanic activity meeting one or more of these criteria may occur during the week, but may not be included in the Weekly Volcanic Activity Report because we did not receive a report.

Disclaimers



1. The Weekly Volcanic Activity Report is intended to provide timely information about global volcanism on a weekly basis. Consequently, the report is generated rapidly by summarizing volcanic reports from various sources, with little time for fact checking. The accuracy of the Weekly Volcanic Activity Report is dependent upon the quality of the volcanic activity reports we receive. Reports published in the Bulletin of the Global Volcanism Network are monthly, and more carefully reviewed, although all of the volcanoes discussed in the Weekly Volcanic Activity Report are not necessarily reported in the Bulletin. Because of our emphasis on rapid reporting on the web we have avoided diacritical marks. Reports are updated on the Weekly Volcanic Activity Report web page as they are received, therefore information may be included regarding events that occurred before the current report period.

2. Rapidly developing events lead to coverage that is often fragmentary. Volcanoes, their eruptions, and their plumes and associated atmospheric effects are complex phenomena that may require months to years of data analysis in order to create a comprehensive summary and interpretation of events.

3. Preliminary accounts sometimes contain exaggerations and "false alarms," and accordingly, this report may include some events ultimately found to be erroneous or misleading.

4. Many news agencies do not archive the articles they post on the Internet, and therefore the links to some sources may not be active. To obtain information about the cited articles that are no longer available on the Internet contact the source.

Report for Pavlof
AVO reported that the Strombolian eruption at Pavlof continued during 3-10 June. On 3 June the FAA webcam showed a high steam plume rising above a vent on the NE flank and lower-level ash from pyroclastic flows on the N flank. During 3-4 June seismicity remained unchanged and persistent elevated surface temperatures were detected in satellite images. A steam plume with minor amounts of ash but rich in sulfur dioxide drifted 100 km W. Incandescence from lava fountaining was visible in webcam images on 4 June. According to a news article, flights in and out of Cold Bay and Unalaska were canceled on 4 June, affecting about 200 people.

Two strong explosions were detected by the seismic network at 0205 and 0245 on 5 June. Lightning was detected by the World Wide Lightning Location Network indicating the presence of ash; satellite images did not detected ash above the meteorological cloud tops at about 8.5 km (28,000 ft) a.s.l. A third event was detected at 0844. The level of activity declined during 5-6 June; ash emissions appeared to be greatly reduced although cloud cover continued to obscure satellite views. Elevated surface temperatures were observed in mostly cloudy satellite images during 8-9 June. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.

Report for Santa Maria
On 6 June INSIVUMEH reported that the Santiaguito Observatory (OBSAN) was seriously affected by a large lahar that descended the Nima I river drainage on the S flank of Santa María's Santiaguito lava-dome complex. The lahar came in waves, 5-9 m high, was 80 m wide, and carried blocks up to 5 m in diameter. It overtopped the river banks and flowed to a nearby farm. The staff working at OBSAN had to evacuate; some important scientific equipment was lost and damaged. On 7 June a lahar descended the Samala river, a tributary of the Nima I river, carrying blocks up to 1 m in diameter, and lahars in the Nima I drainage had a sulfur odor. During 7-8 June slow-moving lava flows descended the E flank. Explosions during 8-9 June generated ash plumes that rose 500 m and drifted SW. Large avalanches in the collapsed area were incandescent at night. During 9-10 June explosions generated white and gray plumes that rose 500 m, the lava flows on the E flank produced avalanches, and Domo del Brujo began degassing.

Report for Zhupanovsky
KVERT reported that an eruption at Zhupanovsky began on 6 June, producing an ash plume that rose to an altitude of 6 km (19,900 ft) a.s.l., as suggested by Tokyo VAAC and UHPP notices. Cloud cover prevented views from satellite. The Aviation Color Code was raised to Yellow. Satellite images on 9 June showed ash plumes rising to altitudes of 3-4 km (9,800-13,100 ft) a.s.l. and drifting 60 km E.

Report for Chirinkotan
SVERT reported that an eruption at Chirinkotan had begun on 24 May; thermal anomalies and gas emissions sometimes containing ash were detected in satellite images. On 5 June seldom and weak thermal anomalies suggested cooling lava flows. The Aviation Color Code was lowered to Green.
Source: Sakhalin Volcanic Eruption Response Team (SVERT)
Report for Chirpoi
In a 5 June report, SVERT summarized activity at Snow, a volcano of Chirpoi, over the previous two years: an effusive eruption started on 10 November 2012, producing steam-and-gas emissions and thermal anomalies thorough April 2013; the volcano was quiet; steam-and-gas emissions and thermal anomalies were again detected starting on 12 July 2013, suggesting a new period of lava effusion. Weak thermal anomalies during 2-4 June implied cooling lava flows. The Aviation Color Code was lowered to Green.
Source: Sakhalin Volcanic Eruption Response Team (SVERT)
Report for Dukono
Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that on 4 June an ash plume from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted 150 km N. The next day an ash plume rose to an altitude of 3.7 km (12,000 ft) a.s.l. and drifted 55 km NW. On 9 June ash plumes rose to altitudes of 1.5-1.8 km (5,000-6,000 ft) a.s.l. and drifted 25-30 km NW.
Source: Darwin Volcanic Ash Advisory Centre (VAAC)
Report for Fuego
INSIVUMEH reported that on 5 June lahars descended Fuego's Honda (E), El Jute (SE), Ceniza (SSW), and Santa Teresa (S) drainages, carrying blocks as large as 1.5 m in diameter. Explosions during 5-6 June generated ash plumes that rose 250-350 m and drifted 8-10 km W and NW. Explosions during 8-10 June generated ash plumes that rose 350-750 m and drifted 8-10 km N. Incandescent material ejected 100 m above the crater landed on the flank and formed avalanches. On 9 June lahars in the El Jute and Las Lajas drainages carried blocks up to 1.5 m in diameter.

Report for Karymsky
KVERT reported that Strombolian and weak Vulcanian activity continued at Karymsky during 30 May-6 June. Satellite images detected no activity or were obscured by clouds. The Aviation Color Code remained at Orange.
Source: Kamchatkan Volcanic Eruption Response Team (KVERT)
Report for Kilauea
During 4-10 June HVO reported that the circulating lava lake occasionally rose and fell in the deep pit within Kilauea's Halema'uma'u Crater. Gas emissions remained elevated. The plume from the vent continued to deposit variable amounts of ash, spatter, and Pele's hair onto nearby areas; smaller particles may have been dropped several kilometers away.

At Pu'u 'O'o Crater, glow emanated from spatter cones on the N, SE, and S portions of the crater floor, and from a small lava lake in the NE spatter cone. On 22 May geologists mapped the farthest point of activity from the Kahauale’a 2 lava flow, 8.4 km NE of Pu’u 'O'o, and on 6 June they mapped four small breakouts as far as 6.5 km from Pu’u 'O'o. Smoke plumes rising from forested areas suggested advancing breakout flows.

Report for Sheveluch
KVERT reported that during 30 May-6 June lava-dome extrusion onto Shiveluch’s SE flank was accompanied by ash explosions, incandescence, hot avalanches, and fumarolic activity. Satellite images detected a thermal anomaly over the dome on 31 May and 1 and 3 June. The Aviation Color Code remained at Orange.
Source: Kamchatkan Volcanic Eruption Response Team (KVERT)
Report for Shishaldin
AVO reported that, although cloud cover frequently obscured views of Shishaldin during 4-9 June, seismicity indicated that the low-level eruption continued. Elevated surface temperatures at the summit were detected in mostly cloudy satellite images during 7-9 June. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.
Source: US Geological Survey Alaska Volcano Observatory (AVO)
Report for Ubinas
In a press release from 5 June, IGP's Observatorio Volcanologico de Arequipa (IGP-OVA) and Observatorio Vulcanológico del INGEMMET (OVI) reported that an Alert Level Orange continued for residents affected by the Ubinas eruption. Residents of Querapi and Tonohaya remained evacuated. The report noted that a significant and continuous release of ash emissions and gasses were observed during the previous days. Gas-and-ash plumes observed during 5-7 June rose 0.2-2 km above the crater. Minor ashfall was reported in Lloque and Yungas during 6-7 June.
