Shallow earthquakes in 2005; plume in 2008
This report discusses Avachinsky in 2001-2010. Following lava flows emitted in 1991 (BGVN 16:12), Avachinsky generated near-daily fumarolic plumes and generally low (background) seismicity (figure 3). The escaping gases contained sufficient sulfur to construct an area of sulfurous deposits at a prominent NW-trending crack on the SW rim of the summit crater. In 2001 a series of minor earthquakes were sometimes accompanied by gas-and-steam plumes (some with ash) (BGVN 26:11). Weak fumarolic activity and small mudflows also were observed.
By November 2001, seismic activity had declined to background levels where it apparently remained until 2005. On 8 November 2005, the Kamchatkan Volcanic Eruption Response Team (KVERT) reported that the number and energy of shallow earthquakes below Avachinsky had increased during the previous month. A weak thermal anomaly near the volcano's summit was visible on satellite imagery on 7 November. Seismicity increased significantly on 21 November, with very shallow earthquakes and several hybrid earthquakes. A weak thermal anomaly near the summit was visible on satellite imagery during 20-21 November.
During 2006 moderate fumarolic activity occurred, producing a steam plume about 700 m above crater. Seismicity was at background levels, with occasional weak seismic events at 500 m depth.
On 10 May 2008, a plume from Avachinsky rose to an altitude of 4.3 km and drifted S and E. KVERT did not detect ash by direct observation or on satellite imagery.

Droznin and others (2004?) note that "The heat discharge of the fumaroles may be estimated based on the geometrical characteristics of their clouds, taking into account local meteorological conditions.... The Avachinsky volcano fumaroles have been monitored since 2003 for the purpose of using the size of the fumaroles clouds to estimate the corresponding heat discharge. Its worth noting, that the real size of the thermo-clouds may be estimated only when there is 100% air saturation.
"The October 2001 eruption revealed an active steam-dominated reservoir below the lava plug of 1991. The swarm of the earthquakes hypocenters synchronized with the eruption 2001, showing the true geometrical size of the steam-dominated reservoir [figure 4]. This 1-km radius reservoir extends from the elevation of the lava plug at 2,750 m a.s.l. to -1,000 m a.s.l., where some north east trend shifting of the reservoir occurs. Similar earthquake distributions were detected in 2004."

During 26 October to 2 November seismicity was at background levels, with only weak earthquakes detected (magnitudes less than or equal to 1.2). During 29 October to 1 November, when the volcano was visible, weak-to-powerful gas-and-steam emissions were observed extending to the SE and E. The Concern Color Code was reduced from Yellow to Green.

During 19-26 October several gas-and-steam plumes rose above Avachinsky's crater, with the highest plume reaching 1 km and extending 20 km to the SE on 20 October. Seismic activity continued above background levels; ten earthquakes occurred with magnitudes of 1.3-2.1. The volcano remained at Concern Color Code Yellow.

During 12-19 October gas-and-steam plumes rose above Avachinsky's crater and until 18 October seismicity was at background levels or was not registered. During 18 and 19 October a series of weak local earthquakes were detected ~700 m beneath the summit. On 17 October a fracture was observed in the lava dome that extended E-SE and W-NW, joining the hottest parts of the edifice. The fracture extended 100-150 m down the flanks of the cone.The volcano remained at Concern Color Code Yellow.

Intense gas-and-steam plumes rose above the volcano several times during 6-11 October, with the highest plume climbing 500 m. During the report period, weak fumarolic activity occurred and seismicity was at background levels. Satellite imagery on 2 October showed a broad band of warm ground that appeared to follow the rim of the crater, with a small area of warm ground in the center of the crater. The volcano remained at Concern Color Code Yellow.

During 25 August until at least 5 October several earthquakes, with magnitudes between 1.2 and 2.5, were detected near Avachinsky. On 5 October at 0759 an earthquake inside the volcano's edifice was accompanied by a small gas-and-steam explosion with small amounts of ash that rose less than 1 km above the crater. A thin layer of ash covered the SE sector of the volcano's edifice. The same day at 1000 larger gas-and-steam plumes were observed rising above the volcano. Mudflows traveled 50-100 m down Avachinsky's SE slope. KVERT personnel believe the mudflows were caused by intensive activity at a single fumarole on the SE side of the summit. On 5 October the Concern Color Code at Avachinsky was raised from Green to Yellow.

Explosions feed 4-5-km tephra clouds; lava in crater; flank mudflows
An eruption began on 13 January with explosions at 1158 and 1203 that ejected ash clouds to 4-5 km above the crater. Ash fell on Petropavlovsk, roughly 30 km SSW. Lava was observed in the crater and small mudflows moved down the flanks. No pre-eruption seismicity was recorded, but seismic activity associated with the eruption was increasing as of 17 January.
Information Contacts: B. Ivanov, IV.
Lava dome filled crater during January 1991 eruption
The following supplements the preliminary report in 15:12. The eruption lasted until 30 January 1991, filling the summit crater (400-500 m in diameter) with ~21 x 106 metric tons of lava (figure 1). Circumferential and radial fissures 6 m deep covered the surface of the lava dome. Lava overflowed the S rim, feeding a flow that advanced 1.5 km down the SSE flank and short flows on the SW flank. Numerous fumaroles developed around the dome's margins.
Information Contacts: IVGG.
Fumarolic activity around 1991 dome
Fumarolic activity was occurring from numerous points around the margins of the January 1991 lava dome during a 13 May overflight. Numerous circumferential and radial fissures, previously observed in October 1991, covered the dome's surface, but the small lava flows that extended down the SSE and SW flanks were no longer visible.

Fumarolic activity
Fumarolic activity observed in late April from the crater area resulted from normal condensation of steam and was not caused by eruptive activity.
Information Contacts: V. Kirianov, IVGG.
Intense fumarolic activity
Summit crater observations were made by SVE team members during an overflight on 24 August. Fumarolic activity was very intense on and around the crater, and a very active fumarole field, with many yellow sulfur deposits, occupied a large area just below the rim on the SW slope. No fresh lava was visible on the surface of the lava plug that filled the summit crater . . . during the January 1991 eruption.
Information Contacts: H. Gaudru, SVE, Switzerland.
Usual fumarolic activity; seismicity low
Helicopter observations on 12-13 September revealed only the usual fumarolic activity, which was continuing through 6 November. Seismicity also remained at background levels of ~2-3 earthquakes/day through 28 October, except for an increase to ~8-10 earthquakes/day at depths of 1-2 km during the week of 14-21 October.
Information Contacts: V. Kirianov, IVGG.
Fumarolic activity from central crater
Seismicity was at background levels from mid-December into early January. During 4-6 January, a slight increase in seismic activity (16 events) was recorded at the volcano, but seismicity had returned to background levels (2-3 events/day) by mid-month. Seismicity was again above background in late January through mid-February. Strong fumarolic activity continued from the summit lava flow in the central crater. Similar activity was noted in May 1992, and in April, August, September, and October 1993.
Information Contacts: V. Kirianov, IVGG.
Increased seismicity and a higher steam plume
On 7 March the Institute of Volcanic Geology and Geochemistry (IVGG) reported a noteworthy increase in seismicity beneath Avachinsky and an increase in the height of the steam plume to ~100 m above the volcano. The steam plume suggested a possible increase in heat flux. The IVGG reported that the possibility of an eruption within the next few weeks to months has increased significantly. Elevated seismicity was previously reported in late 1993 and early 1994 (BGVN 19:01).

Normal seismic activity and degassing
Seismicity remained slightly above or at normal levels in June and the first half of July. Normal fumarolic activity was seen above the crater. Regular reports from KVERT (via AVO) resumed in June after funding problems in Russia halted communications in December 1994 (BGVN 19:11).

Normal seismic and fumarolic activity
Seismicity was about at background level during September, October, and November. Normal fumarolic emissions were observed above the crater.
Information Contacts: Tom Miller, Alaska Volcano Observatory (AVO); Vladimir Kirianov, Kamchatka Volcanic Eruptions Response Team (KVERT), Institute of Volcanic Geology and Geochemistry, Russia.
Fumarolic plume on 22 December
Seismicity continued at normal background levels during November 1996-December 1997. On 22 December, a fumarolic plume rose ~200 m above the crater.
Information Contacts: Vladimir Kirianov, Kamchatka Volcanic Eruptions Response Team (KVERT), Institute of Volcanic Geology and Geochemistry, Russia; Tom Miller, Alaska Volcano Observatory (AVO).
Distinct change in seismic activity
A distinct change in seismic activity began on 3 December. About 120 shallow events of very low magnitude were recorded during 3-6 December. The only days during the episode when observation was not obscured by cloud were 1 and 3-6 December, but no plumes were seen those days.

Modest October steam plumes reach 10 km long; minor ash eruption 5 October
Seismic activity increased at Avachinsky during early December 1998 (BGVN 23:11). After that, seismicity stayed mostly at background levels until 25 August 2001, when it increased slightly, and was variable through at least October.
On 31 August, three earthquakes were registered, M 1.7, 2.2, and 2.6. On 20 September an M 1.7 earthquake occurred. On 21 September from 1705 until 1721, a series of earthquakes within the volcano's edifice was recorded, including an M 2.5 event at a depth of ~4 km. On 22 September at 0500 UTC, a 3-pixel thermal anomaly was clearly seen in an AVHRR image of Avachinsky.
At 0750 on 5 October, with an accompanying M 1.5 earthquake, a small explosion lofted ash to less than 1 km above the crater with minor ash falling on the SE flank. Around 19 October a series of weak local earthquakes (~ 50 events of M 0.5-1.5) was registered within 24 hours in the edifice at a depth of ~700 m beneath the summit.
Weak fumarolic activity was observed during 20, 23, 26, and 28 September, and 2-4, 10, 11, 16, and 17 October. In contrast, on 6 October fumarolic activity was observed over the entire crater. Small mudflows down the SE flank were visible in late September after every snowfall, presumably due to strong thermal activity of a fumarole on the SE crater rim. Gas-and-steam plumes were observed several times during September and October 2001 (figure 2 and table 1) when clouds did not obscure the volcano.

13 Oct 2001 | 1130 | Extending 10 km E. |
13 Oct 2001 | 2000 | Extending 10 km E. |
20 Oct 2001 | 1430-1930 | Rising ~1 km above the crater; extending 20 km SE. |
21-22 Oct 2001 | -- | Rising 50-200 m above the crater and extending SE, E, and NE. |
A band-6 satellite image on 2 October showed a broad area of warm ground that appeared to follow the rim of the crater, with a small area in the center of the crater. Band-7 data on 2 October showed hotter areas in the SE and SW parts of the crater, and possibly on the N side. On 5 October, the Concern Color Code was increased from Green (volcano is dormant; normal seismicity and fumarolic activity) to Yellow (volcano is restless; eruption may occur). A large, elongate cloud was recorded extending to the SE from the volcano at 1830 on 8 October.
The last explosive eruption at Avachinsky occurred in 1991 and lasted 6 days. The eruption began with two ash explosions directed SW toward Petropavlovsk, and covered the town with an ash layer a few millimeters thick. Effusion of lava began 28 hours later. Further explosive activity occurred simultaneously with the lava emission. As a result of the eruption, a lava plug filled the entire crater.
The Kamchatka Volcanic Eruptions Response Team (KVERT) speculated that the recent activity at Avachinsky could indicate the occurrence of a scenario similar to the eruptions in the years 1737 and 1827. Present activity could lead to a large eruption accompanied by directed blasts with voluminous tephra, debris avalanches, and mudflows. Or, gradual damage of the plug might occur by various means, including earthquakes, small explosive discharges, mudflows, etc. Both scenarios could pose a potential hazard to nearby farm cottages (dachas), the Radyugina settlement, and Petropavlovsk-Kamchatsky city.

Shallow earthquakes in 2005; plume in 2008
This report discusses Avachinsky in 2001-2010. Following lava flows emitted in 1991 (BGVN 16:12), Avachinsky generated near-daily fumarolic plumes and generally low (background) seismicity (figure 3). The escaping gases contained sufficient sulfur to construct an area of sulfurous deposits at a prominent NW-trending crack on the SW rim of the summit crater. In 2001 a series of minor earthquakes were sometimes accompanied by gas-and-steam plumes (some with ash) (BGVN 26:11). Weak fumarolic activity and small mudflows also were observed.
By November 2001, seismic activity had declined to background levels where it apparently remained until 2005. On 8 November 2005, the Kamchatkan Volcanic Eruption Response Team (KVERT) reported that the number and energy of shallow earthquakes below Avachinsky had increased during the previous month. A weak thermal anomaly near the volcano's summit was visible on satellite imagery on 7 November. Seismicity increased significantly on 21 November, with very shallow earthquakes and several hybrid earthquakes.

During 2006 moderate fumarolic activity occurred, producing a steam plume about 700 m above crater. Seismicity was at background levels, with occasional weak seismic events at 500 m depth.
On 10 May 2008, a plume from Avachinsky rose to an altitude of 4.3 km and drifted S and E. KVERT did not detect ash by direct observation or on satellite imagery.

Copernicus Browser | The Copernicus Browser replaced the Sentinel Hub Playground browser in 2023, to provide access to Earth observation archives from the Copernicus Data Space Ecosystem, the main distribution platform for data from the EU Copernicus missions. |
MIROVA | Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity. |
MODVOLC Thermal Alerts | Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales. |
WOVOdat
Single Volcano View Temporal Evolution of Unrest Side by Side Volcanoes |
WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments. |
Volcanic Hazard Maps | The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers (or other interested parties) to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes. For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter. |
IRIS seismic stations/networks | Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Avachinsky. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice. |
UNAVCO GPS/GNSS stations | Geodetic Data Services map from UNAVCO showing the location of GPS/GNSS stations from all available networks (permanent or temporary) within a radius of 20 km from the given location of Avachinsky. Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player. |
DECADE Data | The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the Mapping Gas Emissions (MaGa) Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO2 to the atmosphere, but installing CO2 monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere. |
Large Eruptions of Avachinsky | Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA). |
EarthChem | EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS). |
