Klyuchevskoy (Russia) - Report for 13 August-19 August 2026 - New Eruptive Activity — volcanic activity reported was recorded by Global Incident Tracker on Thursday, 20 August 2026 at 08:08 UTC. The event is classified as a volcanic eruption incident with a severity rating of Moderate, and was detected through GVP.
The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that a new eruption at Klyuchevskoy began with Strombolian explosions and lava fountaining at the summit crater on 15 August. The temperature of a thermal anomaly identified in satellite images began increasing at 1541. Activity continued on 16 August and at 2236 the Aviation Color Code (ACC) was raised to Yellow (the second lowest level on a four-color scale). A series of large collapses began in the Apakhonchichsky drainage on the SE flank at 2320 and lasted about 30 minutes. Ash clouds from the collapse and possible explosions rose 7-8 km (22,960-26,250 ft) a.s.l. and drifted 50 km E, though according to the Tokyo Volcanic Ash Advisory Center (VAAC) ash plumes may have risen as high as 9.1 km (30,000 ft) a.s.l. The ACC was raised to Orange at 2343. Strombolian explosions and lava fountaining continued on 17 August and col
Where this happened
The incident is located in Russia (Europe), whose capital is Moscow. Historically, Russia is most affected by wildfires, floods, earthquakes and extreme cold. You can follow every incident recorded in this country, updated live, on the Russia incident tracker.
Approximate coordinates of the reported event are 61.500°, 105.300°. The marker on the map above shows this position; for news-derived reports the location reflects the place named in media coverage and may represent a district or city rather than an exact site.
Understanding volcanic eruption events
Eruptions producing ash, lava, pyroclastic flows and lahars. Volcanic risk extends far beyond lava. Pyroclastic flows, ashfall that collapses roofs, lahars (volcanic mudflows) and aviation-grade ash clouds account for most volcanic casualties and economic damage.
How severity is rated
Global Incident Tracker rates every event on a four-step scale — Minor, Moderate, Severe and Extreme — derived from the source signal: earthquake magnitude, official GDACS alert colour, or the volume of independent media reporting for news-derived incidents. This event is currently rated Moderate. Ratings can change as more information becomes available, and a rating is a monitoring signal rather than an official government assessment.
Safety guidance for volcanic eruption situations
- Follow exclusion zones exactly — pyroclastic flows travel faster than any vehicle on local roads.
- Protect against ashfall with an N95 mask and eye protection; ash damages lungs and engines.
- Avoid river valleys and low ground downstream, where lahars concentrate.
- Clear roof ash carefully; wet ash is extremely heavy and collapses structures.
- Follow only official instructions from local authorities and emergency services — this page is a monitoring record, not an emergency alert.
Data and verification
This record was generated automatically from GVP and de-duplicated against our archive. Early reports for any incident can be revised: locations get refined, magnitudes are recalculated and impact figures change as assessments arrive. We deliberately do not publish casualty numbers unless an official source states them. The original source report is linked at the top of this page.
