Klyuchevskoy volcano (Kamchatka): new activity in summit crater
On 29 December, Tokyo VAAC reported that fresh ashes were observed on the slopes of Klyuchevskoy. KVERT now changed the status level from green to yellow, as additional signs of volcanic activity have been gathered recently:
Increased seismic activity has been noted since 19 Dec. A small plume could be detected from Klyuchevskoy volcano on satellite imagery from 2 January. A thermal anomaly is visible o satellite data as well, and last, but not least, during clear weather, glow can be seen from the summit at night.
Most likely, the type of activity (for now) is mild strombolian explosions is occurring in the summit crater, a typical behavior of Klyuchevskoy volcano, one of the most active volcanoes in the world, which often has long-lasting phases of continuous activity as well.
