The activity of the volcano has intensified last night.

A certain amount of ash has been occurring in an increasingly gas-steam-rich plume, extending about 65 km to the northeast of the volcano. The latest Sentinel-2 satellite image confirmed increased emitting emissions. This may hint a new batch of magma injection inside the volcano’s main conduit that is being fragmented into fine-ash particles.

Strombolian activity continues within the summit vent, characterized by minor lava fountains that have been building the growing spatter cone and also supplying lava flows alternately along the southeastern Apakhonchich and the southern Kozyrevsky chutes. Glowing lava spatter is constantly being ejected to approx. height of 100-200 meters above the crater.
