Klyuchevskoy volcano (Kamchatka) activity update: phreatic explosions
The lava flow continues to be active on the southeastern flank of the volcano (the Apakhonchich chute). Interaction with snow and ice causes phreatic explosions at the contact with lava. Avalanches of loose lava blocks accompany this process.
According to satellite data, a gas-steam plume containing some amount of ash is extending about 54 km to the west of the volcano. Explosions are being observed at the summit crater that reached 20,000 ft (6,096 m) altitude.
