Klyuchevskoy volcano (Kamchatka): lava flow and a beautiful steam ring
The intensity of the eruption is not particularly great, however; the lava flow is advancing only slowly and has made little progress on the steep slopes of the world's tallest stratovolcano. This suggests a rather modest effusion rate.
Intermittent small to moderate explosions, probably strombolian in type, generate occasional ash plumes that rise a few hundred meters.
