The lava dome remains active and produces hot avalanches on the western and eastern flanks. KVERT reports moderate seismic activity, incandescence of the volcano summit and medium to strong degassing.

Activity continues with little changes. Video data showed that the lava dome is still active and produces incandescence and hot avalanches on the western and eastern flanks. Strong and moderate gas-steam activity accompany this process. Satellite data showed a thermal anomaly over the volcano. (KVERT)

Typical eruption style: Explosive Kizimen volcano eruptions: 2010-ongoing, 1927-28, 850 (?), 700±50, 350±75, 1010 BC (?), 4050 BC (?), 4450 BC (?), 580050 BC , 6400±50 BC, 8050 BC (?) Last earthquakes nearby:
Background:Kizimen's shape is similar to Mount St. Helens before the massive 1980 eruption. The northwestern side of Kizimen volcano is cut by NE-SW-trending normal faults, which form a series of cliffs, and could be the site of a future flank collapse.The summit of Kizimen is formed by overlapping lava domes, from which blocky lava flows descend the flanks of the volcano. Kizimen is at the W end of a volcanic chain north of Kronotsky volcano. Kizimen itself was built during four eruptive cycles beginning about 12,000 years ago and lasting 2000-3500 years each, separated by large explosive eruptions about 12000, 8300 and 3000 years ago. In between those major explosive eruptions, lava domes were formed in at least 3 phases. Another large explosive eruption occurred about 1100 years ago. It produced a lateral blast and created a 1.0 x 0.7 km wide crater breached to the NE, inside which a small lava dome has grown. Before the eruption starting in 2010, the only known historic activity took place in 1927-28. |
