Kharimkotan volcanoKharimkotan (also spelled Harimkotan) volcano is a stratovolcano forming a 8 x 12 km island in the northern Kuriles. Only the upper 25% of the massive volcano rises above sea level. In its geologic past, the volcano has suffered several slope failures and created devastating debris avalanches.
The 1933 eruption was one of the largest of the Kurile Islands in historic times. It destroyed the former summit cone of the volcano
Background:Kharimkotan volcano is cut by 2 breached horseshoe-shaped depressions caused by debris avalanches from slope failure on the E and NW sides. Their related debris-avalanche deposits form large broad peninsulas on the east and NW coasts.
More evidence of slope failures followed by plinian eruptions are found in sea cliffs of the island.
1933 eruption & tsunami
The eruption was one of the largest known of the Kurile Islands. It destroyed the summit cone (Severgin cone) and caused a debris avalanche that reached the sea and produced a tsunami that devastated the island's coast and reached Onekotan and Paramushir Islands, killing two persons.
