The Global Volcanism Program has no Bulletin Reports available for Kharimkotan.

The 8 x 12 km island of Kharimkotan (also spelled Harimkotan) in the northern Kuriles consists of a stratovolcano cut by two breached depressions on the east and NW sides. These horseshoe-shaped craters were formed by slope failure, which produced debris-avalanche deposits that form large broad peninsulas on the east and NW coasts. Evidence of additional slope failures followed by plinian eruptions are found in sea cliffs of the island. Historical explosive eruptions have occurred since the early 18th century. A central cone, Severgin, was largely destroyed during the 1933 eruption, one of the largest in the Kuril Islands during historical time. Impact of a debris avalanche into the sea from the collapse of Severgin produced a tsunami that swept the island's coast and reached Onekotan and Paramushir Islands, killing two persons. A large lava dome emplaced during the 1933 eruption now fills the head of the eastern crater.

The east side of the 8 x 12 km island of Kharimkotan (also spelled Harimkotan) is cut by a large horseshoe-shaped caldera that was formed when the summit of the volcano collapsed in 1933. The dark-colored lava dome in the center of the photo was emplaced inside the breached depression at the end of the 1933 eruption. This and another horseshoe-shaped crater on the NW side of the island were formed by slope failure, which produced debris-avalanche deposits that form large broad peninsulas on the east and NW coasts.

The lava dome in the center of the photo was emplaced at the end of a major eruption that began on January 8, 1933 and destroyed the summit of Severgin volcano on Kharimkotan (Harimkotan) volcano, leaving a 1.7-km-wide breached crater open to the east. A debris avalanche resulting from the collapse of the summit reached the sea, extending the shoreline 1 km and producing a tsunami that swept the island and reached Onekotan and Paramushir Islands, causing two fatalities. Additional explosions were reported on Janaury 30 and April 14.
