The east side of the 8 x 12 km island of Kharimkotan has a large horseshoe-shaped crater that formed when the summit collapsed in 1933. The dark-colored lava dome in the center of the photo grew inside the caldera towards the end of the 1933 eruption. This and another horseshoe-shaped crater on the NW side of the island were formed by flank collapse events that produced debris avalanche deposits that created broad peninsulas on the E and NW coasts.
