Details for: Moyorodake [Medvezhia]
Medvezhia, an eroded 8-km-wide caldera at the NE tip of Iturup Island, contains a complex of several cones and lava domes. Four closely spaced volcanic cones lie on an E-W line. The easternmost and highest, Medvezhii cone (upper left), lies outside the caldera, along the Pacific coast. Srednii cone (center), which has produced lava flows that reached the coast, is located immediately to the west. The slightly lower, historically active Kudriavy cone (right center) has fed youthful-looking lava flows that reach the caldera wall. Photo by T.
