Ivao Volcano

Ivao volcano is a group of several cinder cones on Urup Island, Kurile Islands. The cones are aligned NW-SE along the Krishtofovich Ridge of SW Urup Island.
The Ivao group itself consists of 3 young cones that are less than 10,000 years old. Ivao cone at the NW end is the highest of the group and the highest peak on Urup Island.
Lake Ivao has formed as a result of damming of a valley by the SE-most cone. Krutaya Mountain is the elongated central cone. It is the vent of the most recent eruption which erupted a viscous lava flow to the east.
