Chachadake volcano in northern Kunashir Island contains a smaller summit cone (center) that was constructed within a 2.1 x 2.4 km caldera. It contains recent lava flows that cover much of the SW caldera floor and also flowed over the rim, extending to the lower outer flank of the older caldera. Recent eruptions were recorded in 1812 and 1973.
