BackgroundA small andesitic stratovolcano, Kamuinupuri, was constructed beginning about 4000 years ago in the SE part of of the deep caldera lake. The latest dated eruption of the volcano was a large explosive eruption about 1000 years ago, which created a 1.2 x 1.5 km crater at the summit of Kamuinupuri.
Kamuishu is a small island in the center of Lake Mashu. It is the tip of a mostly submerged dacitic lava dome.
