Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Rasshua
The roughly 6.5 x 15 km Rasshua island has a volcanic edifice largely filling a caldera in the center, shown in this September 2019 Planet Labs satellite image monthly mosaic (N is at the top). The edifice comprises three main cones and the southern rim is visible south of the two lakes. Satellite image courtesy of Planet Labs Inc., 2019 (https://www.planet.com/).

The elongated 6 x 13 km island of Rasshua in the central Kuriles contains three overlapping central cones within a 6 km caldera whose eastern margin is beyond the shoreline. An eroded central cone was constructed during the late Pleistocene, along with an isolated cone near the NW coast. Two Holocene cones were built within the crater of the central cone. The westernmost forms the 956 m high point of the island and is the source of lava flows that flooded the crater floor and descended to the coast. The easternmost cone, active during historical time, is truncated by a 500-m-wide crater that is breached to the SE. This crater may have formed during a violent eruption in 1846. The only other known historical eruption produced weak explosions in 1957. Fumarolic activity continues in the eastern crater and in the saddle between the two summit cones.
