Geological summary
The Karpinsky Group on southern Paramushir Island in the Kuril Islands consists of three Holocene andesitic volcanic centers at the southern end of the Karpinsky Ridge. A postulated caldera is thought to have been primarily excavated by glaciers (Gorshkov, 1970). The NE cone has a crater breached to the NW that contains a small arcuate cone and a vigorous fumarole along the NE crater wall. A lava flow originating from the cone traveled 7 km to the SE. The southern cone forms the high point of the massif and fed lava flows to the SE and W. The NW cone displays hot springs and cones that occasionally eject liquid sulfur. Dark-colored gases were observed rising from the fumarolic area following a tectonic earthquake in November 1952 (Gorshkov, 1970). No confirmed eruptions have been observed, and no lava flows have been dated.
From Wikipedia
The Karpinsky Group is a volcanic group located at the southern end of Paramushir Island, Kuril Islands, Russia. The group is capped by two gently sloping cones rising to a height of 1,326 m. They are composed of andesites and andesite-basalts. In the two craters there are fumaroles and fountains of liquid sulfur. The last major, and only historic, eruption was in 1952. The sides of the volcanoes have been heavily glaciated leaving a number of cirques which were initially thought to be eroded craters. The volcanoes were named after the geologist Aleksandr Petrovich Karpinsky.
