Overview

The Karpinsky group on southern Paramushir Island 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 horseshoe-shaped 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 Karpinsky massif and fed lava flows to the SE and W. The NW cone displays hot springs and sulfur cones containing liquid sulfur that is occasionally ejected outward.

A minor ash ejection following an earthquake in 1952 marked the only historical eruption.

    Regional Volcanic Activity
    The Northwestern Pacific Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

    About the Photo

    The Karpinsky Group, seen here from the south, consists of three Holocene volcanic centers at the southern end of the Karpinsky Ridge in the southern part of Paramushir Island. The southern cone forms the high point of the Karpinsky massif and produced lava flows to the SE and west. The NW cone has hot springs and sulfur cones containing boiling sulfur-rich waters.
