Overview

Severny Cherpuk (South Cherpuk) and Yuzhny Cherpuk (North Cherpuk) are two cinder cones SW of Ichinsky volcano that comprise the largest monogenetic volcanoes of the Sredinny Range. Severny Cherpuk, 21 km SW of Ichinsky, is a double cone that fed 1. 8 km3 lava flows down both sides of the range to the NW and SE.

A narrow tongue of the SE flow diverted an additional 10 km S, for a total distance of 22 km. Yuzhny Cherpuk, 11 km SSW of Ichinsky, produced a 1. 7 km3 lava flow that traveled 18 km S and then SE.

The flow descended to 640 m elevation and dammed tributaries of the Ketachan River, producing three lakes. The two cones are sometimes considered to be satellitic cones to Ichinsky, but Pevzner et al. (2000) noted petrological distinctions that suggest an independent origin.

Unpublished radiocarbon ages revise those in Pevzner et al. (2000) and indicate that both cones were formed about 6,500 years ago.

    About the Photo

    The Yuzhny Cherpuk cinder cone (left-center horizon) and its andesitic lava flow are located 11 km SSW from Ichinsky volcano. The fresh-looking lava flow was erupted about 6,500 years ago and traveled 18 km. Severny Cherpuk (South Cherpuk) and Yuzhny Cherpuk (North Cherpuk) are two cinder cones SW of Ichinsky that comprise the largest monogenetic volcanoes of the Sredinny Range. Severny Cherpuk, 21 km SW of Ichinsky, is a double cone that was constructed along the crest of the Sredinny Range.
