Chikurachki, the highest volcano on Paramushir Island, is a relatively small cone constructed on a high Pleistocene volcano.
Oxidzed scoria covering the upper part of the cone give it a distinctive red color.
Lava flows from Chikurachki form capes on the NW coast. The Tatarinov group of six volcanic centers is located immediately to the south of Chikurachki. In contrast to the frequently active Chikurachki, the Tatarinov volcanoes are extensively modified by erosion and have a more complex structure. Tephrochronology gives evidence of only one eruption in historical time from Tatarinov, although its southern cone contains a sulfur-encrusted crater with fumaroles that were active along the margin of a crater lake until 1959.
