The central part of the massif of the Karpinsky volcano is formed by three Late Pleistocene-Holocene volcanoes located along the edges of a large caldera-shaped depression of glacial origin (this depression was previously considered the Karpinsky volcanic caldera). Two young cones are located into the depression, one of them on the eastern slope of the Karpinsky ridge. In the summit crater of this cone is an internal cone of a horseshoe-shaped and fumaroles. A long lava flow stretches from the volcano, overlooking the coastal plain near the Sea of Okhotsk. The second young cone is located on the watershed ridge of the Karpinsky ridge, from it southeast and west flows of andesite-basaltic lava flows. The third young volcanic center - a large explosive crater on the eastern side of the depression at 1100-1200 m - is characterized by intensively acting solfatars and hot springs.
