|The Cherny cone forms an even strongly truncated cone with a well-defined crater with a diameter of 330 m at the summit. The inner walls of the crater look like a steep funnel with a slope angle of about 60 °; at a depth of 150 m there is a flat bottom with a diameter of 150 m. The slopes of the cone are flat, without erosion potholes.
The surface of the cone is covered with light pyroclastic, in some places lava flows are visible, heavily covered with ash at the source. A large wide lava flow descends from the crater along the western slope and reaches the shore of the Sea of Okhotsk, a number of flows flowed down the eastern slope. The longest flow, up to 3 km, descends along the northern slope. At the foot of the Cherny cone from the east, there are two side craters, from which lava flows into the ocean flowed. Currently, the Cherny cone is actively solfatory. Solfatar exits are located at the bottom and along the walls of the summit crater. A powerful, linearly elongated group of solfatars is located on the western slope at the top.
The volcano is named after the Cossack centurion Ivan Cherny, who in 1766-1769 made a detailed description of the 19 Kuril Islands he visited.
