|Stokap volcano is a large stratovolcano, on top of which there are up to 8 - 10 domes, cones and craters, some of which are largely destroyed by explosions and erosion. Numerous lava flows poured from these centers, occupying the entire width of the Island from the Pacific Ocean to the Sea of Okhotsk over 16 km and an area of 135 square kilometers. The lavas of the Stokap volcano are composed of andesites and andesite basalts.
