Shiveluch (3,283 m) is the northernmost volcano on the peninsula, located in the northern part of the Kamchatka depression and has been recurrently erupting since 1980. This volcano started to take shape around 60-70 thousand years ago. It includes the stratovolcano Stary Shiveluch, the caldera of 9km in diameter and the active volcano Molodoy Shiveluch. At least fifteen great eruptions with the volume of juvenile pyroclastics > 0.5 cu.km are related to this volcano in the Holocene age.
The lower slopes of volcanic construction are covered with forest of stone birch and the brushwood of mountain pine. The upper layer is covered by meadows. Vegetation free lava-ash surface closer to the top is displayed on the image by contrasting pink colour.
