The image of the Shiveluch volcano was received in ScanEx RDC on the 1st August 2011 during the emission of ash. The image shows that the plume is propagating southward, towards Kamchatka River.
According to INTAR-TASS message Shiveluch was spewing ash up to 4700 m over the sea level within half an hour on July 27.
Shiveluch (3283 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 9 km in diameter and the active volcano Molodoy Shiveluch. At least 15 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 color.
