Ash from the Klyuchevskoy Volcano has fallen in the town of Klyuchi, Ust-Kamchatsky district of the Kamchatka territory, the town's volcano research laboratory reports.
"There was an ashfall in Klyuchi on Sunday morning. The ash thickness was less than one millimeter," the report said.
An ash cloud pierced by lightening formed above Klyuchevskoy last Friday. "Most probably, it was a pyroclastic flow from the volcano's upper part," it noted.
Lava is pouring down along the Kozyrevsky trench, and the flow front is moving at an altitude of approximately three kilometers, the laboratory said.
The Kamchatka branch of the Russian Academy of Sciences' Geophysical Service said that the latest ash discharge from Klyuchevskoy Volcano occurred on October 11. The emissions reached the altitude of six kilometers above the sea level.
That was the fourth ash discharge from Klyuchevskoy since August 16 when the eruption began. The other two ash discharges occurred on October 1 and 10 and the ash plume reached six kilometers above the sea level.
Klyuchevskaya Sopka (Klyuchevskoy Volcano) is an active stratovolcano located in eastern Kamchatka. The 4,850-meter volcano is one of the tallest active volcanoes in Eurasia. The nearest populated areas are Klyuchi and Kozyrevsk in the Ust-Kamchatsky district situated approximately 45 kilometers away from the giant mountain.
The strongest summit eruption of the Klyuchevskoy Volcano occurred in 1994. The crater jettisoned lava to a height of 2.5 kilometers and an ash cloud stretched out for dozens of kilometers. Mud slides flowed 25-30 kilometers to the River Kamchatka. The volcano has had several eruptions since then. The previous period of activity was recorded in the fall of 2012.
