PETROPAVLOVSK-KAMCHATSKY, November 7. /TASS/. An ash ejection up to 11 km high has been recorded at the Shiveluch volcano in Kamchatka, with the plume spreading east of the volcano, the Institute of Volcanology and Seismology of the Far East Branch of the Russian Academy of Sciences told TASS.

"The Shiveluch volcano in Kamchatka threw out ash 11 km above sea level. The ash plume stretched for 22 km to the east - northeast of the volcano," the institution said.

Shiveluch has been assigned a red aviation hazard code, which means that its activity is dangerous for the operation of engines of low-altitude aircraft.

The administration of the Ust-Kamchatsky district, where the volcano is located, told TASS that residents heard a loud sound and saw lightning over the volcano. Shiveluch, an active volcano 60,000-70,000 years old, consists of the ancient Old Shiveluch volcano, a caldera, and the active Young Shiveluch volcano. It is located about 50 kilometers from the village of Klyuchi in the Ust-Kamchatsky district and 450 kilometers from Petropavlovsk-Kamchatsky.
