PETROPAVLOVSK-KAMCHATSKY, November 17. /TASS/. The activity of the Klyuchevsky volcano in the Russian Far Eastern region of Kamchatka has intensified again, the local department of the Russian Academy of Sciences’ geophysical service told TASS on Thursday.

"In the morning, the Klyuchevsky volcano spewed a column of ash to six kilometers above the sea level. This was registered by satellites as the volcano was covered in clouds. Later the slopes of the volcano became visible, and we can see now how it spews steam, gas and ash to 5.5 kilometers above the sea level," the department said.

The Kamchatka Volcanic Eruption Response Team (KVERT) said earlier that the Klyuchevsky volcano spewed ash to seven kilometers above the sea level for the last time on November 3. After that, the activity of the volcano considerably decreased.

The Klyuchevskoy is the highest active volcano in Eurasia. Its height changes from 4,750 to 4,850 meters above the sea level. There are currently four active volcanoes on the territory of the Russian Far Eastern Kamchatka Krai — Klyuchevskoy, Shiveluch, Bezymyanny, and Karymsky.
