MOSCOW, April 13. /TASS/. The Shiveluch volcano on Russia’s far eastern Kamchatka Peninsula has calmed down after three days of eruptions, but it can still eject ash plumes up to 6 km into the air, the regional office of the Russian Academy of Sciences’ Geophysical Survey said on its Telegram channel on Thursday.

"Eruptions are continuing, but they have become noticeably less intense. A further slowdown in eruption activity should be expected, but sporadic plumes of volcanic ash at a height of 5 km to 6 km may still occur," researchers warned.

Experts say they have been registering hundreds of earthquakes locally. Some surface events may have been accompanied by ash emissions reaching an altitude of up to 5 km.

"The volcano is coated in heavy clouds, so the ash cloud around it can only be assessed using satellite data," the Geophysical Survey said in a statement.

The Shiveluch volcano started erupting at 0:54 a.m. on April 11 (Moscow time: 3:54 p.m. on April 10). Three peak eruption phases were recorded. According to satellite data, at 8:30 a.m. on Tuesday (11:30 p.m. Moscow time on Monday), the ash cloud over the Shiveluch volcano reached 20 km above sea level, with the resulting ash plume covering an area ranging from 240 to 400 kilometers.

Shiveluch is one of the largest volcanoes on Kamchatka with a height of 3,283 meters. It consists of three elements: the "Old Shiveluch" stratovolcano, an ancient caldera, and the active "Young Shiveluch.".
