The Shiveluch volcano, in Russia's far-eastern Kamchatka territory erupted on Sunday morning for the fourth time in the past week, the Kamchatka Volcanic Eruption Response Team (KVERT) announced on its website.
"Satellite data shows ash plumes drifted about 225 km to the north-east of the volcano."
A plume of ash over seven kilometers tall rose as a result of the eruption, leading scientists to issue a warning for aircraft. The scientists also issued an ash alert for Kamchatka's residents, advising them to stay indoors and and stock up on food and water.
The volcano is one of five currently erupting or restless in Kamchatka, with the others being Zhupanovsky, Klyuchevsoy, Karmysky and Bezymianny.
Kamchatka, part of the Pacific Ring of Fire, is known for its active volcanoes, and Shiveluch, one of the region's biggest, has been erupting since 2009.
