The Krasheninnikov volcano sent ash more than 3.7 miles into the sky, according to staff at the Kronotsky Reserve, where the volcano is located.

The overnight eruption of the Krasheninnikov Volcano in Kamchatka, its first in 600 years, may be connected to the huge earthquake that rocked Russia’s Far East last week, Russia’s RIA state news agency and scientists reported on Sunday.

The Krasheninnikov volcano’s first eruption in centuries is believed to have been triggered in part by the massive earthquake a few earlier.
