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.

Tsunami alerts were issued for Alaska and Hawaii on Tuesday after a major, 8.8 magnitude earthquake struck off the coast of Russia, according to officials.
