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.

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

Russia’s Krasheninnikov volcano erupted for the first time in centuries on August 3, sending ash and gas nearly four miles into the atmosphere—less than 150 miles away from the epicenter of the magnitude 8.
