The Krasheninnikov volcano has erupted for the first time in over six centuries, following a powerful 8.8-magnitude earthquake that struck the Kamchatka Peninsula last Wednesday. The seismic event triggered alarms across much of the Pacific region.

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.

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