Among the active volcanic eruptions was the Krasheninnikov volcano, a previously at least 400-year-dormant volcano.

Last week, a massive magnitude-8.8 earthquake struck off Russia's Kamchatka Peninsula, sparking tsunami warnings as far away as French Polynesia and Chile.

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