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 eruption occurred after a huge earthquake struck Russia’s Far East early Wednesday, an 8.8-magnitude temblor that caused small tsunami waves in Japan and Alaska and prompted warnings for Hawaii, North and Central America and Pacific islands south toward New Zealand.

The Krasheninnikov Volcano erupted on Sunday, Aug. 3, marking the volcano's first eruption in 600 years. The eruption may be linked to the massive earthquake that hit Russia less than a week earlier and caused tsunami warnings in multiple countries.
