Russian volcano erupts after centuries of dormancy, spewing hot ash into sky and triggering 7.0-magnitude earthquake with tsunami warning on Kamchatka Peninsula.

A volcano on Russia's eastern Kamchatka Peninsula erupted overnight into Sunday for what scientists said is the first time in hundreds of years, days after a massive 8.8-magnitude earthquake.

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.
