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 Krasheninnikov Volcano, located on the Kamchatka Peninsula, released a massive ash plume reaching up to 6,000 meters (3.7 miles) into the sky, according to Russia’s emergency services ministry.

The eruption of the Krasheninnikov volcano on Sunday in Russia’s Far East came after a series of seismic events this past week on the Kamchatka peninsula.
