Scientists have warned that a string of volcanic eruptions along the volatile 'Ring of Fire' could have been caused by an enormous earthquake in Russia.

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

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.
