KAMCHATKA, RUSSIA — A volcano dormant for over six centuries violently erupted on Saturday evening, just days after an 8.8-magnitude earthquake rocked Russia’s far eastern Kamchatka Peninsula.

The Krasheninnikov volcano, located within the Kronotsky Nature Reserve, exploded to life for the first time since circa 1463, sending a massive ash plume soaring 6 kilometers (3.7 miles) into the sky, according to the Russian Institute of Volcanology and Seismology.

Aerial video captured by Artem Sheldovitsky, a mountain guide with Snow Valley tours, shows the dramatic eruption continuing into Sunday as ash blanketed parts of the nature reserve.

Volcanologist Alexey Ozerov of the Russian Academy of Sciences confirmed the eruption was likely triggered by seismic pressure caused by the record-breaking earthquake on July 30.

The Kamchatka Volcanic Eruption Response Team reported the ash plume was drifting eastward over the Pacific Ocean, with no immediate threat to populated areas.

Meanwhile, two other volcanoes, including the Kambalny volcano, are now showing signs of increased activity, prompting concerns that more eruptions could follow.

“This is a dynamic seismic event unlike anything we’ve seen in modern times,” said one researcher, adding that ashfall could disrupt air traffic and alter local ecosystems for weeks.
