Russia’s Klyuchevskoy Volcano Begins Erupting

The Klyuchevskoy volcano on Russia’s Kamchatka Peninsula has begun erupting, believed to be triggered by a recent strong earthquake off the coast of the peninsula.

According to reports, lava from this, the largest active volcano in the Northern Hemisphere, has already started flowing from the mountain.

The Joint Geophysical Service of the Russian Academy of Sciences announced on Telegram: “High-temperature lava flow has been detected on the western slope of the volcano, with a bright glow visible at the summit, accompanied by explosion sounds.”

Klyuchevskoy volcano is located on Russia's Far East Kamchatka Peninsula and stands at an altitude of 4,750 meters (15,584 feet). Its last eruption was in 2023.

According to the Kamchatka Branch of the Russian Academy of Sciences Geophysical Service, local observers have reported obvious lava flow and explosion phenomena on the west side of the volcano. Scientists had already predicted a possible eruption weeks ago, noting that lava continued to accumulate in the crater and volcanic ash was being emitted.

Kamchatka is often called the “Land of Ice and Fire” and is one of the most seismically and volcanically active regions in the world. According to NASA’s Earth Observatory, there are about 300 volcanoes on the peninsula, of which 29 are still active.
