Klyuchevskaya Sopka volcano erupts in Russia following Kamchatka earthquake, the sixth strongest recorded

The Klyuchevskaya Sopka volcano on Russia's Kamchatka Peninsula erupted hours after a powerful earthquake struck the region. The earthquake, with a magnitude between 8.7 and 8.8, was the strongest to hit Kamchatka since 1952 and triggered tsunami warnings across Russia, Japan, the U.S., and nearby Pacific countries.

According to the Kamchatka branch of the Russian Academy of Sciences (RAS) Geophysical Service, the eruption began shortly after the quake. Scientists observed incandescent lava flowing down the volcano's western slope, accompanied by intense explosions and a bright glow illuminating the summit crater. The eruption also sent ash plumes rising up to three kilometers above the volcano's summit during daylight hours.

Klyuchevskaya Sopka volcano

Klyuchevskaya Sopka, standing at 4,850 meters, is Eurasia's highest active volcano and one of the most active in the world. It features a symmetrical cone with a summit crater about 700 meters wide, surrounded by approximately 80 secondary craters and cinder cones. The volcano is situated roughly 30 kilometers from the settlement of Klyuchi, home to about 4,500 residents.


Scientists had been monitoring increased volcanic activity before the eruption, with the crater filling with lava and emitting ash plumes for several weeks. This heightened activity was expected to culminate in an eruption. The recent earthquake appears to have triggered or intensified the eruption process.

Earthquake: Sixth strongest

The 8.8 magnitude earthquake ranks the sixth strongest ever recorded globally. It joins notable events of similar magnitude including the 2010 Chile earthquake and historic quakes in Ecuador and Colombia from 1906. This seismic event is the largest in Russia since the catastrophic 9.0 quake in Kamchatka in 1952 and the strongest worldwide since the 2011 Tōhoku earthquake in Japan.

The large earthquake also generated tsunami waves that traveled across the Pacific, prompting evacuations and emergency alerts even as far as Hawaii and New Zealand. Authorities are closely monitoring both the volcanic activity and seismic aftershocks, which continue to affect the region.

Kamchatka, often called the "land of fire and ice," hosts around 300 volcanoes, with 29 currently active, making it one of the most volcanically and seismically active areas on Earth.
