Vladivostok, Aug 4: In what scientists are calling an extraordinary natural event, six volcanoes on Russia’s Kamchatka Peninsula have erupted or shown significant activity simultaneously — a rare phenomenon not witnessed in nearly three centuries.
According to Alexey Ozerov, Director of the Institute of Volcanology and Seismology of the Russian Academy of Sciences, the last time such widespread volcanic activity occurred in Kamchatka was in 1737, following a powerful magnitude-9 earthquake. He believes the recent seismic event on July 30 may have triggered the reactivation of dormant volcanic systems.
“This could be the reawakening of the region’s sleeping giants,” Ozerov told Russia’s TASS news agency.
Yury Demyanchuk, head of the volcanology station in Klyuchi village and a veteran with over 50 years of field experience in the region, described the phenomenon as unprecedented in his career. He pointed out that Krasheninnikov Volcano is erupting from both its summit and central crater — a signal of intense internal activity.
Demyanchuk added that Krasheninnikov last erupted in the 15th century, known only through geological ash deposits. “No one monitored it in the 1400s, so what we’re seeing now is truly historic,” he said.
As of Sunday, the active volcanoes include Avachinsky, Klyuchevskoy, Bezymianny, Kambalny, Karymsky, and Krasheninnikov. Klyuchevskoy is exhibiting strong summit eruptions with lava flows and strombolian activity. Bezymianny is in a weak extrusive-explosive phase, while Karymsky continues summit eruptions. Kambalny is showing rising seismic signals, indicating a possible explosive eruption with ash clouds projected up to 6 kilometers high.
Authorities have urged residents and tourists to avoid the affected areas as volcanic risk levels remain elevated. Scientists continue to monitor the region closely, calling the event a rare window into the dynamic forces shaping Earth’s crust.
