Kamchatka Quake Triggers Volcanic Eruption. Klyuchevskaya Sopka, the tallest active volcano in Eurasia, has erupted just hours after the massive magnitude 8.8 earthquake off Russia's eastern coast. Lava flows and ash plumes have been confirmed. More than 100 aftershocks have rattled the region since the main quake. The ground remains unstable and the situation is still escalating. We are monitoring it all closely and will have updates tonight if anything new happens. #Kamchatka #VolcanoEruption

Rockfall was recorded 9:29 AM today, Dec. 17, 2025, by seismic and visual monitors. It was generated by the detachment or "spalling" of lava from the summit crater of Mayon, according to the PHIVOLCS. “Rockfall travelled along Mi-isi Gully (south-southeast of upper slope; left of camera footage) and came to rest within a kilometer of the Mayon summit. Alert Level 1 prevails over Mayon Volcano, and avoidance of the Permanent Danger Zone is strongly advised,” the agency added. Courtesy: PHIVOLCS/F
