Russia’s Far East is experiencing an unusual burst of volcanic activity after a powerful magnitude-8.8 earthquake struck off the Kamchatka Peninsula on 30 July, prompting tsunami warnings throughout the Pacific. Local authorities reported waves of up to four metres and ordered coastal evacuations from Japan to Colombia before the alerts were lifted later the same day. The quake’s epicentre lay near one of the world’s most densely volcanic zones, where the Pacific and North American plates collide. Within hours of the seismic event, Klyuchevskoy—the peninsula’s 4,750-metre stratovolcano and the highest in Eurasia—sent fountains of lava down its western slope. Russia’s Geophysical Survey said the eruption remained largely confined to uninhabited terrain and did not immediately threaten communities or infrastructure, although monitoring agencies issued an orange aviation notice to caution aircraft of drifting ash. Early on 3 August, a second and more extraordinary eruption occurred when the long-dormant Krasheninnikov volcano awoke for the first time in roughly six centuries. Scientists at the Kamchatka Volcanic Eruption Response Team measured an ash column rising about 6,000 metres and again assigned an orange aviation code. The 1,856-metre cone lies some 200 kilometres northeast of Petropavlovsk-Kamchatsky; authorities said the ash cloud was moving east over the Pacific and posed no risk to populated areas. Researchers, including those cited by Russia’s RIA news agency, say the two eruptions are likely linked to stress changes triggered by last week’s mega-quake, which continues to generate aftershocks. Kamchatka hosts roughly 30 active volcanoes, and geophysicists warn that further activity cannot be ruled out. Emergency services remain on heightened alert while volcanologists study whether the region’s tectonic jolt could set off additional eruptions along the Pacific ‘Ring of Fire.’
