What We Know: Russia’s Klyuchevskoy Volcano Awakens After Massive Pacific Quake That Prompted Global Tsunami Alerts
In the wake of one of the most powerful earthquakes recorded in the Pacific basin this century, Russia's Klyuchevskoy volcano -- the tallest active stratovolcano in Eurasia -- erupted dramatically on Wednesday, sending molten lava down its slopes and triggering widespread international concern.

Buildings were damaged, infrastructure shaken, and tsunami alerts were promptly issued as far away as Japan, Hawaii, Chile, and the west coasts of the United States and Canada.
As reports of "burning hot lava" cascading from Klyuchevskoy’s western flank emerged from Russia’s Geophysical Service, global authorities scrambled to coordinate coastal evacuations.
In Russia’s Severo-Kurilsk, a port town hit by waves exceeding 5 meters, emergency protocols were triggered and residents relocated inland. Similar scenes unfolded across Pacific territories including French Polynesia, where the Marquesas Islands faced waves of up to four meters, prompting midnight evacuations.
The eruption of Klyuchevskoy -- a mountain that stands more than 4,750 meters tall -- came just hours after the quake struck offshore, raising questions about geophysical triggers.
Scientists have long observed a correlation between seismic activity and volcanic eruptions, and Wednesday’s events offer yet another case for closer scrutiny.
Elsewhere, tsunami sirens wailed in Honolulu and evacuation alerts were issued in Guam, Japan, and parts of California.
In Ecuador, the Galápagos Islands braced for wave impact, while nations like Panama, Peru, and Colombia issued advisories for their Pacific coastlines. Even New Zealand issued warnings of "strong and unusual currents" -- though no mandatory evacuations were ordered.
Authorities across the region, from Moscow to Tokyo to Honolulu, praised the effectiveness of early warning systems. Still, despite no confirmed fatalities, infrastructure damage and minor injuries were reported across several affected zones.
A kindergarten in Kamchatka suffered damage, while thousands of air travelers faced delays as Hawaiian and Japanese airports temporarily halted operations.
In Russia, emergency management services declared a regional emergency, reinforcing shelters and coordinating aid.
The Kremlin stated that disaster systems had performed well under pressure, even as aftershocks -- some as strong as magnitude 6.9 -- continued to shake the Kamchatka seismic zone.
For residents along the Pacific Ring of Fire, Wednesday’s dual disaster -- seismic and volcanic -- served as a sobering reminder of the region's volatility.
And as climate extremes and tectonic shifts continue to converge, preparedness remains a central concern for vulnerable communities worldwide.
