A powerful 8.8-magnitude earthquake struck off the coast of Russia’s Kamchatka Peninsula early Tuesday, prompting tsunami alerts across the Pacific and leading to evacuations in multiple countries.
According to the U.S. Geological Survey, the quake occurred at a depth of roughly 20 kilometers (12.4 miles) and was located about 74 miles southeast of Petropavlovsk-Kamchatsky, a major city in Russia’s Far East. The initial magnitude was reported as 8.0 before being upgraded.
Following the quake, tsunami warnings were issued for coastal regions of Russia, Japan, Hawaii, and the U.S. West Coast. In Severo-Kurilsk, Russia, waves reached up to five meters, causing flooding in port areas and sweeping away fishing vessels.
In Japan, nearly one million residents were advised to evacuate coastal zones. Small tsunami waves were observed in areas such as Hokkaido and Iwate Prefecture. Transportation services, including trains and ferries, were suspended as a precaution, and authorities confirmed no immediate reports of major damage. Nuclear facilities, including the Fukushima Daiichi plant, reported no issues.
In Hawaii, tsunami sirens triggered evacuations from low-lying areas. Waves up to four feet were reported in parts of Honolulu, flooding some roads and prompting the temporary closure of airports and harbors. Heavy traffic was seen in Oahu and Maui as residents moved inland.
Along the U.S. West Coast, tsunami advisories were issued for regions from California to Washington. While no mandatory evacuations were ordered, residents were urged to stay away from beaches due to dangerous currents. Minor wave activity was recorded in coastal areas such as Crescent City and Humboldt Bay.
Tsunami alerts extended across the Pacific, with officials in Mexico, Chile, Ecuador, Colombia, and other coastal nations on high alert. New Zealand also monitored the threat but reported no significant impact.
Dozens of aftershocks followed, including one measuring magnitude 6.9. In Kamchatka, officials reported minor injuries and localized damage, but no large-scale devastation. Emergency teams were deployed to inspect infrastructure and assist residents.
Experts noted this earthquake is among the strongest recorded in recent years and the most powerful since the 2011 magnitude-9.0 quake off Japan’s coast, which caused a catastrophic tsunami and nuclear emergency.
Thanks to early-warning systems and rapid response protocols, officials said much of the Pacific region avoided a worst-case scenario. Monitoring continues amid ongoing seismic activity in the region.
