Strong Quakes Off Kamchatka Prompt Tsunami Alerts

A series of powerful earthquakes, including one with a magnitude between 7.4 and 7.5, struck off the coast of Russia’s Kamchatka Peninsula early Sunday, with the strongest near Petropavlovsk-Kamchatsky. The quakes triggered tsunami alerts for Russia, Hawaii, Japan, and Midway Atoll, with initial warnings of possible waves up to 1 meter for the Russian coast and smaller waves elsewhere. Hawaii issued a tsunami watch that was later canceled as the threat subsided. Numerous aftershocks followed, some exceeding magnitude 6.5, prompting ongoing building inspections and heightened alert among authorities. No major damage or casualties have been reported so far. The Kamchatka region, part of the seismically active Kuril-Kamchatka trench, remains under close observation.
