7.4 Russia Earthquake Triggers Brief Pacific Tsunami Alerts

A powerful 7.4-magnitude earthquake struck off Russia's Kamchatka Peninsula in July 2025, triggering tsunami warnings across the region and as far as Hawaii. The quake, located about 140-167 kilometers east of Petropavlovsk-Kamchatsky, was followed by multiple significant aftershocks, some above magnitude 6.0. Russian authorities and the U.S. Pacific Tsunami Warning Center initially issued tsunami alerts and watches, warning residents to avoid coastal areas, but these were lifted within hours after monitoring showed no significant tsunami waves. Predicted wave heights were relatively small, with up to 60 cm expected along parts of Russia's coast and less than 30 cm for Hawaii. No casualties or serious damage were reported, and officials emphasized that safety systems functioned properly despite the seismic activity. The Kamchatka Peninsula, known for frequent strong earthquakes due to tectonic plate activity, remains a high-risk seismic zone but saw no destructive tsunami from this event.
