Advisory Issued and Later Lifted in Alaska
On September 18, 2025, a powerful magnitude 7.8 earthquake struck near Russia’s Kamchatka Peninsula, triggering a tsunami advisory for parts of Alaska. The quake occurred at 11:58 a.m. Pacific Time, roughly 75 miles east of Petropavlovsk-Kamchatsky, at a shallow depth of six miles. The National Tsunami Warning Center initially warned coastal areas of the western Aleutian Islands, from Amchitka Pass to Attu. Officials later canceled the advisory after no notable tsunami waves were detected.
Monitoring Continues in California and Hawaii
Even with Alaska’s advisory lifted, authorities in California and Hawaii are keeping a close watch. The U.S. Tsunami Warning Center confirmed that the quake poses no immediate threat to the continental U.S. or Hawaiian islands, but residents are encouraged to follow updates from official sources and remain alert to any new developments.
Ongoing Seismic Observations
Agencies including NOAA continue to track seismic activity in the Kamchatka region. While the immediate danger has passed, experts stress the importance of preparedness in coastal communities, reminding residents to stay informed and ready to respond to potential future events.
