Advisory Issued and Later Rescinded for Alaska
A magnitude 7.8 earthquake struck near Russia’s Kamchatka Peninsula on September 18, 2025, triggering a tsunami advisory for Alaska’s western Aleutian Islands. 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 warned communities from Amchitka Pass to Attu, though the advisory was later canceled after no significant waves were observed.
California and Hawaii Monitoring Situation
Even with the advisory lifted in Alaska, officials in California and Hawaii continue to track the event closely. The U.S. Tsunami Warning Center confirmed there is no immediate threat to the continental U.S. or Hawaii, but residents are urged to follow official updates and remain prepared for any changes.
Ongoing Seismic Surveillance
Agencies including NOAA continue monitoring seismic activity in the Kamchatka region. Experts emphasize that coastal communities should maintain awareness and preparedness, as the risk of future earthquakes and tsunamis remains.
