ANCHORAGE, Alaska (Nov. 6, 2025) The Alaska Earthquake Center recorded around 300 seismic events across the state this past week, including a magnitude 5.4 earthquake that struck on October 30 between Seward and Homer.
Thousands of Alaskans, even those 100 miles away, reported feeling the tremor, which lasted 10 to 40 seconds depending on distance, depth, and ground type. Thankfully, there were no reports of damage following the event.
According to the Alaska Earthquake Center, magnitude five or higher quakes are not unusual for the Kenai Peninsula, which typically experiences around 10 such events each year.
The closest monitoring stations to the Oct. 30 quake are located at Bradley Lake Dam, where four seismic sensors were installed in partnership with the Alaska Energy Authority. The center’s field team had recently completed routine maintenance and upgrades at the site, ensuring accurate data collection during the quake.
Data from these seismic instruments helps engineers quickly assess the strength and style of shaking, valuable information for monitoring infrastructure safety.
