We have reviewed a magnitude 6.0 event that occurred at 08:11 AM AK time, northwest of Anchorage and at 43 miles depth.
This event was felt widely throughout south-central Alaska, and as far as Fairbanks.

What’s Shaking Alaska?! Welcome to your weekly seismic update from across the state, brought to you by the Alaska Earthquake Center, where we monitor ground shaking 24-7. It was a relatively quiet week with 400 minor earthquakes, only 3 of which were felt, and the largest was a magnitude 4.4 south of Chignik on November 12.
This week the Earthquake Center is undergoing a massive transition which most people will not even notice. For the past year and a half we have been building an entirely new system for how we manage and analyze earthquake data.
Our goal has been to increase our reliability and position ourselves for new technologies, particularly around artificial intelligence.
Reliability is especially important, since we strive to remain operational when telecommunications are compromised during large earthquakes and tsunamis. Our new system helps address this by running in duplicate both at the center and in a cloud platform out-of-state.
Our AI components remain in development. But we have adopted software that makes it far easier to transition experimental research techniques into operations. These steps will lead to better understanding of major faults, more accurate seismic hazard information, and it is an important step toward eventually delivering earthquake early warning in Alaska.

Good morning Alaska! We have reviewed a magnitude 5.4 earthquake that occurred at 9:33 am, 15 miles deep and 43 miles SW of Seward. This event was felt throughout Kenai Peninsula and south-central Alaska. For more information, or to submit a “Did You Feel It” report, please go to https://t.co/5jkxIkkkFc

We have reviewed a magnitude 4.9 earthquake that occurred at 12:03 AM AKDT about 57 miles south of Sand Point in the Alaska Peninsula, at a depth of about 11 miles (17 km).
No reports of this event being felt have been received at this time. This event is an aftershock of the July 16th M7.3 Sand Point Earthquake.

Latest update from our partners at the National Tsunami Warning Center. Alaskans in Aleutians communities still have a warning in effect. Go to https://t.co/B9WU35YNhn to find your community’s risk zone
Yesterday's magnitude 7.3 earthquake, which we have dubbed "2025 Sand Point Earthquake," has attracted a bit of media attention. This story posted today has some good overview content and a new graphic we created to show the location and context of the event and its aftershocks so far. I might edit the title to "...is raising scientific interest" (rather than red flags). https://t.co/tl3epkixJ4
We got this incredible footage of today's earthquake from a resident in Sand Point, about 50 miles from the epicenter. We are grateful to those who shared their experiences -- it allows others to understand what an earthquake is like, and be better prepared. We are also grateful that we have not heard of anyone injured from this fairly large earthquake for Alaska.
