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. Over the past week, we recorded about 470 earthquakes. The largest earthquake was a magnitude 5.2 near McGrath on January 29th. It was a busy week—there were 6 felt events, including earthquakes near Anchorage, Fairbanks, Haines, Healy, Wales, and McGrath. A magnitude 4.3 earthquake occurred a little after 11:00pm on February 4th, about 30 miles west of Anchorage. The shaking was widely felt from Wasilla to Soldotna, with more than 1,000 people submitting felt reports. Then, just 2 minutes later, there was a magnitude 3.7 earthquake 42 miles north of Fairbanks. People reported feeling shaking in the Fairbanks area. The January 29th magnitude 5.2 earthquake occurred in a surprising location: on the Iditarod-Nixon Fault, about 9 miles west of Takotna, in western Interior Alaska. People as far as 300 miles away in Homer reported feeling shaking. Despite the Iditarod-Nixon Fault being classified as active, Wednesday’s quake is the first with a confirmed location on this fault. It verified what geologists had previously inferred, that this is a right-lateral strike-slip fault. Based on some seismic sleuthing by UAF professor Carl Tape published in 2017, two historical earthquakes, a magnitude 7.3 in 1904 and a magnitude 6.2 in 1935, were most likely from this fault. Running parallel to the Denali Fault, the Iditarod-Nixon Fault shifts horizontally when it ruptures. Just like the western Denali Fault, it accommodates rotation of southcentral Alaska driven by the subduction of the Pacific plate.

We have reviewed a magnitude 3.0 event that occurred at 03:18 PM and was 24 miles deep and 22 miles SW of Anchorage. This event was reported felt in Anchorage. The event page is available at

We have reviewed a magnitude 4.7 event that occurred at 11:15 PM on Feb 4 and was 6 miles deep and 91 miles SSE of Perryville. No reports of this event being felt have been received at this time. The event page is available at

We have reviewed a magnitude 3.6 event that occurred at 11:09 PM on February 4 and was 6 miles deep and 13 miles SE of Livengood. This event was reported felt in Fairbanks and North Pole. The event page is available at

Fairbanks-area residents, you were not dreaming it -- there was indeed a magnitude 3.7 earthquake, just 2 minutes after the one near Anchorage last night. 11:09 pm. 42 miles north of Fairbanks. ~6 miles (10 km) deep. If you felt it, go ahead and report it on the event page here: (Sorry we missed posting it last night, I think the earlier one distracted us! :)

We have reviewed a magnitude 4.3 event that occurred at 11:07 PM AKST and was 3 miles deep and 25 miles NE of Tyonek. This event was reported felt throughout Southcentral Alaska. The event page is available at

Today there have been a series of offshore earthquakes about 110 miles east of Unalaska. Starting about 7:30am, so far there have been 5 earthquakes ranging from magnitude 2.9-5.0. There have been no felt reports for these events. We are keeping an eye on this activity.

There was a magnitude 5.0 earthquake last night about 20 mi south of Little Diomede (. It was reported as felt by just 3 people, but more likely felt it. If you live in the area, you may also have just felt (7:52 pm) a magnitude 4 aftershock (. This is not uncommon, and we will keep tracking events in the area to see if they continue. In the meantime, go ahead and follow the links here to report if you felt either one!

An unexpected jolt had Takotna and McGrath residents on their toes yesterday at 7:40pm. The breaking of the Iditarod-Nixon Fork Fault left many surprised since significant seismicity hasn't occurred since 1935. Check out our latest story about this event here!

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. Over the past week, we recorded around 220 earthquakes, with 2 reported as felt. The largest was a magnitude 5.6 earthquake south of Unalaska, which was felt by residents throughout the Fox Islands. This was the same area where last week’s magnitude 5 quake occurred. Although these are both fairly large earthquakes, they’re not uncommon for the Aleutian chain, which sits atop the subduction zone where the Pacific Plate moves underneath the North American plate. The significant stresses that accumulate because of the continuous plate motion have led to numerous large earthquakes in the Unalaska area. In 2012, a magnitude 6.2 shook the area, and a magnitude 6.5 in 2009 was followed by a vigorous aftershock sequence. In August through September of 2024, there was an earthquake swarm in the region, with multiple earthquakes of magnitude 3 or above. These types of magnitudes are a fact of life here in the most seismically active state! It is always good to know what to do in the event of a large earthquake, and we’re here to help you stay aware and prepared.

Our team is currently analyzing a seismic event with a magnitude of 5.3 that occurred at 7:40 near Takotna, situated west of McGrath at a depth of 5.5 miles (8 km). We're in the process of reviewing incoming data. Stay tuned for a more information later tonight and a comprehensive overview tomorrow morning.
