M3.9 Earthquake 71 km SE of Ugashik, Alaska

Shaking Ground: M3.9 Earthquake Felt Across Anchorage

A noticeable tremor rattled Anchorage residents this morning as a 3.9 magnitude earthquake struck 71 kilometers southeast of Ugashik, Alaska, at 8:17 AM AKDT. The U.S. Geological Survey reports the quake occurred at a depth of 10 kilometers, and was felt strongly across Southcentral Alaska, including in areas like Eagle River, Girdwood, and even as far north as Talkeetna.

What This Means for Anchorage

While thankfully not a major event, this earthquake serves as a potent reminder of Alaska’s seismic activity and the importance of preparedness. The shaking, though brief, likely caused some anxiety for many families, particularly those living in older homes near the Chugiak Mountains. It’s a good opportunity to review your family’s emergency plan – ensuring you have a go-bag stocked with essentials, know your evacuation routes (especially important near the Turnagain Arm), and understand how to shut off utilities. This event also highlights the potential for aftershocks, which are common following earthquakes of this magnitude, so staying informed through local news and the USGS website is crucial.

Local Context

Alaska’s location along the Pacific Ring of Fire – a zone of intense volcanic and seismic activity – means we experience earthquakes regularly. Ugashik, a remote village in the Bristol Bay region, is a significant source of these events, often felt as a distant rumble across the state. Our reliance on subsistence fishing and hunting, deeply rooted in Alaska Native traditions and passed down through generations, connects us to the land and its unpredictable forces. The military presence at Joint Base Elmendorf-Richardson (JBER) also contributes to the region’s seismic monitoring, and the rugged terrain of the Chugach Mountains can amplify ground shaking. For many Anchorage residents, the thought of a larger earthquake is a familiar concern, one that’s woven into the fabric of life in the Last Frontier.

What to Know

You can monitor aftershocks and earthquake updates in real-time through the USGS website: [https://earthquake.usgs.gov/](https://earthquake.usgs.gov/). The Anchorage Police Department and Anchorage Emergency Management are also excellent resources for information and guidance. If you experience damage to your property, please report it to your insurance company and local authorities.

Anchorage residents, let’s take a moment to check in with our neighbors and ensure everyone is safe and accounted for. We’re a resilient community, and together, we’ll continue to navigate the natural wonders – and occasional tremors – of Alaska.
