M3.5 Earthquake 63 km S of Kivalina, Alaska

Shaking Ground: Moderate Earthquake Felt Across Anchorage

A noticeable tremor rattled Anchorage and surrounding communities this morning as a 3.5 magnitude earthquake struck just 63 kilometers southwest of Kivalina, Alaska. The U.S. Geological Survey reported the quake at 7:12 AM AKDT, with the epicenter located offshore and a shallow depth of just 6 miles – meaning the shaking was felt intensely. Residents across Anchorage, from the heart of downtown to the Matanuska Valley, reported feeling a jolt, with some describing it as a strong rolling motion.

What This Means for Anchorage

While thankfully, there have been no reports of damage or injuries at this time, this earthquake serves as a potent reminder of Alaska’s seismic activity. The proximity of the epicenter to Kivalina, a remote village on the northwest coast, highlights the vulnerability of coastal communities to these events. Even a moderate quake can disrupt daily life, causing anxiety and prompting a review of preparedness measures. For many Anchorage residents, the feeling of shaking is a stark contrast to the relative stability we often experience, and it’s a good opportunity to consider how we can better prepare for future events.

Local Context

Alaska is a geologically active state, sitting along the Pacific Ring of Fire where the North American and Pacific tectonic plates meet. This constant movement generates frequent earthquakes and volcanic activity. The Aleutian Islands, just west of Anchorage, are a major source of seismic energy, and the proximity of Kivalina to the Bristol Bay region underscores the importance of subsistence fishing and hunting for many Alaska Native communities – activities that can be impacted by ground instability. Furthermore, our state’s reliance on the military, with Joint Base Elmendorf-Richardson a significant presence in Anchorage, necessitates robust earthquake preparedness protocols. And, of course, for many Alaskans, the outdoors – hiking in Chugach State Park, fishing in Turnagain Arm – are integral to our lives, making earthquake awareness a vital part of our safety planning.

What to Know

If you felt the shaking, it’s a good idea to check on family and neighbors, especially those who may be vulnerable. The Alaska Division of Homeland Security and Emergency Management has resources available on their website (dhsem.Alaska.gov) to help you create a personal earthquake preparedness plan. Don’t forget to secure loose objects around your home and familiarize yourself with the “Drop, Cover, and Hold On” technique.

Let’s look out for one another and remember that we’re all part of this resilient community here in Anchorage.
