Matanuska-Susitna Borough, Alaska – A magnitude 3.6 earthquake struck northwest of Susitna on Thursday afternoon, drawing monitoring attention but no immediate reports of damage.
According to the Alaska Earthquake Center, the quake occurred at 4:30 p.m. UTC (8:30 a.m. AKDT) approximately 15 kilometers west-northwest of Susitna. The event registered at a depth of about 69.7 kilometers, classifying it as a deeper seismic event less likely to cause surface-level impacts.
Seismic activity at this depth often reduces the intensity felt at ground level, and early data shows limited community response. Initial “Did You Feel It?” reports remain low, suggesting minimal shaking was experienced in nearby populated areas, including parts of the Matanuska-Susitna Borough and areas north of Anchorage.
Alaska is one of the most seismically active regions in the world, with frequent small-to-moderate earthquakes recorded across the state. Most events of this magnitude occur without causing damage, particularly when located deep beneath the surface.
Officials continue to monitor the situation, though no advisories or alerts have been issued. Residents are encouraged to remain aware of emergency preparedness practices as part of standard guidance in earthquake-prone regions.
The event may be of interest to commuters and remote workers traveling between Susitna-area communities, though no disruptions have been reported.
