2025-05-15 17:01:22 UTC (2025-05-15) · approx. 6:01 AM UTC-11 local
On May 15, 2025 at 17:01 UTC, a magnitude 3.2 shallow crustal earthquake struck 41 km SSW of Ugashik, Alaska, at a depth of 5.4 km and coordinates 57.1726°, -157.6765°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
