2025-04-23 20:23:08 UTC (2025-04-23) · approx. 9:23 AM UTC-11 local
On April 23, 2025 at 20:23 UTC, a magnitude 3.2 shallow crustal earthquake struck 95 km SSE of Sand Point, Alaska, at a depth of 10.0 km and coordinates 54.5517°, -159.9063°.
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.
