2025-05-24 22:27:45 UTC (2025-05-24) · approx. 10:27 AM UTC-12 local
On May 24, 2025 at 22:27 UTC, a magnitude 3.0 intermediate depth earthquake struck 18 km WNW of Atka, Alaska, at a depth of 194.4 km and coordinates 52.2840°, -174.4363°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
