2025-05-31 18:53:31 UTC (2025-05-31) · approx. 6:53 AM UTC-12 local
On May 31, 2025 at 18:53 UTC, a magnitude 3.0 intermediate depth earthquake struck 38 km ESE of Atka, Alaska, at a depth of 85.5 km and coordinates 52.0530°, -173.6857°.
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.
