2025-05-29 21:32:55 UTC (2025-05-29) · approx. 9:32 AM UTC-12 local
On May 29, 2025 at 21:32 UTC, a magnitude 3.0 intermediate depth earthquake struck 26 km ESE of Adak, Alaska, at a depth of 75.1 km and coordinates 51.7522°, -176.3083°.
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.
