2023-05-26 19:38:21 UTC (2023-05-26) · approx. 7:38 AM UTC+12 local
On May 26, 2023 at 19:38 UTC, a magnitude 3.0 intermediate depth earthquake struck 259 km W of Adak, Alaska, at a depth of 100.4 km and coordinates 51.7933°, 179.5992°.
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.
