2022-05-26 23:27:30 UTC (2022-05-26) · approx. 1:27 PM UTC-10 local
On May 26, 2022 at 23:27 UTC, a magnitude 3.0 intermediate depth earthquake struck 42 km ESE of Pedro Bay, Alaska, at a depth of 113.6 km and coordinates 59.6820°, -153.3794°.
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.
