2023-03-26 18:34:55 UTC (2023-03-26) · approx. 8:34 AM UTC-10 local
On March 26, 2023 at 18:34 UTC, a magnitude 3.0 shallow crustal earthquake struck 168 km SSW of Akhiok, Alaska, at a depth of 6.0 km and coordinates 55.6014°, -155.4371°.
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.
