2022-03-24 19:51:21 UTC (2022-03-24) · approx. 9:51 AM UTC-10 local
On March 24, 2022 at 19:51 UTC, a magnitude 3.0 intermediate depth earthquake struck 30 km NNE of Petersville, Alaska, at a depth of 80.0 km and coordinates 62.7583°, -150.6283°.
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.
