2024-05-20 23:24:49 UTC (2024-05-20) · approx. 1:24 PM UTC-10 local
On May 20, 2024 at 23:24 UTC, a magnitude 3.0 intermediate depth earthquake struck 74 km SE of Ugashik, Alaska, at a depth of 70.9 km and coordinates 57.1292°, -156.3763°.
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.
