2023-04-05 22:03:47 UTC (2023-04-05) · approx. 10:03 AM UTC+12 local
On April 5, 2023 at 22:03 UTC, a magnitude 3.2 intermediate depth earthquake struck 233 km W of Adak, Alaska, at a depth of 97.8 km and coordinates 51.7368°, 179.9915°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
