M3.2 Earthquake south of Alaska — June 24, 2023
2023-06-24 21:23:54 UTC (2023-06-24) · approx. 10:23 AM UTC-11 local
On June 24, 2023 at 21:23 UTC, a magnitude 3.2 shallow crustal earthquake struck south of Alaska, at a depth of 12.9 km and coordinates 54.7931°, -158.1599°.
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.
