M3.2 Earthquake near Southeastern Alaska — August 15, 2022
2022-08-15 18:06:51 UTC (2022-08-15) · approx. 9:06 AM UTC-9 local
On August 15, 2022 at 18:06 UTC, a magnitude 3.2 shallow crustal earthquake struck near Southeastern Alaska, at a depth of 13.3 km and coordinates 58.1372°, -136.7944°.
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.
