2022-08-05 15:17:39 UTC (2022-08-05) · approx. 5:17 AM UTC-10 local
On August 5, 2022 at 15:17 UTC, a magnitude 2.6 shallow crustal earthquake struck 31 km W of Ester, Alaska, at a depth of 16.9 km and coordinates 64.8866°, -148.6632°.
Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 120 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 37 m — a useful intuition for the size of the slip patch on the fault.
