2022-07-30 18:21:55 UTC (2022-07-30) · approx. 8:21 AM UTC-10 local
On July 30, 2022 at 18:21 UTC, a magnitude 2.4 shallow crustal earthquake struck 39 km NNW of Valdez, Alaska, at a depth of 26.7 km and coordinates 61.4702°, -146.5331°.
Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 60.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 27 m — a useful intuition for the size of the slip patch on the fault.
