2024-07-29 20:38:51 UTC (2024-07-29) · approx. 9:38 AM UTC-11 local
On July 29, 2024 at 20:38 UTC, a magnitude 3.6 shallow crustal earthquake struck 174 km SW of Nikolski, Alaska, at a depth of 35.0 km and coordinates 52.0497°, -170.9755°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
