2024-08-13 20:25:37 UTC (2024-08-13) · approx. 9:25 AM UTC-11 local
On August 13, 2024 at 20:25 UTC, a magnitude 3.5 shallow crustal earthquake struck 81 km ESE of King Cove, Alaska, at a depth of 35.0 km and coordinates 54.6808°, -161.2355°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
