2023-11-26 19:34:29 UTC (2023-11-26) · approx. 9:34 AM UTC-10 local
On November 26, 2023 at 19:34 UTC, a magnitude 3.3 intermediate depth earthquake struck 59 km SE of King Salmon, Alaska, at a depth of 148.8 km and coordinates 58.2616°, -156.0373°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
