2024-01-24 21:40:49 UTC (2024-01-24) · approx. 11:40 AM UTC-10 local
On January 24, 2024 at 21:40 UTC, a magnitude 3.6 intermediate depth earthquake struck 83 km ESE of King Salmon, Alaska, at a depth of 128.1 km and coordinates 58.5221°, -155.2541°.
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.
