2024-03-28 20:09:52 UTC (2024-03-28) · approx. 10:09 AM UTC-10 local
On March 28, 2024 at 20:09 UTC, a magnitude 3.0 intermediate depth earthquake struck 54 km ESE of King Salmon, Alaska, at a depth of 142.7 km and coordinates 58.4661°, -155.8358°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
