2024-09-15 18:22:11 UTC (2024-09-15) · approx. 7:22 AM UTC-11 local
On September 15, 2024 at 18:22 UTC, a magnitude 3.0 intermediate depth earthquake struck 26 km ENE of Nikolski, Alaska, at a depth of 84.2 km and coordinates 53.0179°, -168.4966°.
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.
