2024-02-08 21:50:11 UTC (2024-02-08) · approx. 11:50 AM UTC-10 local
On February 8, 2024 at 21:50 UTC, a magnitude 3.2 intermediate depth earthquake struck 41 km NNE of Petersville, Alaska, at a depth of 93.5 km and coordinates 62.8489°, -150.5208°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
