2024-11-04 22:59:45 UTC (2024-11-04) · approx. 12:59 PM UTC-10 local
On November 4, 2024 at 22:59 UTC, a magnitude 3.1 intermediate depth earthquake struck 65 km N of Petersville, Alaska, at a depth of 120.4 km and coordinates 63.0851°, -150.8818°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
