2024-11-29 19:23:40 UTC (2024-11-29) · approx. 9:23 AM UTC-10 local
On November 29, 2024 at 19:23 UTC, a magnitude 3.1 intermediate depth earthquake struck 47 km ESE of Pedro Bay, Alaska, at a depth of 106.7 km and coordinates 59.6729°, -153.2883°.
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.
