2024-11-22 15:10:41 UTC (2024-11-22) · approx. 5:10 AM UTC-10 local
On November 22, 2024 at 15:10 UTC, a magnitude 3.1 shallow crustal earthquake struck 282 km SE of Chiniak, Alaska, at a depth of 10.0 km and coordinates 55.7455°, -149.1551°.
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.
