M3.2 Earthquake 229 km SE of Chiniak, Alaska — November 24, 2023
2023-11-24 23:15:39 UTC (2023-11-24) · approx. 1:15 PM UTC-10 local
On November 24, 2023 at 23:15 UTC, a magnitude 3.2 shallow crustal earthquake struck 229 km SE of Chiniak, Alaska, at a depth of 10.0 km and coordinates 56.3685°, -149.2692°.
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.
