2024-02-22 21:51:01 UTC (2024-02-22) · approx. 11:51 AM UTC-10 local
On February 22, 2024 at 21:51 UTC, a magnitude 3.2 shallow crustal earthquake struck 31 km SSE of Skwentna, Alaska, at a depth of 68.6 km and coordinates 61.7180°, -151.2573°.
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.
