2024-12-30 20:59:52 UTC (2024-12-30) · approx. 10:59 AM UTC-10 local
On December 30, 2024 at 20:59 UTC, a magnitude 3.5 intermediate depth earthquake struck 60 km SW of Skwentna, Alaska, at a depth of 115.8 km and coordinates 61.5947°, -152.1825°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
