2024-12-13 20:04:38 UTC (2024-12-13) · approx. 11:04 AM UTC-9 local
On December 13, 2024 at 20:04 UTC, a magnitude 3.2 shallow crustal earthquake struck 37 km NW of Mosquito Lake, Alaska, at a depth of 18.7 km and coordinates 59.8021°, -136.4660°.
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.
