M3.3 Earthquake 203 km SE of Perryville, Alaska — December 24, 2023
2023-12-24 22:54:37 UTC (2023-12-24) · approx. 12:54 PM UTC-10 local
On December 24, 2023 at 22:54 UTC, a magnitude 3.3 shallow crustal earthquake struck 203 km SE of Perryville, Alaska, at a depth of 2.9 km and coordinates 54.6627°, -156.7964°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
