2023-12-30 22:36:05 UTC (2023-12-30) · approx. 12:36 PM UTC-10 local
On December 30, 2023 at 22:36 UTC, a magnitude 3.4 intermediate depth earthquake struck 35 km E of Pedro Bay, Alaska, at a depth of 132.6 km and coordinates 59.8152°, -153.4729°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
