2023-03-16 23:26:50 UTC (2023-03-16) · approx. 1:26 PM UTC-10 local
On March 16, 2023 at 23:26 UTC, a magnitude 3.2 intermediate depth earthquake struck 74 km WSW of Cantwell, Alaska, at a depth of 112.7 km and coordinates 63.2182°, -150.3806°.
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.
