2024-03-27 16:31:39 UTC (2024-03-27) · approx. 5:31 AM UTC-11 local
On March 27, 2024 at 16:31 UTC, a magnitude 3.2 shallow crustal earthquake struck 154 km S of False Pass, Alaska, at a depth of 35.0 km and coordinates 53.4723°, -163.6247°.
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.
