2024-04-29 18:53:44 UTC (2024-04-29) · approx. 7:53 AM UTC-11 local
On April 29, 2024 at 18:53 UTC, a magnitude 3.0 shallow crustal earthquake struck 112 km SSW of False Pass, Alaska, at a depth of 27.1 km and coordinates 53.9021°, -163.9879°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
