2024-09-29 18:48:12 UTC (2024-09-29) · approx. 8:48 AM UTC-10 local
On September 29, 2024 at 18:48 UTC, a magnitude 3.0 shallow crustal earthquake struck 113 km NNE of Arctic Village, Alaska, at a depth of 4.4 km and coordinates 69.0978°, -144.7150°.
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.
