2026-04-13 21:34:23 UTC (2026-04-13) · approx. 11:34 AM UTC-10 local
On April 13, 2026 at 21:34 UTC, a magnitude 2.9 intermediate depth earthquake struck 29 km W of Salamatof, Alaska, at a depth of 102.2 km and coordinates 60.6460°, -151.8550°.
Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 338 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 60 m — a useful intuition for the size of the slip patch on the fault.
