2026-08-13 07:20:53 UTC (36 min ago) · approx. 10:20 PM UTC-9 local
On August 13, 2026 at 07:20 UTC, a magnitude 3.0 shallow crustal earthquake struck 131 km SW of Yakutat, Alaska, at a depth of 5.0 km and coordinates 58.8420°, -141.5650°.
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.
