2026-07-26 15:02:39 UTC (1 hour ago) · approx. 6:02 AM UTC-9 local
On July 26, 2026 at 15:02 UTC, a magnitude 3.0 shallow crustal earthquake struck 126 km E of Chalkyitsik, Alaska, at a depth of 10.0 km and coordinates 66.6451°, -140.8743°.
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.
