2026-07-14 17:30:31 UTC (4 hours ago) · approx. 7:30 AM UTC-10 local
On July 14, 2026 at 17:30 UTC, a magnitude 3.0 shallow crustal earthquake struck 188 km SE of Chignik, Alaska, at a depth of 10.6 km and coordinates 55.0060°, -156.4620°.
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.
