2026-10-16 17:24:27 UTC (1 hour ago) · approx. 7:24 AM UTC-10 local
On October 16, 2026 at 17:24 UTC, a magnitude 3.0 shallow crustal earthquake struck 21 km SSW of Trapper Creek, Alaska, at a depth of 46.6 km and coordinates 62.1570°, -150.4520°.
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.
