2026-04-26 23:12:50 UTC (2026-04-26) · approx. 2:12 PM UTC-9 local
On April 26, 2026 at 23:12 UTC, a magnitude 4.1 shallow crustal earthquake struck near Beaufort Sea, at a depth of 10.0 km and coordinates 71.1373°, -133.5668°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
