2026-05-27 19:56:36 UTC (1 hour ago) · approx. 9:56 AM UTC-10 local
On May 27, 2026 at 19:56 UTC, a magnitude 2.3 shallow crustal earthquake struck 2 km NNW of Tanaina, Alaska, at a depth of 21.7 km and coordinates 61.6520°, -149.4430°.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 42.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
