2026-05-20 20:40:14 UTC (1 hour ago) · approx. 10:40 AM UTC-10 local
On May 20, 2026 at 20:40 UTC, a magnitude 3.2 intermediate depth earthquake struck 10 km ENE of Nikolaevsk, Alaska, at a depth of 80.6 km and coordinates 59.8560°, -151.4490°.0
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
