2026-07-27 01:54:00 UTC (17 hours ago) · approx. 1:54 PM UTC+12 local
On July 27, 2026 at 01:54 UTC, a magnitude 3.2 shallow crustal earthquake struck 233 km ESE of Attu Station, Alaska, at a depth of 0.0 km and coordinates 51.8670°, 176.2220°.
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.
