2026-06-24 20:10:58 UTC (2026-06-24) · approx. 8:10 AM UTC+12 local
On June 24, 2026 at 20:10 UTC, a magnitude 3.2 shallow crustal earthquake struck 226 km ESE of Attu Station, Alaska, at a depth of 10.0 km and coordinates 52.0580°, 176.2546°.
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.
