2026-08-23 21:32:14 UTC (1 day ago) · approx. 9:32 AM UTC-12 local
On August 23, 2026 at 21:32 UTC, a magnitude 3.2 intermediate depth earthquake struck 32 km SW of Adak, Alaska, at a depth of 75.1 km and coordinates 51.6470°, -176.9260°.
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.
