2026-07-09 17:35:43 UTC (2026-07-09) · approx. 5:35 AM UTC-12 local
On July 9, 2026 at 17:35 UTC, a magnitude 3.2 shallow crustal earthquake struck 104 km SW of Adak, Alaska, at a depth of 26.9 km and coordinates 51.2352°, -177.7452°.
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.
