2026-09-16 16:22:34 UTC (2 days ago) · approx. 6:22 AM UTC-10 local
On September 16, 2026 at 16:22 UTC, a magnitude 3.2 shallow crustal earthquake struck 202 km SE of Perryville, Alaska, at a depth of 59.6 km and coordinates 54.6910°, -156.7710°.
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.
