2026-07-20 07:35:55 UTC (2 days ago) · approx. 8:35 PM UTC-11 local
On July 20, 2026 at 07:35 UTC, a magnitude 3.0 intermediate depth earthquake struck 33 km SW of Sand Point, Alaska, at a depth of 91.8 km and coordinates 55.1630°, -160.9290°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
