2026-06-28 03:19:36 UTC (2026-06-28) · approx. 5:19 PM UTC-10 local
On June 28, 2026 at 03:19 UTC, a magnitude 2.6 shallow crustal earthquake struck 11 km S of Clam Gulch, Alaska, at a depth of 53.6 km and coordinates 60.1320°, -151.3670°.
Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 120 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 37 m — a useful intuition for the size of the slip patch on the fault.
