On July 20, 2026 at 15:26 UTC, a magnitude 2.5 shallow crustal earthquake struck 18 km WSW of Anchorage, Alaska, at a depth of 47.0 km and coordinates 61.1410°, -150.1950°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 m — a useful intuition for the size of the slip patch on the fault.
