2025-07-26 22:52:49 UTC (2025-07-26) · approx. 12:52 PM UTC-10 local
On July 26, 2025 at 22:52 UTC, a magnitude 2.6 shallow crustal earthquake struck 19 km SE of Kasilof, Alaska, at a depth of 62.1 km and coordinates 60.2109°, -151.0392°.
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.
