2025-10-25 19:41:27 UTC (2025-10-25) · approx. 9:41 AM UTC-10 local
On October 25, 2025 at 19:41 UTC, a magnitude 2.6 shallow crustal earthquake struck 36 km WNW of Cantwell, Alaska, at a depth of 0.1 km and coordinates 63.5540°, -149.5934°.
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.
