On October 24, 2026 at 22:35 UTC, a magnitude 3.3 intermediate depth earthquake struck 52 km SSW of Cantwell, Alaska, at a depth of 76.4 km and coordinates 62.9440°, -149.2430°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
