On August 27, 2026 at 18:15 UTC, a magnitude 2.1 intermediate depth earthquake struck 49 km NW of Ninilchik, Alaska, at a depth of 87.3 km and coordinates 60.3960°, -152.2430°.
Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 21.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 17 m — a useful intuition for the size of the slip patch on the fault.
