On November 8, 2024 at 20:05 UTC, a magnitude 3.5 intermediate depth earthquake struck 62 km NW of Ninilchik, Alaska, at a depth of 103.3 km and coordinates 60.4260°, -152.5163°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
