On November 28, 2020 at 23:51 UTC, a magnitude 3.5 intermediate depth earthquake struck 67 km SE of Pope-Vannoy Landing, Alaska, at a depth of 97.9 km and coordinates 59.1514°, -153.6119°.

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.
