On November 23, 2020 at 15:50 UTC, a magnitude 4.6 shallow crustal earthquake struck 208 km NNE of Fais, Micronesia, at a depth of 10.0 km and coordinates 11.5426°, 141.1431°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
