On February 7, 2022 at 23:29 UTC, a magnitude 5.2 shallow crustal earthquake struck 281 km NNE of Fais, Micronesia, at a depth of 59.3 km and coordinates 12.0418°, 141.6632°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
