On April 10, 2022 at 18:10 UTC, a magnitude 4.7 intermediate depth earthquake struck in the Mariana Islands region, at a depth of 234.7 km and coordinates 21.5871°, 143.6909°.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
