On July 28, 2022 at 17:12 UTC, a magnitude 4.2 shallow crustal earthquake struck 55 km S of Whites City, New Mexico, at a depth of 7.2 km and coordinates 31.6744°, -104.3833°. The earthquake was reported felt by 2 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.6 (moderate). The nearest populated place is Mentone (population 19).

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
