On May 19, 2021 at 23:56 UTC, a magnitude 2.8 shallow crustal earthquake struck 2 km WSW of Gabbs, Nevada, at a depth of 11.1 km and coordinates 38.8577°, -117.9516°.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 239 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 52 m — a useful intuition for the size of the slip patch on the fault.
