On May 29, 2022 at 19:12 UTC, a magnitude 2.3 shallow crustal earthquake struck 16 km S of Louisa, Virginia, at a depth of 7.0 km and coordinates 37.8825°, -78.0332°. This earthquake was detected by 10 seismic stations with good location accuracy and was assigned a USGS significance rating of 86, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 41.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
