On March 20, 2023 at 22:54 UTC, a magnitude 2.5 shallow crustal earthquake struck 13 km SSW of Rio Grande, Ohio, at a depth of 5.5 km and coordinates 38.7377°, -82.4288°. This earthquake was detected by 12 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 100, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 m — a useful intuition for the size of the slip patch on the fault.
