On December 12, 2021 at 17:52 UTC, a magnitude 3.0 shallow crustal earthquake struck 2 km E of Manchester, Ohio, at a depth of 14.5 km and coordinates 38.6910°, -83.5815°. This earthquake was detected by 18 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 352, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 548 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 75 m — a useful intuition for the size of the slip patch on the fault.
