On April 8, 2026 at 23:17 UTC, a magnitude 2.1 shallow crustal earthquake struck 2 km SE of Madison, Ohio, at a depth of 8.0 km and coordinates 41.7520°, -81.0320°. This earthquake was detected by 18 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 77, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 21.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 17 m — a useful intuition for the size of the slip patch on the fault.
