On April 29, 2022 at 22:30 UTC, a magnitude 2.8 shallow crustal earthquake struck 1 km SSW of Peerless Park, Missouri, at a depth of 7.9 km and coordinates 38.5290°, -90.4997°. This earthquake was detected by 22 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 624, making it a moderate-impact event.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 274 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 55 m — a useful intuition for the size of the slip patch on the fault.
