On May 4, 2026 at 21:32 UTC, a magnitude 2.7 shallow crustal earthquake struck 6 km WNW of Carleton, Michigan, at a depth of 6.8 km and coordinates 42.0715°, -83.4652°. This earthquake was detected by 31 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 195, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 169 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 44 m — a useful intuition for the size of the slip patch on the fault.
