On September 1, 2022 at 19:46 UTC, a magnitude 2.6 shallow crustal earthquake struck 4 km SE of Centerville, Maine, at a depth of 5.0 km and coordinates 44.6768°, -67.6344°. This earthquake was detected by 13 seismic stations with good location accuracy and was assigned a USGS significance rating of 112, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 120 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 37 m — a useful intuition for the size of the slip patch on the fault.
