On July 19, 2024 at 23:36 UTC, a magnitude 2.1 shallow crustal earthquake struck 6 km NNE of Windsor, Maine, at a depth of 8.5 km and coordinates 44.3694°, -69.5494°. This earthquake was detected by 31 seismic stations with good location accuracy and was assigned a USGS significance rating of 87, 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.
