On September 24, 2023 at 23:59 UTC, a magnitude 2.7 shallow crustal earthquake struck 1 km N of Charlemagne, Canada, at a depth of 5.2 km and coordinates 45.7301°, -73.4849°. This earthquake was detected by 32 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 116, 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.
