Felt by 13 people across nearby locations.
On July 31, 2026 at 18:55 UTC, a magnitude 3.1 shallow crustal earthquake struck 16 km SE of Miramichi, Canada, at a depth of 10.0 km and coordinates 46.9187°, -65.3542°. This earthquake was detected by 17 seismic stations with good location accuracy and was assigned a USGS significance rating of 152, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
