On August 8, 2023 at 22:04 UTC, a magnitude 2.5 shallow crustal earthquake struck 6 km N of Turner, Maine, at a depth of 9.4 km and coordinates 44.3159°, -70.2573°. This earthquake was detected by 20 seismic stations with good location accuracy and was assigned a USGS significance rating of 189, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 m — a useful intuition for the size of the slip patch on the fault.
