On December 24, 2021 at 23:59 UTC, a magnitude 4.1 shallow crustal earthquake struck 2 km WSW of Blamont, France, at a depth of 9.2 km and coordinates 47.3748°, 6.8239°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
