On November 3, 2021 at 15:09 UTC, a magnitude 4.2 shallow crustal earthquake struck 54 km W of Kíssamos, Greece, at a depth of 45.9 km and coordinates 35.4949°, 23.0530°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
