On July 10, 2020 at 23:32 UTC, a magnitude 4.1 shallow crustal earthquake struck 73 km WSW of Kíssamos, Greece, at a depth of 36.4 km and coordinates 35.3270°, 22.8717°.

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.
