2021-01-20 20:35:39 UTC (2021-01-20) · approx. 10:35 PM UTC+2 local
On January 20, 2021 at 20:35 UTC, a magnitude 4.0 intermediate depth earthquake struck 12 km ESE of Lárdos, Greece, at a depth of 82.4 km and coordinates 36.0381°, 28.1342°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
