2024-10-09 21:20:48 UTC (2024-10-09) · approx. 10:20 PM UTC+1 local
On October 9, 2024 at 21:20 UTC, a magnitude 4.0 shallow crustal earthquake struck 18 km NNE of Kerasochóri, Greece, at a depth of 17.3 km and coordinates 39.1653°, 21.6988°.
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.
