Felt by 7 people across nearby locations.
On October 30, 2020 at 15:14 UTC, a magnitude 5.3 shallow crustal earthquake struck 8 km NW of Kokkári, Greece, at a depth of 10.0 km and coordinates 37.8319°, 26.8222°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Greece, a region characterized by the Hellenic subduction zone, where the African Plate subducts northward beneath the Aegean at roughly 35 mm per year. The nearest mapped fault system is the Hellenic Trench. View all earthquakes in Greece.
