On June 20, 2025 at 13:53 UTC, a magnitude 4.9 shallow crustal earthquake struck 49 km SW of Palaióchora, Greece, at a depth of 44.5 km and coordinates 34.8716°, 23.3565°. This earthquake was detected by 75 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 372, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
