On December 6, 2025 at 20:48 UTC, a magnitude 4.8 shallow crustal earthquake struck 7 km WNW of Kalávryta, Greece, at a depth of 15.9 km and coordinates 38.0628°, 22.0416°. This earthquake was detected by 54 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 356, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
