On December 28, 2022 at 12:24 UTC, a magnitude 5.0 shallow crustal earthquake struck 5 km E of Psachná, Greece, at a depth of 10.3 km and coordinates 38.5814°, 23.7093°. This earthquake was detected by 156 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 410, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.

Has Greece had earthquakes this big before?

The largest recorded earthquake in Greece was the M8.5 Crete earthquake of June 29, 1303. Today's magnitude 5.0 event is significantly smaller than that historical record.
