Felt by 15 people across nearby locations.
On January 16, 2024 at 05:20 UTC, a magnitude 4.6 shallow crustal earthquake struck 9 km WSW of Pórto Chéli, Greece, at a depth of 10.0 km and coordinates 37.2983°, 23.0379°. This earthquake was detected by 84 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 332, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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.
