Felt by 4 people across nearby locations.
On November 17, 2025 at 21:04 UTC, a magnitude 4.5 shallow crustal earthquake struck 29 km WNW of Skýros, Greece, at a depth of 10.0 km and coordinates 39.0090°, 24.2442°. This earthquake was detected by 47 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 313, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 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.
