2026-06-11 19:30:07 UTC (2026-06-11) · approx. 9:30 PM UTC+2 local
On June 11, 2026 at 19:30 UTC, a magnitude 4.5 shallow crustal earthquake struck 79 km S of Pýrgos, Greece, at a depth of 22.8 km and coordinates 34.2912°, 25.1067°. This earthquake was detected by 111 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, 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.
