2026-03-16 06:46:22 UTC (2026-03-16) · approx. 8:46 AM UTC+2 local
On March 16, 2026 at 06:46 UTC, a magnitude 4.9 shallow crustal earthquake struck 123 km S of Pýrgos, Greece, at a depth of 35.0 km and coordinates 33.8969°, 25.2847°. This earthquake was detected by 144 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
