Greece was shaken near Gaitanion, Zákynthos, Ionian Islands, by an earthquake of magnitude 5.2 only 3 minutes ago, the European-Mediterranean Seismological Centre (EMSC) reported.
The quake hit at a shallow depth of 11. km beneath the epicenter near Gaitanion, Zákynthos, Ionian Islands, Greece, early morning on Tuesday, December 16th, 2025, at 1:41 am local time. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) which listed the quake at magnitude 4.9. Other agencies reporting the same quake include the German Research Centre for Geosciences (GFZ) at magnitude 5.2, and The Seismological Laboratory of the University of Athens (UOA) at magnitude 5.0.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Gaitanion (pop. 1,900) located 74 km from the epicenter, Zakynthos (pop. 11,500) 75 km away, Argostoli
