An earthquake of magnitude 3.5 occurred late at night on Wednesday, October 29th, 2025, at 11:06 pm local time near Rethymno, Crete, Greece, as reported by the National Observatory of Athens (NOA).
According to preliminary data, the quake was located at a shallow depth of 11.60 km. 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 citizen-seismograph network of RaspberryShake which listed the quake at magnitude 3.5 as well. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 3.7, The Seismological Laboratory of the University of Athens (UOA) at magnitude 3.3, and The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 3.2.
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 Gianniou (pop. 60) located 12 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Agia Galini (pop. 1,400) located 20 km from the epicenter, Tympaki (pop. 5,300) 27 km away, Violi Charaki (pop. 2,800) 33 km away, Rethymno (pop. 32,500) 34 km away, Moires (pop. 6,400) 36 km away, and Georgioupolis (pop. 2,500) 39 km away. In Chania (pop. 53,900, 65 km away), and Irakleion (pop. 137,200, 68 km away), the quake was probably not felt.
