An earthquake of magnitude 2.5 occurred early afternoon on Monday, October 20th, 2025, at 2:46 pm local time near Rennes, Ille-et-Vilaine, Bretagne, France, as reported by France's Réseau National de Surveillance Sismique (RéNaSS).According to preliminary data, the quake was located at a very shallow depth of 5. 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.A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 2.6 earthquake.Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Chateaugiron (pop. 6,300) located 2 km from the epicenter, Châteaugiron (pop. 6,300) 2 km away, Noyal-sur-Vilaine (pop. 4,800) 6 km away, Vern-sur-Seiche (pop. 8,100) 7 km away, Chantepie (pop. 7,600) 8 km away, Cesson-Sevigne (pop. 16,200) 9 km away, and Rennes (pop. 220,500) 13 km away. In Vitre (pop. 17,300, 24 km away), and Fougeres (pop. 23,700, 40 km away), the quake was probably not felt.Earthquake data: Date & time: Oct 20, 2025 02:46 pm (Paris time) local time (20 Oct 2025 12:46 GMT)Magnitude: 2.5Depth: 5.00 kmEpicenter latitude / longitude: 48.06°N / 1.51°W (Ille-et-Vilaine, Bretagne, France)Primary data source: RENASS
