The European-Mediterranean Seismological Centre (EMSC) reported a magnitude 3.9 earthquake in Greece near Chalkida, Euboea, Central Greece, only 15 minutes ago. The earthquake struck early on Saturday morning, September 19, 2026, at 1:11 am local time, at a shallow depth of 10. km. 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 reports.A second report was later issued by the Kandilli Observatory and Earthquake Research Institute in Istanbul (KOERI-RETMC), which also listed it as a magnitude 3.9 earthquake. Other agencies reporting the same quake include the Seismological Laboratory of the University of Athens (UOA), at magnitude 3.9; the Aristotle University of Thessaloniki Geophysical Lab. (AUTH), at magnitude 3.8; the National Observatory of Athens (NOA), at magnitude 4.1; and the citizen-seismograph network of RaspberryShake, at magnitude 4.1.Based on the preliminary seismic data, the quake should not have caused any significant damage but was probably felt by many people as a light vibration in the area of the epicenter. Weak shaking might have been felt in Agia Anna (pop. 820), located 9 km from the epicenter; Mantoudi (pop. 1,800), 15 km away; Limni (pop. 2,100), 21 km away; Istiaia (pop. 4,300), 26 km away; and Nea Artaki (pop. 9,500), 48 km away.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Chalkida (pop. 59,100), located 54 km from the epicenter; Volos (pop. 86,000), 65 km away; Nea Ionia (pop. 32,700), 67 km away; and Thivai (pop. 36,500), 68 km away.Earthquake data: Date & time: Sep 19, 2026 01:11 am (GMT +3) local time (18 Sep 2026 22:11 GMT)Magnitude: 3.9Hypocenter depth: 10.00 kmEpicenter coordinates: 38.93°N / 23.45°E (Central Greece, Greece)Primary data source: EMSC
