An earthquake of magnitude 3.7 occurred early morning on Saturday, June 27th, 2026, at 3:43 am local time near Irakleion, Heraklion, Crete, Greece, as reported by the European-Mediterranean Seismological Centre (EMSC).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 Kandilli Oservatory and Earthquake Research Institute in Istanbul (KOERI-RETMC), which listed it as a magnitude 3.5 earthquake. Other agencies reporting the same quake include the National Observatory of Athens (NOA) at magnitude 3.7, The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 3.5, and The Seismological Laboratory of the University of Athens (UOA) at magnitude 3.6.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 Emparos (pop. 250) located 5 km from the epicenter, Kastelli (pop. 1,800) 9 km away, Arkalochori (pop. 3,500) 10 km away, and Malia (pop. 4,300) 18 km away.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Nea Alikarnassos (pop. 12,900) located 30 km from the epicenter, Irakleion (pop. 137,200) 30 km away, Agios Nikolaos (pop. 11,400) 31 km away, Gazi (pop. 12,600) 35 km away, and Ierapetra (pop. 12,400) 36 km away.Earthquake data: Date & time: Jun 27, 2026 03:43 am (Athens time) local time (27 Jun 2026 00:43 GMT)Magnitude: 3.7Depth: 5.00 kmEpicenter latitude / longitude: 35.14°N / 25.38°E (Dimos Minoa Pediada, Crete, Greece)Primary data source: EMSC
