A magnitude-4.0 earthquake occurred in the early afternoon on Saturday, August 29th, 2026, at 3:32 pm local time near Rhodes, Dodecanese, South Aegean, Greece, according to the European-Mediterranean Seismological Centre (EMSC).According to preliminary data, the quake occurred at a very shallow depth of 5. km. Shallow earthquakes are felt more strongly than deeper ones because 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 the data and refine their calculations, or as other agencies issue their reports.Our monitoring service identified a second report from Italy's National Institute of Geophysics and Volcanology (INGV), which listed the quake at magnitude 4.5. Other agencies reporting the same quake include the Kandilli Oservatory and Earthquake Research Institute in Istanbul (KOERI-RETMC) at magnitude 4.2, Turkey's Disaster and Emergency Management Authority (AFAD) at magnitude 4.1, The Seismological Laboratory of the University of Athens (UOA) at magnitude 4.2, the citizen-seismograph network of RaspberryShake at magnitude 4.1, the National Observatory of Athens (NOA) at magnitude 4.0, and The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 3.8.Based on the preliminary seismic data, the quake was probably felt by many people in the epicentral area. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc. Weak shaking might have been felt in Chalki (pop. 310), located 3 km from the epicenter, Emponas (pop. 1,100), 25 km away, Archangelos (pop. 5,400), 48 km away, Symi (pop. 2,400), 49 km away, Paradeisi (pop. 2,600), 49 km away, Afantou (pop. 5,600), 53 km away, and Ialysos (pop. 11,300), 55 km away.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Rhodes (pop. 56,100), located 62 km from the epicenter, and Kos (pop. 19,200), 78 km away.Earthquake data: Date & time: Aug 29, 2026 03:32 pm (Athens time) local time (29 Aug 2026 12:32 GMT)Magnitude: 4.0Hypocenter depth: 5.00 kmEpicenter coordinates: 36.23°N / 27.58°E (South Aegean, Greece)Primary data source: EMSC
