A magnitude 3.9 earthquake near Oia, Kykládes, South Aegean, Greece, was reported 34 minutes ago by the National Observatory of Athens (NOA), considered the main national agency that monitors seismic activity in Greece. The earthquake occurred at a shallow depth of 10.80 km beneath the epicenter early morning on Monday, September 15th, 2025, at 6:53 am local time. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 4.4. Other agencies reporting the same quake include the United States Geological Survey at magnitude 4.4, the German Research Centre for Geosciences (GFZ) at magnitude 4.3, the Kandilli Oservatory and Earthquake Research Institute in Istanbul (KOERI-RETMC) at magnitude 4.1, The Seismological Survey of Serbia (SSS) at magnitude 4.1, the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.0, The Seismological Laboratory of the University of Athens (UOA) at magnitude 4.0, The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 3.9, and the citizen-seismograph network of RaspberryShake at magnitude 4.3.
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
