An earthquake of magnitude 5.2 occurred only 5 minutes ago 41 km southeast of Tekirdag, Turkey, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10. km beneath the epicenter near Tekirdag, Turkey, early afternoon on Thursday, October 2nd, 2025, at 2:55 pm local time. 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.
Our monitoring service identified a second report from the National Observatory of Athens (NOA) which listed the quake at magnitude 4.8. Other agencies reporting the same quake include The Seismological Survey of Serbia (SSS) at magnitude 4.9, the citizen-seismograph network of RaspberryShake at magnitude 5.2, and The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 4.6.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
