A second report was later issued by Turkey’s Disaster and Emergency Management Authority (AFAD), which listed it as a magnitude 4.0 earthquake. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 3.8, the citizen-seismograph network of RaspberryShake at magnitude 3.9, The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 3.7, and The Seismological Laboratory of the University of Athens (UOA) at magnitude 3.8.
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 Vatos (pop. 11) located 10 km from the epicenter, Nea Anatoli (pop.
