(AUTH) at magnitude 3.7, The Seismological Laboratory of the University of Athens (UOA) at magnitude 4.0, and the citizen-seismograph network of RaspberryShake at magnitude 3.9.
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 Kalotaritissa (pop. 20) located 11 km from the epicenter.
