A very shallow magnitude 3.1 earthquake was reported in the morning near Thessaloniki, Central Macedonia, Greece.
According to the National Observatory of Athens (NOA), the quake hit on Sunday, November 2nd, 2025, at 9:28 am local time at a very shallow depth of 5. km. Shallow earthquakes are felt more strongly than deeper ones as 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 data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from The Seismological Survey of Serbia (SSS) which listed the quake at magnitude 3.4. Other agencies reporting the same quake include The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 3.3, The Seismological Laboratory of the University of Athens (UOA) at magnitude 3.2, the European-Mediterranean Seismological Centre (EMSC) at magnitude 3.2, and the citizen-seismograph network of RaspberryShake at magnitude 3.1.
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 Kalochori (pop. 4,700) located 7 km from the epicenter, and Kalamaria (pop. 91,500) 8 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Thessaloniki (pop. 317,800) located 10 km from the epicenter, Neapoli (pop. 27,100) 11 km away, Pylaia (pop. 34,600) 11 km away, Sykies (pop. 45,000) 11 km away, Evosmos (pop. 74,700) 11 km away, Stavroupoli (pop. 46,000) 12 km away, and Polichni (pop. 56,700) 13 km away.
