An earthquake of magnitude 4.0 occurred only 9 minutes ago 66 km east of Volos, Greece, the European-Mediterranean Seismological Centre (EMSC) reported.The quake hit at a very shallow depth of 5. km beneath the epicenter near Volos, Magnesia, Thessaly, Greece, late at night on Tuesday, July 28th, 2026, at 10:17 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.A second report was later issued by the National Observatory of Athens (NOA), which listed it as a magnitude 4.1 earthquake. Other agencies reporting the same quake include The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 4.0, The Seismological Laboratory of the University of Athens (UOA) at magnitude 4.1, and the citizen-seismograph network of RaspberryShake at magnitude 4.1.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 Glossa (pop. 990) located 16 km from the epicenter, Skopelos (pop. 2,900) 20 km away, Patitirion (pop. 1,600) 22 km away, Skiathos (pop. 5,200) 24 km away, and Argalasti (pop. 1,300) 43 km away.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Agria (pop. 5,500) located 60 km from the epicenter, Istiaia (pop. 4,300) 62 km away, Volos (pop. 86,000) 66 km away, and Nea Ionia (pop. 32,700) 68 km away.Earthquake data: Date & time: Jul 28, 2026 10:17 pm (Athens time) local time (28 Jul 2026 19:17 GMT)Magnitude: 4.0Depth: 5.00 kmEpicenter latitude / longitude: 39.3°N / 23.71°E (Greece)Primary data source: EMSC
