An earthquake of magnitude 5.0 occurred only 4 minutes ago 78 km southwest of Kavala, Greece, the European-Mediterranean Seismological Centre (EMSC) reported.
The quake hit at a very shallow depth of 5. km beneath the epicenter near Kavala, East Macedonia and Thrace, Greece, early morning on Monday, September 22nd, 2025, at 4:20 am 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 citizen-seismograph network of RaspberryShake which listed the quake at magnitude 5.2. Other agencies reporting the same quake include The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 4.7, the German Research Centre for Geosciences (GFZ) at magnitude 5.2, and The Seismological Laboratory of the University of Athens (UOA) at magnitude 4.8.
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.
In Nea Roda (pop. 1,200) located 23 km from the epicenter, Sarti (pop. 1,200) 24 km away, Ierissos (pop. 3,300) 27 km away, Sykia (pop. 1,900) 31 km away, and Neos

Background:
Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America’s 2nd-highest volcano. The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater. The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano.
At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano. The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone. Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano. Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian
