ATHENS, Greece, June 7, 2026 – A powerful earthquake swarm rattled central Greece on Sunday afternoon, striking the northern Gulf of Evia and sending tremors across a wide area, including the Athens metropolitan region.
The seismic sequence unfolded within just four minutes near the town of Prokopi in northern Evia, producing three significant earthquakes and a series of aftershocks that prompted a large-scale emergency response.
According to revised data from the Greek Geodynamic Institute, the sequence began at 12:58 local time with a magnitude 4.8 earthquake located approximately 6 km (3.7 miles) southwest of Prokopi at a depth of 14.1 km (8.8 miles). This was followed at 13:00 by a magnitude 4.3 earthquake located 8 km (5 miles) west-northwest of Prokopi at a depth of 15.6 km (9.7 miles).

The strongest shock occurred at 13:02, when a magnitude 5.2 earthquake struck 5 km (3.1 miles) southwest of Prokopi at a depth of 13.1 km (8.1 miles). More than eight additional aftershocks, ranging from M2.7 to M4.3, followed in the minutes afterward, indicating an active and evolving seismic sequence.
Residents in Evia reported strong shaking lasting approximately 20 seconds, while tremors were also widely felt across Attica and several districts of Athens. Despite the widespread perception of the earthquakes, no injuries have been reported.
The earthquake sequence triggered an immediate response from Greek authorities.

By order of Fire Service Chief Lieutenant General Theodoros Vagias, firefighting units in both Evia and Attica were placed on heightened alert, along with specialized urban search-and-rescue teams from the 1st and 7th EMAK units.
More than 20 fire service vehicles were deployed across the affected region to conduct inspections of communities and road networks in cooperation with the Greek Police, while a rescue team from the 7th EMAK was dispatched to the area as a precautionary measure.
Authorities confirmed that, as of Sunday evening, the Fire Service Operations Center had received no reports of trapped individuals or rescue operations.
The Ministry of Climate Crisis and Civil Protection also placed disaster recovery and state assistance services on standby while maintaining constant communication with local authorities. Deputy Minister Evangelos Tournas traveled to the affected area alongside senior civil protection officials to assess conditions firsthand.
Preliminary inspections revealed limited but noticeable damage in parts of northern Evia.
Officials reported a partial wall collapse at a residential property, cracks in several homes, shops, and other buildings, as well as small landslides affecting sections of the local road network. According to local authorities, initial assessments suggest that five to six buildings may have sustained significant structural damage, although detailed inspections remain ongoing.
The mayor of Mantoudi, Limni, and Agia Anna announced that schools in Prokopi, including primary schools and the local middle school, will remain closed as a precaution while engineers assess buildings.
Despite the damage, authorities emphasized that no serious structural failures have been identified and no injuries have been recorded.
Seismologists Urge Caution
Greek seismologists have stressed that it remains too early to determine whether the magnitude 5.2 event was the main shock.
“This area is known for producing earthquakes of this type,” said Efthymios Lekkas, President of Greece’s Earthquake Planning and Protection Organization.
Meanwhile, Costas Papazachos, Professor of Seismology at the Aristotle University of Thessaloniki, stated that “the sequence is fully evolving,” highlighting the importance of monitoring activity during the coming days.
Experts are paying particular attention to the next 24 to 48 hours, a critical period that may reveal whether additional significant earthquakes could follow.
One of Greece’s Most Active Seismic Regions
The northern Gulf of Evia is among the most earthquake-prone regions in Greece, situated within the complex tectonic environment created by the interaction of the African and Eurasian plates.
Sunday’s earthquake swarm serves as another reminder of the country’s persistent seismic hazard. While the earthquakes caused localized damage, landslides, and considerable concern among residents, the absence of injuries and major structural failures has so far prevented a more serious emergency.
Authorities continue to monitor the situation closely as aftershocks persist and damage assessments continue across northern Evia.
