A magnitude 5.3 earthquake struck in the sea south of Methoni, Messinia, shortly after 9 p.m. local time on Sunday, shaking buildings across the Peloponnese and triggering a civil protection mobilization. No damage or injuries have been reported.
The earthquake
A shallow earthquake of magnitude 5.3 on the Richter scale struck in the marine area south of Methoni at 9:17 p.m. local time (18:17 UTC) on Sunday, 14 June 2026. The Geodynamic Institute located the epicenter 15 to 18 kilometres south-southwest of the town, at a focal depth of just 9 kilometres. The tremor was strongly felt in nearby towns including Kalamata, Pylos, and Methoni itself, and across much of the Peloponnese, with residents reporting a shaking duration of about 10 seconds in Megalopoli. Light shaking was also felt in the Attica region, including the capital Athens.
Seismological context
Seismologist Gerasimos Papadopoulos, posting on social media shortly after the event, described the quake as a strong shallow earthquake. He noted that it is too early to determine whether it was the main shock or a foreshock.
It is too early to assess whether it was the main quake or not. The region has high seismic potential. The most recent large earthquake there occurred on 14 February 2008 with magnitude 6.6.
Papadopoulos added that the area south of Pylos has a history of significant seismic activity.
Preparedness and response
In the immediate aftermath, the Chief of the Hellenic Fire Service, Vice General Theodoros Vagias, ordered fire services across the Peloponnese region and the 1st Special Disaster Unit (EMAK) to heightened readiness. Civil protection forces were dispersed throughout the wider area for patrols, while police and coast guard units also mobilized. The Fire Service operations centre stated that no calls for trapped persons had been received and no building damage had been reported as of Sunday evening. Patrols continue across Messinia.
