A strong 5.3-magnitude earthquake struck off the coast of the southwestern Peloponnese on Sunday evening, rattling the Messinia region but causing no immediate structural damage or casualties.
The Athens Geodynamic Institute issued an updated seismic bulletin stating the tremor occurred at 9:17 p.m. local time. Seismologists located the epicenter in the Ionian Sea, roughly 18 kilometers (11 miles) south-southwest of the historic coastal town of Methoni.
The earthquake originated at a shallow focal depth of 9 kilometers (5.6 miles).
The shaking was felt heavily across Messinia, prompting startled residents to briefly gather in town squares in Pylos and the regional capital of Kalamata.
Local civil protection teams immediately launched localized search patrols along vulnerable perimeter infrastructure, but regional directors confirmed that all emergency service communications reported zero calls for structural damage, collapsed masonry, or secondary utility line disruptions.
