A moderate earthquake struck off the Greek island of Zakynthos on Tuesday evening, rattling buildings but causing no immediate reports of injuries or major damage, authorities said.
According to the revised assessment by Greece’s Geodynamic Institute, the 4.7-magnitude quake occurred at 7:53 p.m. local time, about 85 kilometers (53 miles) southwest of Agios Leon on Zakynthos. The quake had a shallow focal depth of 9.2 kilometers (5.7 miles), which made it widely felt across parts of the Ionian Islands.
The Euro-Mediterranean Seismological Centre (EMSC) measured the quake at magnitude 4.6, placing the epicenter about 52 kilometers (32 miles) southwest of Zakynthos, with a focal depth of 10 kilometers (6.2 miles).
Local authorities said there were no immediate reports of injuries or significant structural damage, but emergency services were placed on alert as a precaution.
Greece lies in one of Europe’s most seismically active regions, and Zakynthos, located along the Hellenic Arc, has experienced frequent earthquakes in recent years. Seismologists said aftershocks were possible but were not expected to pose a major threat.
Officials urged residents to remain cautious and follow standard safety guidance in case of additional tremors.
