A powerful quake of magnitude at least 6.4 struck off western Greece early on Friday, earthquake monitors said, causing slight damage but no casualties in a tremor felt as far away as Libya.
Greece’s Geodynamic Institute reported the magnitude as 6.4, and put the quake 50 km (31 miles) south of the island of Zakynthos. That compares with a figure of 6.8 assessed by both the U.S. Geological Survey (USGS) and the European-Mediterranean Seismological Centre (EMSC).
The tremor was felt in Athens, the Greek capital, and as far away as Albania, Italy, Libya and Malta.
The epicenter was in the Ionian Sea, about 130 km (81 miles) southwest of Patras in the Peloponnese, the USGS said.
It was felt particularly on Zakynthos, also known as Zante, which was rattled by a series of strong aftershocks, the highest at 5.6, and where power was briefly disrupted.
