ATHENS, Sept 2, 2010 (AFP) - An undersea earthquake measuring 4.3 points on the Richter scale rattled Athens early on Thursday, the Athens geodynamic institute said.

The quake in the Corinthian Gulf struck at 06:53 am (0353 GMT), with an epicentre 60 kilometres (37 miles) west of the capital, near to the town of Lefktra, it said. No damage was reported.

Greece accounts for half the earthquakes on the European continent.
