5.2 magnitude earthquake in northern Greece

A 5.2-magnitude earthquake struck northern Greece early today, the country's earthquake observatory said, with no reports of victims or major damage.
The tremor struck at 0016 GMT, with its epicentre 20 kilometres from the northern town of Arta and 249 kilometres northeast of the capital Athens, according to the observatory.
Earthquakes occur regularly in Greece.
A tremor on May 24 near the island of Lemnos caused injuries in neighbouring Turkey, while in January thousands of people were left homeless by a quake on the Ionian island of Cephalonia, in the west of the country.
