An earthquake with a preliminary magnitude of 5.1 rattled parts of Greece on Monday, with the tremor felt in Athens, witnesses said.
The Institute of Geodynamics at the National Observatory of Athens said the tremor occurred 53 km south-east of the island of Hydra, and at a depth of almost 90 kms - deep enough to reduce the chances of damage at ground level. It was felt in parts of Athens 120 kms away as well as areas of the Peloponnese.
The fire brigade said there were no immediate reports of any damage.
