Earthquake rattles southern Greece

Seismologists say an earthquake with a preliminary magnitude of 5.7 rattled southern Greece and was widely felt in the capital, Athens. There were no immediate reports of injuries or damage.
The US Geological Survey put the preliminary magnitude at 5.7, with an epicenter 25 kilometers east of the island of Hydra and about 78 kilometers south of Athens.
The Web site of the Athens Geodynamic Institute put the magnitude at 5.6. Different seismology institutes often have varying magnitudes in the early hours after a quake.
The quake occurred at 0138 IST.
Greece lies in a very seismically active area. A series of strong earthquakes in January on the western island of Kefalonia damaged hundreds of homes and injured more than a dozen people.
