The Greek police reported an earthquake measuring 6.7 magnitude struck off the western Greek island of Lefkada on Tuesday.
However, there have been no reports of any damages or injuries so far.
Earlier, the U.S. Geological Survey reported a magnitude 6.7 quake had occurred 10 km below the Earth's surface. A second reading gave a magnitude of 6.8 and a depth of just 5 km.
