ATHENS, Greece: An earthquake with a preliminary magnitude of 5.2 struck southern Greece on Friday, but did not cause any damage or injuries, the Athens Geodynamic Institute said.
The quake occurred at 9:10 a.m. beneath the seabed, with an epicenter about 170 miles south-southwest of Athens, the institute said.
The U.S. Geological Survey gave a preliminary magnitude of 4.9. Preliminary magnitudes often differ in the hours or even days after an earthquake.
A month ago, two strong quakes with magnitudes of 6.5 and 6.4 struck the same area and were felt as far away as Italy and Egypt. They did not cause any significant damage and nobody was hurt.
The Athens Geological Institute said Friday's earthquake was considered to be an aftershock.
