Athens, Greece - A magnitude 5.2 earthquake struck the western island of Zakynthos early Sunday, causing no injuries or damage, authorities said.
The Athens Geodynamic Institute said Saturday's undersea quake occurred at 8:42 a.m. (0642 GMT), about 250 kilometers (150 miles) west of Athens. The epicenter was south of Zakynthos, the Institute said.
Locals were somewhat concerned by the duration of the earthquake, authorities said, but there was no widespread panic as the area produces frequent strong earthquakes.
