ATHENS, Greece -- Greek geological experts say an earthquake with a preliminary magnitude of 4.5 has hit the western island of Zakynthos, but no damage has been reported.
The Athens Institute of Geodynamics reported that the temblor struck at 1:49 p.m. (1149 GMT) Sunday. The epicenter was 16 kilometers (10 miles) east of Zakynthos and the depth was 23.2 kilometers (14.4 miles).
Greece lies in an earthquake-prone zone and tremors of this magnitude are frequent. Zakynthos was hit by a magnitude 6.4 earthquake last Oct. 26, followed by dozens of aftershocks of at least 4.0-magnitude.
