(Reuters) - A 4.5-magnitude earthquake struck southern Greece on Friday in the Peloponnese region, the U.S. Geological Survey said.
The quake was located 104 miles southwest of Kalamata at a depth of 21.5 miles, the agency said.
Greece is prone to earthquakes. Most cause no serious damage, but a 5.9 magnitude quake in 1999 killed 143 people.
