A moderate earthquake with a preliminary magnitude of 5.1 shook southwest Turkey on Monday, a seismology center said. There were no immediate reports of damage or injuries.
The epicenter of the quake was near the town of Cameli, in Denizli province, the Istanbul-based Kandilli observatory said.
Earthquakes are frequent in Turkey, much of which lies atop the active North Anatolian fault.
Two devastating earthquakes killed about 18,000 people in northwestern Turkey in 1999. In 2003, an earthquake measuring 6.4 magnitude collapsed a school dormitory in Bingol, in southeast Turkey, killing 83 children.
