An earthquake of 5.1 magnitude hit western Turkey on Thursday, Anatolia news agency reported, with no immediate reports of casualties or injuries.
The quake struck the town of Hisarcik in Kutahya province, it said.
Turkey is crossed by several fault lines.
A powerful quake shook eastern Turkey on October 23 last year, killing more than 600 people. It was followed on November 12 by a 5.6 magnitude tremor that killed another 40 people in the same area.
In 1999, two strong quakes in heavily populated and industrialised parts of northwest Turkey left some 20 000 people dead. - Sapa-AFP
