"One person, who jumped down from a balcony in Balikesir's Edremit district, is in critical condition," the Prime Ministry Disaster and Emergency Management Agency (AFAD) said in a statement.
Some 20 aftershocks were recorded after the earthquake, Xinhua reported.
The quake was felt in a large area in western and north-western Turkey, including Marmara region and Istanbul, the largest city of the country.
