Many parts of Turkey are subject to earthquakes. The Bosphorus and the Dardanelles owe their existence to the fault lines running through Turkey, leading to the creation of the Black Sea. There is an earthquake fault line across the north of the country from west to east. Within the last century there were many earthquakes along this fault line, the sizes and locations of these earthquakes can be seen on the Fault lines & Earthquakes image. This image also includes a small scaled map that shows other fault lines in Turkey.
