North Anatolian Fault

The North Anatolian Fault (NAF) (Template:Lang-tr) is an active right-lateral strike-slip fault in northern Anatolia which runs along the transform boundary between the Eurasian Plate and the Anatolian Plate. The fault extends westward from a junction with the East Anatolian Fault at the Karliova Triple Junction in eastern Turkey, across northern Turkey and into the Aegean Sea for a length of 1500 kilometers.^[1] It runs about 20 km south of Istanbul. The North Anatolian Fault is similar in many ways to the San Andreas Fault in California. Both are continental transforms with similar lengths and slip rates. The Sea of Marmara near Istanbul is an extensional basin similar to the Salton Trough in California, where a releasing bend in the strike-slip system creates a pull-apart basin.

Significant earthquakes

Since the disastrous 1939 Erzincan earthquake, there have been seven earthquakes measuring over 7.0 in magnitude,^[2] each happening at a point progressively further west.^[3] Seismologists studying this pattern believe that each earthquake may trigger the next.^[4] By analyzing the stresses along the fault caused by each large earthquake, earthquake earthquake earthquake earthquake earthquake
