Earthquake

The earthquake was associated with faulting along the Ganos Fault, a segment of the

North Anatolian Fault The North Anatolian Fault (NAF; ) is an active right-lateral strike-slip fault in northern Anatolia, and is the transform boundary between the Eurasian plate and the Anatolian sub-plate. The fault extends westward from a junction with the Ea ...

. Geologic trenching revealed coseismic offsets occurred along the entire onshort section of the Ganos Fault. These right-lateral displacements reached up to . For its surface-wave magnitude ( 7.3–7.4), its corresponding rupture length would be approximately . This implied the offshore segments east and west of the onshore Ganos Fault also ruptured. In the

Marmara Sea The Sea of Marmara, also known as the Sea of Marmora or the Marmara Sea, is a small inland sea entirely within the borders of Turkey. It links the Black Sea and the Aegean Sea via the Bosporus and Dardanelles straits, separating Turkey's E ...

, young fault scarps and right-lateral offsets up to were found. West of the Ganos Fault is the Saros Fault that lies beneath a bay; estimates of the Saros Fault rupture are between and . Meanwhile, another of rupture may have extended eastwards into the Marmara Sea.
