1912 Mürefte earthquake

The 1912 Mürefte earthquake occurred at 03:29 local time on 9 August. It had an estimated [Seismic Seismic magnitude scales|magnitude scales|magnitude] of 7.4 and a maximum intensity of X on the Modified Mercalli intensity scale, causing from 216 to 3,000 casualties.

Earthquake

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

Tsunami

A tsunami was associated with undersea landslides that triggered waves up to high. Evidence of landslides from the 1912 event was found at the southern edge of the Tekirdağ Basin. In the Bosporus Strait, the tsunami destroyed a yacht located at Paşabahçe.
