1912 Mürefte earthquake
Earthquake struck the Sea of Marmara, Turkey on August 9, 1912
From Wikipedia, the free encyclopedia
The 1912 Mürefte earthquake occurred at 03:29 local time on 9 August. It had an estimated magnitude of 7.4 Mw and a maximum intensity of X (Extreme) on the Modified Mercalli intensity scale, causing from 216 to 3,000 casualties.[4][5]
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 45 km (28 mi) onshort section of the Ganos Fault. These right-lateral displacements reached up to 5.5 m (18 ft). For its surface-wave magnitude (Ms 7.3–7.4), its corresponding rupture length would be approximately 135 ± 25 km (84 ± 16 mi). 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 6 m (20 ft) were found. West of the Ganos Fault is the Saros Fault that lies beneath a bay; estimates of the Saros Fault rupture are between 20 km (12 mi) and 50 km (31 mi). Meanwhile, another 30–60 km (19–37 mi) of rupture may have extended eastwards into the Marmara Sea.[6]
