Paleoseismology of the Ganos segment; the western extend of the North Anatolian Fault (Turkey)

The Ganos fault that ruptured on 9 August 1912 (Mw: 7.4) is the westernmost inland segment of North Anatolian (NAF). Here, bounded at its two tips with offshore faults segments, in Sea Marmara to east and Gulf Saros west Aegean Trough. Therefore, paleoseismology 45-km-long importance seismic hazard analysis related active particular for gap Region. Earlier studies have established an earthquake chronology western eastern fault. we extend paleoseismic toward central segment. Three trenches Yörgüç revealed evidence faulting events, possibly post-1669 CE ±30 years, which can be correlated 1659 or 1766, historical earthquakes. At Yeniköy, determined offset 46 ± 1 m 47 a stream channel ridge-crest, respectively. In events last 1000 years seven 3500 years. trench T5, base displaced provides calibrated date 829?591 BCE.
