In 1999, two destructive earthquakes (M7.4 Kocaeli and M7.2 Duzce) occurred in the north west of Turkey and resulted in major stress-drops on the western segment of the North Anatolian Fault system where it continues under the Marmara Sea. These undersea fault segments were recently explored using bathymetric and reflection surveys. These recent findings helped to reshape the seismotectonic environment of the Marmara basin, which is a perplexing tectonic domain. Based on collected new information, seismic hazard of the Marmara region, particularly Istanbul Metropolitan Area and its vicinity, were re-examined using a probabilistic approach. Two seismic source and alternate recurrence models combined with various indigenous and "foreign'' attenuation relationships were adapted within a logic tree formulation to quantify and project the regional exposure on a set of hazard maps. The hazard maps show the peak horizontal ground acceleration and spectral acceleration at 1.0 s. These acceleration levels were computed for 2 and 10 % probabilities of transcendence in 50 years.

Neotectonics of the southeast Marmara region, NW Anatolia, Turkey
Gürer, Ömer Feyzi; Kaymakcı, Nuretdin; Çakır, Şerafeddin; Kaymakcı, Nuretdin (Elsevier BV, 2003-7)
The North Anatolian Fault Zone (NAFZ) bifurcates into three branches in the Marmara Region, which is a transition zone between the strike-slip tectonics manifested by the NAFZ and the N-S directed extensional regime of western Anatolia. The southern Marmara region is characterized by the middle and the southern branches while the northern branch controls the north Marmara region. The south Marmara region is characterized by approximately E-W trending rhomb-like horst and graben complexes bounded by strike s...
Seismic Protection of Museum Collections: Lessons Learned After the 1999 Earthquakes in Turkey
Ertürk, Nevra (Middle East Technical University, Faculty of Architecture, 2012-6-1)
Turkey has a long history of large earthquakes in three major fault zones that place two-thirds of the country. Following the two major earthquakes that struck the nortwestern part of Turkey in 1999, several attempts have been taken at hospitals, schools or administrative buildings. The two earthquakes prompted museum professionals and policymakers to consider measures to protect museum collections as well as buildings against earthquake. After the 1999 earthquakes, various projects, scientific researches, ...
Flood forecasting and analysis within the Ulus Basin, Turkey, using geographic information systems
Usul, Nurunnisa; Turan, Burak (Springer Science and Business Media LLC, 2006-10-01)
Floods have been the most severe natural disasters in the West Black Sea Region of Turkey for many years; therefore Ulus Basin is selected as a study area for a thorough hydrologic flood analysis. The lack of embankments around the Ulus River and careless changes to the riverbed made by villagers, resulted in major flood events in the basin, causing significant damage in the area. In this study, the hydrodynamic characteristics of the basin and the riverbed are determined by calibrating the hydraulic module...
Numerical modelling of the 1766 (May) earthquake tsunami scenario along the northern coasts of Marmara Sea, Turkey
Vardar, Hande; Alpar, Şaban Bedri; Yalçıner, Ahmet Cevdet (null; 2018-04-09)
Following the recent 1999-earthquake disaster and its associated tsunami that occurred in the Izmit Gulf, eastern part of the Marmara Sea; much research has been carried out to determine the tsunami potential, as well as their possible effects along the adjacent coast. Based on the available archival data, many tsunamis (e.g. 989, 1343, 1509, 1766, 1894 and 1912) have affected the low-lying coasts, bays, estuaries, straits and possibly coastal lagoons along the northern coast of the Marmara Sea. In the pres...
Complete Tsunami Hazard Assessment, Vulnerability and Risk Analysis for the Marmara Coast of Istanbul Metropolitan Area
Yalçıner, Ahmet Cevdet; Süzen, Mehmet Lütfi; Tüfekçi Enginar, Duygu; Yalçıner, Bora; Kolat, Çağıl; Baş, Mahmut; Kılıç, Osman; Menteşe, Emin Yahya; Tarih, Ahmet; Zaytsev, Andrey; Pelinovski, Efim (null; 2019-04-07)
According to east to west propagation of major earthquakes along the North Anatolian Fault (NAF) since seventeenth century, a large magnitude (at least M=7.2) earthquake is expected to occur in the Sea of Marmara where the megacity of Istanbul located at the northern coast of the sea. There are numerous possibilities about the tsunami generation in the Sea of Marmara. In order to assess tsunami risk properly; collection and processing of high-resolution data and tsunami numerical modeling are necessary. In ...
