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 present study, probabilistic earthquake simulations of the May 22, 1766 earthquake and amplification of related tsunami waves along the coasts will be presented using a numerical model called NAMIDANCE. It is a tested tsunami simulation and visualization tool, and used to create tsunami inundation maps. The source parameters were chosen from the recent tsunami catalogue given by Altinok et al (2011) as derived from available marine geophysical data. The temporal fluctuations of the near-shore water surface were plotted at several coastal locations, depending on the available GEBCO 30 arc-second grid data enhanced with satellite images. The modelling results show that the waves of the 1766 (May) tsunami reached the selected gauge points along the northern coasts of the Marmara Sea.

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 ...
Evaluation of tsunami scenarios for western Peloponnese, Greece Yalçıner, Ahmet Cevdet; Dilmen, D. I.; Aytore, B.; Ayca, A.; Insel, I.; Zaytsev, A. (2014-06-01) Tsunami hazard assessment of the eastern part of the Mediterranean Sea is the current interest of the countries having, a coastline in this region. Considering today's increasing population on the coasts and historical tsunamis, it is essential to estimate the probable tsunami risk, which might occur, to be able to mitigate the risk before the actual tsunami event happens. For this purpose, European Union funded project., SEAHELLARC is formed to develop a methodology and tools for seismic and tsunami safety...
Reconnaissance of 2020 M 7.0 Samos Island (Aegean Sea) earthquake Çetin, Kemal Önder; Sextos, Anastasios; Stewart, Jonathan P. (2021-08-01) The Samos Island (Aegean Sea) Earthquake occurred on 30 October 2020. It produced a tsunami that impacted coastal communities, ground shaking that was locally amplified in some areas and that led to collapse of structures with 118 fatalities in both Greece and Turkey, and wide-ranging geotechnical effects including rockfalls, landsliding, and liquefaction. As a result of the global COVID-19 pandemic, the reconnaissance of this event did not involve the deployment of international teams, as would be typical ...
Undrained cyclic shear and deformation behavior of silt-clay mixtures of Adapazan, Turkey Yilmaz, MT; Pekcan, Onur; Bakir, BS (2004-09-01) The city of Adapazari, which is mostly located on a deep alluvial basin in the near field of the ruptured fault, experienced substantial damage during the 17 August 1999 Kocaeli (Izmit), Turkey earthquake (M-w 7.4). Besides over 2800 collapsed and heavily damaged buildings in the city, numerous cases of displacements of various forms and levels occurred at the building foundations. The undrained shear and deformation behavior of silt-clay mixtures encountered at the sites with significant foundation displac...
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...
