Evaluation of coastal risk at selected sites against eastern mediterranean tsunamis

Mediterranean, the center of civilizations since antiquity, experienced numerous earthquakes and triggered tsunamis. Historical information and distribution of fault zones, volcanoes and other probable tsunamigenic sea bottom deformations show that, there are source areas which may be considered as responsible for tsunamis in Eastern Mediterranean, Aegean, Marmara and Black sea region. These events affected the coastal structures that led to the loss of the economic power and social life of civilizations since antiquity. One of the probable examples of the earthquake or tsunami effects on the Fethiye town may be the eruption of Thera (also referred to as the Thera eruption or Santorini eruption). Another example of the earthquake or tsunami effects on the historical structures may be the destruction of lighthouse of Patara (Lykian City) harbor at the South of Turkey. The numerical modeling is one of the efficient tools for understanding the tsunami behaviors in the past. In this study, the historical data of earthquakes and tsunamis are evaluated together with the instrumental data of seismicity in order to select the tsunami source for modeling efforts. In modeling application, the most effective tsunami source among the others in Eastern Mediterranean is selected and simulated in order to better understand its possible effects on Fethiye town and the Patara (Lykian City). In this study, the simulation results are presented and dicussed for these selected regions.


Assessment of inland tsunami parameters and their effects on morphology /
Pamuk, Aykut; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2014)
Recent tsunami events clearly showed the potential of massive destruction on buildings, infrastructure, coastal protection structures and also morphological changes by tsunami waves. This thesis covers investigation of tsunami motion at inundation zone considering different factors (smoothed ground without buildings, or with buildings), and related changes of inland tsunami parameters and their effects on morphology. For the applications, the simulations have been performed using different topographic condi...
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...
Complete Tsunami Hazard Assessment, Vulnerability and Risk Analysis for the Marmara Coast of Istanbul Metropolitan Area

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 ...
Numerical assessment of tsunami attack on a rubble mound breakwater using OpenFOAM (R)
GÜLER, HASAN GÖKHAN; Baykal, Cüneyt; Arikawa, Taro; Yalçıner, Ahmet Cevdet (2018-03-01)
A numerical assessment study of tsunami attack on the rubble mound breakwater of Haydarpasa Port, located at the southern entrance of the Istanbul Bosphorus Strait in the Sea of Marmara, Turkey, is carried out in this study using a Volume-Averaged Reynolds-Averaged Navier-Stokes solver, IHFOAM, developed in OpenFOAM (R) environment. The numerical model is calibrated with and validated against the data from solitary wave and tsunami overflow experiments representing tsunami attack. Furthermore, attack of a p...
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 ...
