The aim of this study is to determine the tsunami potential of the southern Turkish coast through hypothetical earthquake scenarios developed for several critical coastal sites in the region. A well-known tsunami numerical model (MOST) is utilized to calculate the run-up and inundation of the subsequent tsunami waves. The coastal regions selected to realize the aim of the study are Akkuyu and Yesilovacik from Mersin and Yumurtalik from Adana, which are chosen for their industrial and environmental importance. Time series of wave amplitudes at these three sites as well as contour plots presenting maximum wave amplitudes within the computational domain are generated for different earthquake moment magnitudes. Results obtained from the numerical model suggest that while earthquakes having magnitude smaller than 7.5 generate weak oscillations, earthquakes with magnitude greater than 7.5 result in significant waves reaching maximum wave height of a few meters at the selected coastal regions. Given the number and the magnitude scale of tsunamigenic earthquakes occurred in the region in the past, the modeling effort here indicates that hazard induced by tectonic tsunamis should seriously be taken into account by both the central and the local government authorities, who are responsible for pre- and post-disaster action planning. This issue is critical for minimizing the damage of a possible tsunami event. The proposed study is hoped to be used as a basis for future tsunami risk maps to be developed for the region.

Measurement and evaluation of the hydrodynamics and secondary currents in and near a strait connecting large water bodies - A field study
Gueler, Isikhan; Yueksel, Yalcin; Yalçıner, Ahmet Cevdet; Cevik, Esin; Ingerslev, Christian (Elsevier BV, 2006-09-01)
The straits connect two large water bodies show highly strong and stratified currents related to meteorological, morphological and hydrodynamic conditions. In some cases, spatial and temporal changes of the stratified currents and their thickness, direction and magnitude are so complex. This complexity directly affects the circulation pattern in the region, water exchange between both ends of the straits and migration of fish species. In order to understand general characteristics of this kind of straits an...
Possible worst-case tsunami scenarios around the Marmara Sea from combined earthquake and landslide sources
Latcharote, Panon; Suppasri, Anawat; Imamura, Fumihiko; Aytore, Betul; Yalçıner, Ahmet Cevdet (2016-12-01)
This study evaluates tsunami hazards in the Marmara Sea from possible worst-case tsunami scenarios that are from submarine earthquakes and landslides. In terms of fault-generated tsunamis, seismic ruptures can propagate along the North Anatolian Fault (NAF), which has produced historical tsunamis in the Marmara Sea. Based on the past studies, which consider fault-generated tsunamis and landslide-generated tsunamis individually, future scenarios are expected to generate tsunamis, and submarine landslides cou...
Seismic response of a rubble mound breakwater in Turkey
Yuksel, Y; Çetin, Kemal Önder; Ozguven, O; Isik, NS; Cevik, E; Sumer, BM (Thomas Telford Ltd., 2004-12-01)
This paper presents analyses of seismically induced deformations at Eregli Fishery Port breakwater during the 1999 Kocaeli (Izmit), Turkey earthquake. The paper discusses: (a) observed ground deformations and displacements after the earthquake; (b) the results of field investigations by means of borings including standard penetration tests; (c) analyses of observed deformation mechanisms by a suite of methods; and (d) the possible contribution of soil liquefaction rupture on the observed deformations.
Flow regimes and dynamic equilibrium of morphological changes at Köyceǧiz Lake inlet, Turkey
Özhan , Erdal (Elsevier BV, 1988-6)
Köyceǧiz Lake discharges into the southern Aegean Sea through a waterway of 14 km length. There exist variations in the local sand transport around the inlet during the year so that the cross-sections at the channel and the neighbouring sea bed topography show seasonal change exhibiting a dynamic equilibrium behavior. Field measurements were carried out at the inlet for about a year with the purpose of understanding the nature of water motions and the resulting sedimentation patterns. The observed dynamic e...
Understanding tsunamis, potential source regions and tsunami-prone mechanisms in the Eastern Mediterranean
Yolsal, S.; Taymaz, Tuncay; Yalçıner, Ahmet Cevdet (Geological Society of London, 2007-01-01)
Historical tsunamis and tsunami propagation are synthesized in the Eastern Mediterranean Sea region, with particular attention to the Hellenic and the Cyprus arcs and the Levantine basin, to obtain a better picture of the tsunamigenic zones. Historical data of tsunami manifestation in the region are analysed, and compared with current seismic activity and plate interactions. Numerical simulations of potential and historical tsunamis reported in the Cyprus and Hellenic arcs are performed as case studies in t...
