Resilience of coastal utilities after earthquakes and tsunamis has major importance for efficient and proper rescue and recovery operations soon after the disasters. Vulnerability assessment of coastal areas under extreme events has major importance for preparedness and development of mitigation strategies. The Sea of Marmara has experienced numerous earthquakes as well as associated tsunamis. There are variety of coastal facilities such as ports, small craft harbors, and terminals for maritime transportation, water front roads and business centers mainly at North Coast of Marmara Sea in megacity Istanbul. A detailed vulnerability analysis for Yenikapi region and a detailed resilience analysis for Haydarpasa port in Istanbul have been studied in previously by Cankaya et al., (2015) and Aytore et al., (2015) in SATREPS project. In this study, the methodology of vulnerability analysis under tsunami attack given in Cankaya et al., (2015) is modified and applied to Bakirkoy district of Istanbul. Bakirkoy district is located at western part of Istanbul and faces to the North Coast of Marmara Sea from 28.77oE to 28.89oE. High resolution spatial dataset of Istanbul Metropolitan Municipality (IMM) is used and analyzed. The bathymetry and topography database and the spatial dataset containing all buildings/structures/infrastructures in the district are collated and utilized for tsunami numerical modeling and following vulnerability analysis. The tsunami parameters from deterministically defined worst case scenarios are computed from the simulations using tsunami numerical model NAMI DANCE. The vulnerability assessment parameters in the district according to vulnerability and resilience are defined; and scored by implementation of a GIS based TVA with appropriate MCDA methods. The risk level is computed using tsunami intensity (level of flow depth from simulations) and TVA results at every location in Bakirkoy district. The preliminary results are presented and discussed.

Probabilistic seismic hazard assessment for earthquake induced landslides
Balal, Onur; Gülerce, Zeynep; Department of Civil Engineering (2013)
Earthquake-induced slope instability is one of the major sources of earthquake hazards in near fault regions. Simplified tools, such as Newmark’s Sliding Block (NSB) Analysis are widely used to represent the stability of a slope under earthquake shaking. The outcome of this analogy is the slope displacement where larger displacement values indicate higher seismic slope instability risk. Recent studies in the literature propose empirical models between the slope displacement and single or multiple ground mot...
An assessment of the 3 February 2002 Cay (Turkey) earthquake (Mw=6.6): Modeling of ground motions and felt intensity distribution
Can, Gizem; Askan Gündoğan, Ayşegül (2021-11-01)
Estimation of earthquake ground motions is important for several purposes including seismic design, analysis, risk mitigation and disaster management. For regions with insufficient data, simulations become critical, particularly for earthquake engineering applications requiring full ground motion data. In this study, stochastic finite-fault simulation of the 3 February 2002 Cay event is presented at three available stations within epicentral distances less than 200 km. The simulations are initially validate...
The evaluation of public awareness and community preparedness parameter in GIS-based spatial tsunami human vulnerability assessment (MeTHuVA)
Tüfekçi Enginar, Duygu; Süzen, Mehmet Lütfi; Yalçıner, Ahmet Cevdet (Springer Science and Business Media LLC, 2020-11-01)
Catastrophic tsunami events in the past decades reveal the need to improve disaster risk reduction management systems. Although the actions born with this need began in the countries affected by the recent major events, mainly in Indonesia, after the 2004 Indian Ocean tsunami and in Japan, after the 2011 Tohoku tsunami, it started to spread to other tsunami-prone coastal areas. The development of risk reduction strategies begins with determining the possible worst-case scenarios for the region and identifyi...
An Assessment of disaster risk management in a world heritage site in Turkey: the case of Bergama
Aygün Gürsoy, Aslı; Bilgin Altınöz, Ayşe Güliz; Conservation of Cultural Heritage in Department of Architecture (2019)
The number of disasters in the world is increasing each year due to various natural, human-induced, and climate change-induced hazards such as earthquakes, floods, fires, and many others. Hence, cultural heritage sites, which are unrenewable resources, are under destructive effects of such disasters. In order to safeguard heritage places that are threatened, international studies have been accelerated in recent years. A manual entitled 'Managing Disaster Risks for World Heritage' was prepared by UNESCO, ICC...
A GIS-based software for lifeline reliability analysis under seismic hazard
Kestel, Sevtap Ayşe; ODUNCUOĞLU, Lütfi (2012-05-01)
Lifelines are vital networks, and it is important that those networks are still functional after major natural disasters such as earthquakes. Assessing reliability of lifelines requires spatial analysis of lifelines with respect to a given earthquake hazard map. In this paper, a GIS-based software for the spatial assessment of lifeline reliability which is developed by using GeoTools environment is presented. The developed GIS-based software imports seismic hazard and lifeline network layers and then create...
