Turkey was struck by two major events on 17 August and 12 November 1999, named Izmit (M-w = 7.4) and Duzce (M-w = 7.2) earthquakes, respectively. Rubble mound breakwaters in Izmit Bay experienced little damage, as forecasted by the new risk assessment model in which tsunami occurrence risk was included in the damage estimations. In order to determine the occurrence probability of structural damage under design conditions, including the environmental loading parameters of tsunami and storm waves, tidal range and storm surge, the Conditional Expections Monte Carlo simulation was applied in the risk assessment model developed in this study for the Esenkoy Fishery Harbour, Turkey. A tsunami was not the key design parameter when compared to storm waves for the main breakwater of the harbour, however, in places with great seismic activity, the tsunami risk should be important depending on the occurrence probability and magnitude of the tsunami.

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...
Patterns in the Turkish reinsurance claim data, 1998-2002: An application of the extreme value theory Başbuğ Erkan, Berna Burçak (Springer Science and Business Media LLC, 2006-10-01) The devastating 1999 Marmara and Duzce earthquakes led to a significant increase in the earthquake studies in Turkey in geological, engineering and financial aspects. Extreme Value Theory (EVT) has a range of applications from stock market changes to natural disasters like floods and hurricanes. Here EVT is fitted to the ordinary and earthquake reinsurance claims of Turkey.
Landslide risk assessment and management by decision analytical procedure for Derekoy, Konya, Turkey Duzgun, S. B.; Ozdemir, A. (Springer Science and Business Media LLC, 2006-10-01) The Derekoy landslide threatening the town of Derekoy, Konya, Turkey is investigated in order to assess and manage the associated risk. Derekoy town, located 12 km west of Konya city center, which is the second largest city in central Anatolia, has been extending due to the demand for new settlement places in Konya for the last decade. As most of the town is situated on the slopes of Meram river valley, on which the slope movements are observed, the risk of landslide has been increasing due to these new set...
Evaluation of liquefaction in Karasu River floodplain after the October 23, 2011, Van (Turkey) earthquake Akin, Mutluhan; Özvan, Ali; Akin, Muge K.; Topal, Tamer (Springer Science and Business Media LLC, 2013-12-01) The eastern shore of Lake Van was shaken by a powerful earthquake (M (w) 7.2) on October 23, 2011. The epicenter of the earthquake was located at about 30 km north of the Van Province, which is one of the main cities in the Eastern Anatolia. The Van Province and particularly its largest district Ercis were adversely affected by the earthquake, and unfortunately, a total of 600 people lost their lives. Besides severe constructional damages and building collapses, ground deformations were widespread at many l...
Real-time experimental forecast of the Peruvian tsunami of August 2007 for US coastlines Wei, Yong; Bernard, Eddie N.; Tang, Liujuan; Weiss, Robert; Titov, Vasily V.; Moore, Christopher; Spillane, Michael; Hopkins, Mike; Kanoğlu, Utku (American Geophysical Union (AGU), 2008-02-27) At 23: 41 UTC on 15 August 2007, an offshore earthquake of magnitude 8.0 severely damaged central Peru and generated a tsunami. Severe shaking by the earthquake collapsed buildings throughout the region and caused 514 fatalities. The tsunami resulted in three casualties and a representative maximum runup height of similar to 7 m in the near field. The first real-time tsunami data available came from a deep-ocean tsunami detection buoy within 1 hour of tsunami generation. These tsunami data were used to prod...
