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 locations nearby the Lake Van and Karasu River floodplain. Numerous sand boils and lateral spreading cracks were observed at the left and right embankments of the Karasu River, which is one of the major streams in the region. In this study, field observations on liquefaction and lateral spreading features triggered by the M (w) 7.2 Van earthquake are initially presented. Then, the results of subsurface investigations including trial pits, drillings and geophysical surveys on specific large-scale sand boils are explained. Subsequently, liquefaction back-analysis is performed considering the gathered subsurface data. The analysis indicates that the liquefaction occurred in a shallow zone with approximately 4 m thickness in the investigated area. The Liquefaction Potential Index method reveals high liquefaction potential for the analyzed sand boil location. In addition, the effect of cap soil thickness on liquefaction is once more validated by this case.

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.
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...
Damage risk assessment of breakwaters under tsunami attack Ergin, Ayşen (Springer Science and Business Media LLC, 2006-10-01) 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...
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...
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...
