A major thrust-fault earthquake of M-w = 7.0 occurred on 23 October 2011 at 10:41:21 UTC in the eastern Anatolian region of Turkey, severely affecting the nearby towns of Van and Ercis. In this study, a few strong-motion records from the epicentral area are analyzed in order to investigate the characteristics of the ground motions. Also reported are the post-earthquake field observations for various types of structures, such as buildings, bridges, historical structures, tunnels, and dams within the vicinity of the fault plane. The spatial distribution of damage indicates a noticeable hanging-wall effect. The special-type structures are observed to experience far less damage, as opposed to the building structures in the region pointing to the need for strict compliance to seismic building code and the corresponding construction requirements.

Discussion of "Subsurface characterization at ground failure sites in Adapazari, Turkey" by Jonathan D. Bray, Rodolfo B. Sancio, Turan Durgunoglu, Akin Onalp, T. Leslie Youd, Jonathan P. Stewart, Raymond B. Seed, Onder K. Cetin, Ertan Bol, M. B. Baturay, C. Christensen, and T Karadayilar - July 2004, vol. 130, no. 7, pp. 673-685. Bakır, Bahadır Sadık (American Society of Civil Engineers (ASCE), 2006-04-01) Ground failure in Adapazari, Turkey during the 1999 Kocaeli earthquake was severe. Hundreds of structures settled, slid, tilted, and collapsed due in part to liquefaction and ground softening. Ground failure was more severe adjacent to and under buildings. The soils that led to severe building damage were generally low plasticity silts. In this paper, the results of a comprehensive investigation of the soils of Adapazari, which included cone penetration test ~CPT! profiles followed by borings with standard ...
A comparative study on the actual and estimated seismic response of Kiralkizi Dam in Turkey Çetin, Kemal Önder; Batmaz, S; Karabiber, S (Informa UK Limited, 2005-07-01) Kiralkizi Dam, a 120 in high earthfill dam located in Diyarbakir city, Turkey, was shaken by a moment magnitude, M-w = 4.6 earthquake at an epicentral distance of 8 km, on December 24, 2000, at 13:31 local time. The seismic response of the dam was assessed by using spectral ratios between (i) available crest and foundation records (C/F), (ii) horizontal and vertical components of the recorded motions (H/V), (iii) by performing 2 dimensional finite difference-based seismic response analyses (Flac-2D), and (i...
Probabilistic benefit-cost analysis for earthquake damage mitigation: Evaluating measures for apartment houses in Turkey Smyth, AW; Altay, G; Deodatis, G; Erdik, M; Franco, G; Gulkan, P; Kunreuther, H; Lus, H; Mete, E; Seeber, N; Yuzugullu, O (SAGE Publications, 2004-02-01) In the wake of the 1999 earthquake destruction in Turkey, the urgent need has arisen to evaluate the benefits of loss mitigation measures that could be undertaken to strengthen the existing housing stock. In this study, a benefit-cost analysis methodology is introduced for the comparative evaluation of several seismic retrofitting measures applied to a representative apartment building located in Istanbul. The analysis is performed probabilistically through the development of fragility curves of the structu...
The 2014 seismic hazard model of the Middle East: overview and results Şeşetyan, Karin; et. al. (Springer Science and Business Media LLC, 2018-08-01) The Earthquake Model of Middle East (EMME) Project aimed to develop regional scale seismic hazard and risk models uniformly throughout a region extending from the Eastern Mediterranean in the west to the Himalayas in the east and from the Gulf of Oman in the south to the Greater Caucasus in the North; a region which has been continuously devastated by large earthquakes throughout the history. The 2014 Seismic Hazard Model of Middle East (EMME-SHM14) was developed with the contribution of several institution...
Displacement-based fragility functions for low- and mid-rise ordinary concrete buildings Akkar, S; Sucuoğlu, Haluk; Yakut, Ahmet (SAGE Publications, 2005-11-01) Fragility functions are determined for low- and mid-rise ordinary concrete buildings, which constitute the most vulnerable construction type in Turkey as well as several other countries prone to earthquakes. A hybrid approach is employed where building capacities are obtained from field data and their dynamic responses are calculated by response history analyses. Field data consists of 32 sample buildings representing the general characteristics of two-to five-story substandard reinforced concrete buildings...
