On 23 October 2011, and then on 9 November 2011, two earthquakes struck the province of Van in eastern Turkey. One month after the first earthquake, between 25 November and 27 November 2011, a reconnaissance team from the Middle East Technical University, Disaster Management Implementation and Research Center (METU DMC) visited the region. The team focused on disaster management activities such as emergency relief, damage assessment, psychosocial support, and economic impacts. Field observations and personal interviews concluded that deficits in mitigation led to shortcomings in the response and rehabilitation operations in Van. Although search and rescue activities were evaluated as satisfactory, there were problems in the organization of support services, temporary accommodation, and delivery of basic needs. This paper presents a reconnaissance report outlining the observations of the interdisciplinary team in the field. It suggests some policies for improvement in the disaster management system in the future.

Effects of the eastern Marmara earthquake on marine structures and coastal areas
Yuksel, Y; Alpar, B; Yalçıner, Ahmet Cevdet; Cevik, E; Ozguven, O; Celikoglu, Y (Thomas Telford Ltd., 2003-06-01)
The eastern Marmara earthquake occurred on 17 August 1999 with an Mw = 7.4 and struck the Izmit Bay and eastern Marmara Sea region, north-west Turkey. The main fault is a single strike-slip fault approximately 140 km long, starting from Sapanca Lake in the east and ending in Izmit Bay in the west. Existing industrial plants and various types of marine structure along the coast of Izmit Bay near this large-magnitude earthquake area provided valuable opportunity to examine the behaviour of marine structures t...
Damage in Reinforced Concrete Buildings during the 2011 Van Turkey Earthquakes
Baran, Eray; GÜNEŞ, BURCU (American Society of Civil Engineers (ASCE), 2014-06-01)
Two major earthquakes with magnitudes Mw=7.2 (ML=6.7) and ML=5.6 occurred in eastern Turkey on October 23 and November 19, 2011. The maximum measured peak ground accelerations for the two ground motions were 0.18g and 0.25g, respectively. The earthquakes resulted in various levels of damage to RC moment-resisting frame buildings ranging from minor cracking in brick partition walls to total collapse. This paper summarizes the field observations of the Atilim University Reconnaissance Team carried out in the ...
An evaluation of the strong ground motion recorded during the May 1, 2003 Bingol Turkey, earthquake
Akkar, S; Boore, DM; Gulkan, P (Informa UK Limited, 2005-03-01)
An important record of ground motion from a M6.4 earthquake occurring on May 1, 2003, at epicentral and fault distances of about 12 and 9 km, respectively, was obtained at a station near the city of Bingol, Turkey. The maximum peak ground values of 0.55 g and 36 cm/s are among the largest ground-motion amplitudes recorded in Turkey. From simulations and comparisons with ground motions from other earthquakes of comparable magnitude, we conclude that the ground motion over a range of frequencies is unusually ...
Strengthening of reinforced concrete frames by custom shaped high strength concrete masonry blocks
Arslan, Güray; Polat, Mustafa Uğur; Department of Civil Engineering (2009)
Located on one of the highly active seismic fault systems in the world, the building stock in Turkey is mainly composed of reinforced concrete frames with 4-5 stories. Due to design and construction deficiencies resulting from the use of unqualified personnel and insufficient supervision, many of these buildings lack lateral stiffness, ductility and strength. For many structures, there is a need to alleviate these deficiencies by means of some rehabilitation techniques prior to earthquakes. One approach als...
The 23 October 2011 M(w)7.0 Van (Eastern Turkey) Earthquake: Interpretations of Recorded Strong Ground Motions and Post-Earthquake Conditions of Nearby Structures
Akansel, V.; Ameri, G.; Askan Gündoğan, Ayşegül; Caner, Alp; Erdil, B.; Kale, O.; Okuyucu, D. (SAGE Publications, 2014-05-01)
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...
