The study is mainly focused on the dynamic soil characterization and determination of site effects for the PlioQuaternary and especially alluvial soils of the Çubuk district and its close vicinity in Ankara. It was observed that the shear wave velocity values for the uppermost 30 meter of the soil profile is not adequate to classify the sites properly and these values could not be correlated with the H/V results obtained from the microtremor records due to the great thicknesses of the soft sediments. The high fundamental periods and the low amplification ratios of the fault controlled region show that a basin effect might be observed during a potential excitation especially at the center of the plain accompanied by the thick soft sediments. These results indicate that local soil classification procedure should not be implemented by relying only on the shallow geotechnical and geophysical field testing da

Evaluation of site effect within the tectonic basin in the northern side of Ankara
Eker, Arif Mert; Kockar, Mustafa Kerem; Akgün, Haluk (2015-06-18)
This study mainly concentrates on the determination of site effects for the Plio-Quaternary and especially alluvial soils of the Cubuk district and its close vicinity in Ankara, Turkey. In the study area, particularly in the vicinity of the asymmetric graben that has formed due to the tectonic activities along the NE-SW trending normal faults, a microtremor survey was implemented to identify the local site response under a possible seismic event. The results were compared and correlated by using passive and...
Evaluation of Site Characterizations and Site Effects of the Ankara Basin Turkey
Koçkar, Mustafa Kerem; Akgün, Haluk (2007-06-28)
The purpose of this study is to assess the in-situ site characteristics and to perform seismic hazard studies of the Upper Pliocene to Pleistocene fluvial and Quaternary alluvial and terrace deposits located towards the west of Ankara. Based on a general engineering geological, geotechnical and seismic characterization of the site, site classification systems were assigned for seismic hazard evaluations. Then, short-period noise recordings of the microtremor measurements at the ground surface have been used...
A Comparison of Local Site Conditions with Passive and Active Surface Wave Methods
Akgün, Haluk; Koçkar, Mustafa Kerem (null; 2010-05-29)
This study encompasses dynamic soil characterization and seismic hazard mapping of the Plio-Quaternary and especially Quaternary alluvial sediments of the Çubuk district and its close vicinity that is situated towards the north of Ankara. The project site is located at a region which has a potential of being seriously affected by a possible earthquake occurring along the Çubuk Fault Zone that is thought to be a continuation of the Dodurga Fault Zone and a sub-fault belt of the North Anatolian Fault System t...
A 2800-year multi-proxy sedimentary record of climate change from Lake Cubuk (Goynuk, Bolu, NW Anatolia)
OCAKOĞLU, FARUK; Doenmez, Emel Oybak; AKBULUT, AYDIN; TUNOĞLU, CEMAL; Kır, Osman; Açıkalın, Sanem; Erayık, Cemal; Yılmaz, İsmail Ömer; Leroy, Suzan (2016-02-01)
The sediment of Lake Cubuk in NW Anatolia, which is situated very close to the climate boundary between the dry Central Anatolia and the wet Marmara region, is regarded as a suitable climate archive to test inward and outward movements of this boundary in accordance with past climate variations. Herein, we study the stratigraphic record of the last 2800years of this landslide-dammed lake at 1030m elevation, using multi-proxy tools (sedimentology, major and trace element geochemistry, stable isotopes, pollen...
Evaluation of site effects based on the 1999 Kocaeli and Düzce earthquake events and seismic microzonation of Gölyaka, Düzce, Turkey
YOUSEFI BAVIL, KARIM; Akgün, Haluk; Koçkar, Mustafa Kerem; Department of Geological Engineering (2022-2)
The high seismicity study area situated in a near-fault region in Gölyaka, Düzce, makes the determination of the bedrock geometry more complex, and hence, it makes this area very challenging in terms of a site response study that would aid a seismic hazard assessment. This study developed a basin model to evaluate the site effects in the tectonically controlled and formed Plio-Quaternary fluvial sediments of the Gölyaka region that uniquely falls within the bifurcated near-field fault section of the North A...
