23 October 2011 Van, Eastern Anatolia, earthquake (M (W) 7.1) and seismotectonics of Lake Van area

Utkucu, Murat (SPRINGER, 2013)

The 23 October 2011 Van earthquake took place in the NE part of Lake Van area, surprisingly on a fault (the Van fault) that is not present in the current active fault map of Turkey. However, occurrence of such a large ...
3D gravity modeling of Buyuk Menderes basin in Western Anatolia using parabolic density function

Işık, Mahir (PERGAMON-ELSEVIER SCIENCE LTD, 2009)

A method to model 3D sedimentary basins with parabolic density contrast is applied to Buyuk Menderes basin in Western Anatolia. The measured gravity fields, reduced to a horizontal plane, are assumed to be available at ...

A teleseismic finite-fault rupture model for the August 17, 1999, izmit earthquake (Mw=7.6): implications for the seismic nucleation phase

Utkucu, Murat; Durmuş, Hatice (IST NAZIONALE DI GEOFISICA E VULCANOLOGIA, 2012)

A linear finite-fault inversion procedure is applied to teleseismically recorded broadband P and SH velocity waveforms of the August 17, 1999, izmit earthquake, to derive spatial and temporal distributions of the coseismic ...
Active faulting geometry of the Aegean Sea from seismic reflection data

Saatçılar, Ruhi (1999)
An algorithm for Q-filtering

Saatçılar, Ruhi (1996)
Analysis of strong ground motion data from the Van earthquake (Turkey), 2011

Beyhan, Günay; Keskinsezer, Ayhan; Ozkan Kafadar (SPRINGER HEIDELBERG, 2019)

An earthquake of magnitude 6.6 (ML) and 7.2 (Mw) occurred at 13: 41 p.m. local time on October 23, 2011 in the western of the Ercek Lake and about 20 km away from the city center of Van, Turkey (EQE-KOERI in The October ...
Bala (Ankara) Earthquakes: Implications for Shallow Crustal Deformation in Central Anatolian Section of the Anatolian Platelet (Turkey)

Saatçılar, Ruhi (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2010)

Central Anatolia is quiet in terms of seismic activity, and rarely earthquakes up to magnitude 5.6 occur in the inner part of the Anatolian block or Anatolian platelet. Southeast of Ankara, the capital city of Turkey, two ...
Buried underground archaeological structures investigation with electrical method: diyarbakir Ulu Mosque (Turkey)

Karavul, Can; Nihan Arig; T. Fikret Kurnaz; Demirkol, Aşkın (NATL INST OPTOELECTRONICS, 2015)

The study area used as a temple during the pre-Christianity term, Mar Thoma Church after the adoption of Christianity and currently used as The Ulu Mosque. The most important feature of this mosque which has hosted many ...
Classification of seismic events using linear discriminant function (LDF) in the Sakarya region, Turkey

Budakoğlu, Emrah; Horasan, Gündüz (SPRINGER INTERNATIONAL PUBLISHING AG, 2018)

The Sakarya prefecture is an interesting area with various seismicity types. This activity comes from earthquakes occurring at the North Anatolian Fault Zone and from a few quarry blast areas in the region. These quarry ...
Clustering seismic activities using linear and nonlinear discriminant analysis

Yıldırım, Eray (2014)
Contamination of seismicity catalogs by quarry blasts: An example from Istanbul and its vicinity, northwestern Turkey

Horasan, Gündüz (PERGAMON-ELSEVIER SCIENCE LTD, 2009)

In this study, we investigated waveforms of 179 seismic events (1.8 < Md < 3.0) from the KOERI, NEMC digital database. We determined differences between earthquakes and quarry blasts based on time- and frequency-domain ...
Correlation between electrical resistivity and soil-water content based artificial intelligent techniques

Yıldırım, Eray; Yıldırım, Engin (ACADEMIC JOURNALS, 2010)

By using an artificial intelligent approaches, the purpose of this study is to compare water content of soils obtained from electrical resistivity in order to better results from conventional techniques system. The input ...
Coulomb static stress changes before and after the 23 October 2011 Van, eastern Turkey, earthquake (M-W=7.1): implications for the earthquake hazard mitigation

Utkucu, Murat; Durmuş, Hatice; Yalçın, Hilal; Budakoğlu, Emrah (COPERNICUS GESELLSCHAFT MBH, 2013)

Coulomb stress changes before and after the 23 October 2011 Van, eastern Turkey, earthquake have been analysed using available data related to the background and the aftershock seismicity and the source faults. The coseismic ...
Coulomb static stress changes before and after the 23 October 2011 Van, Eastern Turkey, earthquake (MW 7.1): Implications for the earthquake hazard mitigation

Utkucu, Murat; Durmuş, Hatice; Yalçın, Hilal (2013)
Crustal thickness variations and isostatic disequilibrium across the North Anatolian Fault, western Turkey
