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 ...
8 January 2013 Mw=5.7 North Aegean Sea earthquake and its seismotectonic significance

Akin Kurcer; Yalçın, Hilal; Gülen, Levent; Dogan Kalafat (TAYLOR & FRANCIS LTD, 2015)

The deformation of the North Aegean Sea is mainly controlled by the westernmost segments of North Anatolian Fault System. On 8 January 2013, a moderate earthquake (Mw=5.7) occurred in the North Aegean Sea. A series of ...
A global approach to provide magnitude estimates for earthquake early warning alerts

Küyük, Hüseyin Serdar; Richard M. Allen (AMER GEOPHYSICAL UNION, 2013)

We examine five different methods to estimate an earthquake's magnitude using only P wave data for use in earthquake early warning systems. We test two input parameters: the maximum predominant period of the P wave ((max)(p)) ...
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 ...
Assessment of geothermal energy potential by geophysical methods: Nevsehir Region, Central Anatolia

Kıyak, Alper; Karavul, Can; Gülen, Levent; Ertan Peksen; A. Riza Kilic (ELSEVIER SCIENCE BV, 2015)

In this study, geothermal potential of the Nevsehir region (Central Anatolia) was assessed by using vertical electrical sounding (VES), self-potential (SP), magnetotelluric (MT), gravity and gravity 3D Euler deconvolution ...
Automatic earthquake confirmation for early warning system

Küyük, Hüseyin Serdar; S. Colombelli; A. Zollo; R. M. Allen; M. O. Erdik (AMER GEOPHYSICAL UNION, 2015)

Earthquake early warning studies are shifting real-time seismology in earthquake science. They provide methods to rapidly assess earthquakes to predict damaging ground shaking. Preventing false alarms from these systems ...
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 ...
Behaviour of brick infill walls strengthened with expanded steel plates

Altundal, Adil (SPRINGER, 2016)

The present study was dedicated to investigate an effective, economical and convenient method for strengthening brick infill walls, i.e. the use of externally-bonded expanded steel plates. A total of 30 plastered wall ...
Closure to "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.

Clustering Seismic Activities Using Linear and Nonlinear Discriminant Analysis

Küyük, Hüseyin Serdar; Yıldırım, Eray; Doğan, Emrah; Horasan, Gündüz (388 LIMO RD, WUHAN, CHINA MAINLAND 430074, PEOPLES R CHINA, 2014)

Identification and classification of different seismo-tectonic events with similar characteristics in a region of interest is one of the most important subjects in seismic hazard studies. In this study, linear and nonlinear ...

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 ...
Crustal thickness variations and isostatic disequilibrium across the North Anatolian Fault, western Turkey

A. W. Frederiksen; D. A. Thompson; S. Rost; D. G. Cornwell; L. Guelen; G. A. Houseman; M. Kahraman; S. A. Poyraz; U. M. Teoman; N. Tuerkelli; Utkucu, Murat (AMER GEOPHYSICAL UNION, 2015)

We use teleseismic recordings from a dense array of seismometers straddling both strands of the North Anatolian Fault Zone to determine crustal thickness, P/S velocity ratio and sedimentary layer thickness. To do this, we ...
Determination of coal layers using geophysical well-logging methods for correlation of the Gelik-Zonguldak and Kazpinar-Amasra (Bartin) coalfields, Turkey

Keskinsezer, Ayhan (SPRINGER HEIDELBERG, 2019)
