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 ...
Investigation of microseismic activity sources in Konya and its vicinity, central Turkey

Horasan, Gündüz (SPRINGER, 2011)

Different types of seismic activity were recorded in Konya, central Turkey, after the installation of broadband stations by the Kandilli Observatory and the Earthquake Research Institute (KOERI) in 2007. Fifty-nine seismic ...
Efficient multichannel filtering of seismic data

Saatçılar, Ruhi (1990)
Detection of causative bodies by normalized full gradient of aeromagnetic anomalies from east Marmara region, NW Turkey

Keskinsezer, Ayhan (ELSEVIER SCIENCE BV, 2008)

There are lithological and structural diversity of rock units underlying the East Marmara region, NW Turkey. The 3-D NFG method has been applied to aeromagnetic data in the study area. We have also used the Euler deconvolution ...
Seismic behaviour of the North Anatolian Fault beneath the Sea of Marmara (NW Turkey): implications for earthquake recurrence times and future seismic hazard

Utkucu, Murat; Sünbül, Fatih (SPRINGER, 2009)

Possible long-term seismic behaviour of the Northern strand of the North Anatolian Fault Zone, between western extreme of the 1999 A degrees zmit rupture and the Aegean Sea, after 400 AD is studied by examining the historical ...
Field experiments on wave propagation and vibration isolation by using wave barriers

Çelebi, Erkan; Fırat, Seyhan; Beyhan, Günay; Çankaya, İlyas; Vural, İsa; Kırtel, Osman (ELSEVIER SCI LTD, 2009)

In this paper, the obtained results from the experimental Studies describe the basic characteristics of wave propagation and ability of possible measures to reduce the impact of soil vibrations on structural response for ...
Structural Setting of the Northeastern Biga Peninsula (Turkey) from Tilt Derivatives of Gravity Gradient Tensors and Magnitude of Horizontal Gravity Components

Keskinsezer, Ayhan (SPRINGER BASEL AG, 2008)

The tilt derivatives from GGT and MHC over the northeast of the Biga Peninsula in northwestern, Turkey are interpreted to image the edges of geological structures. Tilt derivatives provide a quick method which works well ...
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 ...

The active main Marmara fault: comparative anatomy of a continental transform fault in a marine setting

Saatçılar, Ruhi (1900)
Mechanical and physical properties of the Kandira stone, Kandira, Turkey

Arman, Hasan; Ramazanoğlu, Şefik; Akıncı, Akın (SPRINGER HEIDELBERG, 2007)

Kandira stone, extensively used for building stone in northwest Turkey, consists of approximately 91% calcium carbon and 9% clay minerals. The mechanical and physical properties are reported. It is of note that the Brazilian ...
S-wave attenuation in the Sea of Marmara, Turkey

Horasan, Gündüz (ELSEVIER SCIENCE BV, 2004)

This paper presents the estimates of frequency-dependent attenuation of S-waves for five different regions of the crust in the Sea of Marmara. The estimation method for the S-wave attenuation is based on the rate of decay ...
