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 ...
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 ...
Characterization, source and risk assessments of sediment contaminants (PCDD/Fs, DL-PCBs, PAHs, PCBs, OCPs, metals) in the urban water supply area

Guzel, Baris; Canli, Oltan; Celebi, Ahmet (2022)

Water resources are becoming more valuable day by day. They need to evaluate the pollution and risk situations of the sources that supply water in detail. It is aimed to determine the level of POPs (PCDD/Fs, DL-PCBs, PAHs, ...
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 ...
Crustal-scale shear zones and heterogeneous structure beneath the North Anatolian Fault Zone, Turkey, revealed by a high-density seismometer array

Utkucu, Murat; Gülen, Levent (ELSEVIER, 2015)

Continental scale deformation is often localised along strike-slip faults constituting considerable seismic hazard in many locations. Nonetheless, the depth extent and precise geometry of such faults, key factors in how ...
Evaluation of the effects of land-use change and increasing deforestation in the Sapanca Basin on total suspended solids (TSS) movement with predictive models

Temiz, Temel; Sonmez, Osman; Dogan, Emrah; Oner, Adnan; Opan, Mucahit (2022)

Sapanca Lake is a tectonically sourced freshwater resource and one of the rare natural water resources used as a source of drinking water. This study examined the change of land use and lake area in the natural water source ...
Geology of the Caldiran Fault, Eastern Turkey: Age, slip rate and implications on the characteristic slip behaviour

Erturaç, Mehmet Korhan (ELSEVIER SCIENCE BV, 2016)

The Caldiran Fault is a strike slip fault with a dextral slip in East Anatolia. The activity on this fault was marked by the November, 241976 earthquake (Mw: 7.1) which produced an similar to 50 km long surface rupture and ...
Multi-disciplinary earthquake researches in Western Turkey: Hints to select sites to study geochemical transients associated to seismicity

Saatçılar, Ruhi (VERSITA, 2010)

Warm and hot spring water as well as soil gas radon release patterns have been monitored in the Aegean Extensional Province of Western Turkey, alongside regional seismic events, providing a multi-disciplinary approach. In ...
New constraints on micro-seismicity and stress state in the western part of the North Anatolian Fault Zone: Observations from a dense seismic array

Utkucu, Murat; Gülen, Levent (ELSEVIER, 2015)

With the aim of extensively investigating the crustal structure beneath the western segment of the North Anatolian Fault Zone where it splays into northern and southern branches, a temporary seismic network (dense array ...
Optimal Seismic Network Density for Earthquake Early Warning: A Case Study from California

Küyük, Hüseyin Serdar (SEISMOLOGICAL SOC AMER, 2013)
Seismological investigations of fireworks factory explosions in Hendek-Sakarya (Turkey)

Budakoglu, Emrah (2022)

On July 3, 2020, a sequence of explosions occurred in the Hendek fireworks factory in Sakarya, Turkey. The explosion caused great material damage and loss of life. In this study, seismic and acoustic waves related to the ...
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 ...
