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

Annals of Geophysics, 2012
A linear finite-fault inversion procedure is applied to teleseismically recorded broadband P and SH velocity waveforms of the August 17, 1999, İzmit earthquake, to derive spatial and temporal distributions of the co-seismic slip over the representative ...

Seismic parameters re-determined from historical seismograms of 1935-Erdek–Marmara Island and 1963-Çınarcık Earthquakes

, 2016
In this study, the original seismograms of the 1935-Erdek–Marmara Island and 1963-Çınarcık Earthquakes, recorded at local and regional distances, were vectorized.

Gas Seepage along the Edge of the Aquitaine Shelf (France): Origin and Local Fluxes

Geofluids, Volume 2017, Issue 1, 2017., 2017
During the scientific expedition GAZCOGNE2 at the Bay of Biscay nine gas seeps were sampled for the first time and their flux was measured using an in situ pressure‐preservation sampler (PEGAZ, ©IFREMER). Overall, three sites were investigated to determine the nature and the origin of the gases bubbling at the seafloor and forming acoustic plumes into ...

Investigation of Soil Liquefaction Potential around Efteni Lake in Duzce Turkey: Using Empirical Relationships between Shear Wave Velocity and SPT Blow Count (N)

Advances in Materials Science and Engineering, Volume 2014, Issue 1, 2014., 2014
Evaluation of the liquefaction potential of a liquefaction‐prone area is important for geotechnical earthquake engineering, both for assessment for site selection and for planning and new constructions. The liquefaction potential index for the city of Duzce in northwestern Turkey using the empirical relationships between the Standard Penetration Test ...

Invasive insect genetics: Start codon targeted (SCoT) markers provide superior data to describe genetic diversity of brown marmorated stink bug, Halyomorpha halys, in a newly colonized region

Entomologia Experimentalis et Applicata, Volume 173, Issue 10, Page 1097-1111, October 2025.
In this study, we assessed the genetic diversity of Halyomorpha halys, an invasive agricultural pest, in Türkiye using start codon targeted (SCoT) markers and mitochondrial cytochrome c oxidase subunit I (COI) sequences. SCoT markers revealed high polymorphism (91.4%) and six genetic clusters among 71 specimens from 12 provinces, with Trabzon showing ...

Peak Ground Acceleration Prediction by Artificial Neural Networks for Northwestern Turkey

Mathematical Problems in Engineering, Volume 2008, Issue 1, 2008., 2008
Three different artificial neural network (ANN) methods, namely, feed‐forward back‐propagation (FFBP), radial basis function (RBF), and generalized regression neural networks (GRNNs) were applied to predict peak ground acceleration (PGA). Ninety five three‐component records from 15 ground motions that occurred in Northwestern Turkey between 1999 and ...

Rupture Directivity of Moderate Earthquakes Along the Main Marmara Fault Suggests Larger Ground Motion Towards Istanbul

Geophysical Research Letters, Volume 52, Issue 1, 16 January 2025.
Abstract Analysis of earthquake rupture directivity provides key information for seismic hazard and risk assessment, particularly for faults near urban areas. We analyze directivity patterns for 31 well‐constrained ML≥ ${M}_{L}\mathit{\ge }$ 3.5 earthquakes along the Main Marmara Fault, in direct proximity to Istanbul.

The Inherited Crustal Structure and Lithospheric Thermal Field Beneath the Sea of Marmara (NW Türkiye): Observations From 3D Gravity Modeling and Seismic Tomography Analysis

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 12, December 2024.
Abstract The North Anatolian Fault (NAF) extends for over 1,000 km across Türkiye and poses significant seismic hazard in the region. The Main Marmara Fault (MMF) segment of the NAF in the Sea of Marmara (NW Türkiye), exhibits along‐strike segmentation in its interseismic strain accumulation. Constraining the lithospheric configuration below the MMF is
