Evidence for Holocene Earthquakes along the Húsavík-Flatey Fault in North Iceland: Implications for the Seismic Behavior of Oceanic Transform Faults Matrau, Rémi; Klinger, Yann; Thorðarson, Thorvaldur; Guðmundsdóttir, Esther R.; Avşar, Ulaş; Parisi, Laura; Fittipaldi, Margherita; Jónsson, Sigurjón (2024-03-01) Understanding the long-term seismic behavior of oceanic transform faults is challenging because their location underwater generally prevents the use of classical paleoseismological techniques. The Húsavík-Flatey fault (HFF...
Seismo-turbidites reveal locations of major earthquakes during the past millennium in the Gulf of Aqaba, southern Dead Sea Fault Bektaş, Zeynep; Avşar, Ulaş; Ribot, Matthieu; Klinger, Yann; Jónsson, Sigurjón (2024-03-01) Although ample historical and paleoseismological information is available on major past earthquakes along the onland part of the Dead Sea Fault, knowledge of the seismic behavior of its southernmost part in the Gulf of Aqa...
The Destructive Earthquake Doublet of 6 February 2023 in South-Central Türkiye and Northwestern Syria: Initial Observations and Analyses Mai, Paul Martin; Aspiotis, Theodoros; Aquib, Tariq Anwar; Cano, Eduardo Valero; Castro‐Cruz, David; Espindola‐Carmona, Armando; Li, Bo; Li, Xing; Liu, Jihong; Matrau, Rémi; Nobile, Adriano; Palgunadi, Kadek Hendrawan; Ribot, Matthieu; Parisi, Laura; Suhendi, Cahli; Tang, Yuxiang; Yalcin, Bora; Avşar, Ulaş; Klinger, Yann; Jónsson, Sigurjón (2023-04-01) On 6 February 2023, two large earthquakes with magnitude 7.8 and 7.6 rocked south- central Türkiye and northwestern Syria. At the time of writing, the death toll exceeded 50,000 in Türkiye and 7200 in Syria. The epicenter ...
A Paleolimnological Approach to Understand Regime-Shift Dynamics in Ladik Lake (North Turkey) Maraşlioğlu, Faruk; Soylu, Elif Neyran; Avşar, Ulaş; Hubert-Ferrari, Aurelia (2023-01-01)
Assessment of trace metal pollution in the coastal sediments of Fethiye-Go spacing diaeresis cek Bay (SW Turkey) and evaluation of pollution sources Gulsen-Rothmund, Halil Ibrahim; ARSLAN, ŞEBNEM; Kurtulus, Bedri; Tunca, Evren; Avşar, Ulaş; Avsar, Ozgur (2023-01-01) This research evaluated the trace metal pollution and the pollution sources in the coastal sediments of Fethiye-Go center dot cek Bay by using the spatial distribution maps, correlation and statistical analysis, which were...
Active Faults' Geometry in the Gulf of Aqaba, Southern Dead Sea Fault, Illuminated by Multibeam Bathymetric Data Ribot, Matthieu; Klinger, Yann; Jónsson, Sigurjón; Avşar, Ulaş; Pons-Branchu, Edwige; Matrau, Rémi; Mallon, Francis L. (2021-04-01) Detailed knowledge of fault geometry is important for accurate seismic hazard assessment. The Gulf of Aqaba, which corresponds to the southern termination of the 1200-km-long Dead Sea fault system, remains one of the least...
Active tectonics and kinematics of Fethiye-Göcek Bay, SW Turkey: Insight about the eastern edge of Pliny-Strabo Trenches Tosun, Levent; Avşar, Ulaş; Avşar, Özgür; Dondurur, Derman; Kaymakcı, Nuretdin (2021-04-01) © 2021 Elsevier LtdPliny-Strabo Trench (PST)is a Subduction Transform Edge Propagator (STEP) fault developed at the northern edge of the African oceanic lithosphere connecting the Aegean and Cyprian trenches in the eastern...
Evaluation of ecological changes in lake hazar (Elazig, Turkey) using diatom-based paleolimnological techniques Maraslioglu, Faruk; Soylu, Elif Neyran; Avşar, Ulaş; Hubert-Ferrari, Aurelia (2020-12-01) Sediment core samples (H002, H003, H005 and H006) recovered from the basin of Lake Hazar located in the South East Region of Turkey. Core sam¬ ples were collected from the four sampling stations by UWITEC corer to determin...
A 3800 yr paleoseismic record (Lake Hazar sediments, eastern Turkey): Implications for the East Anatolian Fault seismic cycle Hubert-Ferrari, Aurelia; Lamair, Laura; Hage, Sophie; Schmidt, Sabine; Cagatay, M. Namik; Avşar, Ulaş (Elsevier BV, 2020-05-15) The East Anatolian Fault (EAF) in Turkey is a major active left-lateral strike-slip fault that was seismically active during the 19th century but mostly quiet during the 20th century. Geodetic data suggests that the fault ...
Evaluating the thermal stratification of Koycegiz Lake (SW Turkey) using in-situ and remote sensing observations Kurtulus, Tugba; Kurtulus, Bedri; Avsar, Ozgur; Avşar, Ulaş (Elsevier BV, 2019-10-01) The goal of this study is to evaluate the thermal properties of Koycegiz Lake using in-situ measurements and satellite based thermal infrared imagery. In-situ measurements of surface water temperature and water depth, as w...
