Earthquake focal mechanism and stress tensor analysis along the central segment of the North Anatolian fault Karasözen, Ezgi; Özacar, Atilla Arda; Kaymakcı, Nuretdin; Department of Geological Engineering (2010) The North Anatolian Fault (NAF) is one of the world’s largest active continental strikeslip faults, and forms the northern margin of the Anatolian plate. Although its geologic and geomorphologic features are well defined, crustal deformation and associated seismicity around central segment of the NAF is relatively less-known. In this study, we analyzed locations and focal mechanisms of 172 events with magnitude ≥ 3, which are recorded by 39 broadband seismic stations deployed by the North Anatolian Passive ...
Earthquake Focal Mechanisms Along the Central Segment of the North Anatolian Fault Karasözen, Ezgi; Özacar, Atilla Arda; Biryol, C. Berk; Beck, Susan L.; Zandt, George (2010-05-02) The North Anatolian Fault (NAF) is one of the world’s largest active continental strike-slip faults, and forms the northern margin of the Anatolian plate. Although its geologic and geomorphologic features are well defined, crustal deformation and associated seismicity around central segment of the NAF is relatively less-known. In this study, we analyzed locations and focal mechanisms of over hundred events with magnitude ≥ 3, which are recorded by 39 broadband seismic stations deployed by the North Anatolia...
Earthquake Detection Near the Central Anatolian Fault Zone Using Continuous Data from the CD-CAT Experiment Russell, Joshua B.; Beck, Susan L.; Turkelli, Niyazi; Kalafat, Doğan; Özacar, Atilla Arda; Sandvol, Eric (2014-12-15) In central Turkey, the Anatolian plate is actively being pushed by Arabian plate convergence in the east and pulled by Hellenic arc retreat to the west; however, there is also ample evidence of internal plate deformation. This region provides an opportunity to gain a deeper understanding of the transition from collisional (eastern Anatolia) to escape tectonics (western Anatolia). The Continental Dynamics: Central Anatolian Tectonics (CD-CAT) experiment, consists of a dense array of 71 broadband seismometers...
Earthquake imprints on a lacustrine deltaic system: The Kurk Delta along the East Anatolian Fault (Turkey) Hubert-Ferrari, Aurelia; El-Ouahabi, Meriam; Garcia-Moreno, David; Avşar, Ulaş; Altinok, Sevgi; Schmidt, Sabine; Fagel, Nathalie; Cagatay, M. Namik (2017-08-01) Deltas contain sedimentary records that are not only indicative of water-level changes, but also particularly sensitive to earthquake shaking typically resulting in soft-sediment-deformation structures. The Kurk lacustrine delta lies at the south-western extremity of Lake Hazar in eastern Turkey and is adjacent to the seismogenic East Anatolian Fault, which has generated earthquakes of magnitude 7. This study re-evaluates water-level changes and earthquake shaking that have affected the Kurk Delta, combinin...
Earthquake generation cycles and tsunami simulations providing possible scenarios for Turkey Marmara sea and Japan Nankai trough and Japan trench Horı, Takane; Yalçıner, Ahmet Cevdet; Meral Özel, Nurcan; Kılıç, İrfan; Miyazaki, Shinichi; Hyodo, Mamoru (null; 2015-04-12) In order to obtain comprehensive earthquake and tsunami scenarios for disaster assessment, numerical simulations of earthquake generation cycles and resultant tsunami generations have been performed in Japan. The occurrence of the 2011 Tohoku earthquake has realized us the necessity to consider all the possible scenarios without preconceptions. We have performed large-scale numerical simulations using Earth Simulator and K-computer for earthquake generation cycles along the Nankai trough, southwest Japan, w...
