A large-scale resistivity imaging survey was performed in the acropolis area of Archaic Cnidos, south-western Turkey. This survey was a part of the geophysical studies conducted between 1999 and 2004. Two-dimensional resistivity data were acquired along a number of parallel lines using a pole-pole array. The data was processed using a 3D inversion algorithm based on a robust technique. We also applied shaded-relief processing to enhance the representation of the images of apparent-resistivity data and inversion results. In addition, the inverted resistivity data were visualized by a volumetric representation technique to display both the horizontal and the vertical extents of the archaeological structures. The inversion results revealed that a rectangular gridding pattern and a dense structuring existed in the depth range 0.35-1.5 m in the acropolis. Moreover, the bedrock was the base of the archaeological structures in the area. Based on the resistivity survey, four test excavations were carried out in various localities in the acropolis in 2004. These excavations yielded results supporting those obtained by the resistivity inversion. This indicated that large-scale 3D resistivity imaging can be a useful tool in archaeological prospection.

Site-specific uniform hazard spectrum in Eastern Turkey based on simulated ground motions including near-field directivity and detailed site effects Sisi, Aida Azari; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ (Springer Science and Business Media LLC, 2017-04-01) In this study, stochastic earthquake catalog of the Erzincan region in Turkey is generated based on synthetic ground motions. Monte Carlo simulation method is used to identify the spatial and temporal distribution of events. Ground motion time histories are generated using stochastic simulation methodology. Annual exceedance rate of each ground motion amplitude is calculated through statistical distribution of the complete set of ground motions. The results are compared with classical probabilistic seismic ...
Enhancement of the national strong-motion network in Turkey Gulkan, P.; Ceken, U.; Colakoglu, Z.; Ugras, T.; Kuru, T.; Apak, A.; Anderson, J. G.; Sucuoğlu, Haluk; Celebi, M.; Akkar, D. S.; Yazgan, U.; Denizlioglu, A. Z. (Seismological Society of America (SSA), 2007-07-01) Two arrays comprising 20 strong-motion sensors were established in western Turkey. The 14 stations of BYTNet follow a N-S trending line about 65 km in length, normal to strands of the North Anatolian fault that runs between the cities of Bursa and Yalova. Here the dominant character of the potential fault movement is a right-lateral transform slip. The DATNet array, comprising a total of eight stations, is arranged along a 110-km-long E-W trending direction along the Menderes River valley between Denizli an...
Unlocking the secrets of Al-tobermorite in Roman seawater concrete Jackson, M D; Chae, S R; Mulcahy, S R; Akgül, Çağla; Taylor, R; Li, P; Emwas, A-H; Moon, J; Yoon, S; Vola, G; Wenk, H-R; Monteiro, P JM (Mineralogical Society of America, 2013-10-01) Ancient Roman syntheses of Al-tobermorite in a 2000-year-old concrete block submerged in the Bay of Pozzuoli (Baianus Sinus), near Naples, have unique aluminum-rich and silica-poor compositions relative to hydrothermal geological occurrences. In relict lime clasts, the crystals have calcium contents that are similar to ideal tobermorite, 33 to 35 wt%, but the low-silica contents, 39 to 40 wt%, reflect Al3+ substitution for Si4+ in Q(2)(1Al), Q(3)(1Al), and Q(3)(2Al) tetrahedral chain and branching sites. Th...
Estimation of seismic losses in urban regions within an interdisciplinary framework a case study Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet; Asten, Michael; Karim Zadeh Naghshineh, Shaghayegh (2014-04-30) Abstract – The purpose of the study described in this article was to assess teachers’planning practices at the primary-school level in Turkey. Altogether 210 schools weresurveyed, a questionnaire was distributed to all teachers in these schools, and 1194teachers responded to the questionnaire. The results indicated that the main sourcesof influence on daily and unit plans are teachers’ experience, the national curriculumand the course textbooks. In daily planning, teachers ass...
Hydrogeochemical outline of thermal waters and geothermometry applications in Anatolia (Turkey) Mutlu, Halim; Güleç, Nilgün Türkan (Elsevier BV, 1998-10-01) The chemical compositions of a total of 120 thermal water samples from four different tectonically distinct regions (Central, North, East and West Anatolia) of Turkey are presented and assessed in terms of geothermal energy potential of each region through the use of chemical geothermometers. Na-Ca-HCO3, type waters are the dominant water types in all the regions except that Na-Cl type waters are typical for the coastal areas of West Anatolia and for a few inland areas of West and Central Anatolia where dee...
