“…Erzurum, the metropolitan city of the Eastern Anatolia of Turkey, is located in the seismically active main segment of the Erzurum Fault Zone (EFZ) in the Northeast Anatolian compressional area. The seismic activity of Erzurum is mostly controlled by Dumlu and Palandoken fault zones, characterized by the NE-SW trending faults on eastern margin, whereas the NE-SW trending reverse faults on the southern margins, associated with neotectonic deformations after Plio-Quaternary (Yarbasi and Kalkan 2009).…”

“…Several studies have been conducted in the study area within the earth sciences. The geological structure and tectonic evolution of Erzurum region and its surroundings have been mainly investigated by Keskin et al (1998), Yarbasi and Kalkan (2009), Kocyigit and Canoglu (2017). Moreover, there are some attempts associated with geothermal potential (Bektas et al 2007;Gulec and Hilton 2016), geochemical (Bayraktutan et al 1996;Keskin e al.…”

Erzurum and its surroundings are one of the seismically active and hydrothermal areas in the Eastern part of Turkey. This study is the first approach to characterize the crust by seismic features by using the local earthquake tomography method. The earthquake source location and the three dimensional seismic velocity structures are solved simultaneously by an iterative tomographic algorithm, LOTOS-12. Data from a combined permanent network comprising comprises of 59 seismometers which was installed by Ataturk University-Earthquake Research Center and Earthquake Department of the Disaster and Emergency Management Authority to monitor the seismic activity in the Eastern Anatolia, In this paper, three-dimensional Vp and Vp/Vs characteristics of Erzurum geothermal area were investigated down to 30 km by using 1685 well-located earthquakes with 29.894 arrival times, consisting of 17.298 P- wave and 12.596 S- wave arrivals. We develop new high-resolution depth-cross sections through Erzurum and its surroundings to provide the subsurface geological structure of seismogenic layers and geothermal areas. We applied various size horizontal and vertical checkerboard resolution tests to determine the quality of our inversion process. The basin models are traceable down to 3 km depth, in terms of P-wave velocity models. The higher P-wave velocity areas in surface layers are related to the metamorphic and magmatic compact materials. We report that the low Vp and high Vp/Vs values are observed in Yedisu, Kaynarpinar, Askale, Cimenozu, Kaplica, Ovacik, Yigitler, E part of Icmeler, Koprukoy, Uzunahmet, Budakli, Soylemez, Koprukoy, Gunduzu, Karayazi, Icmesu, E part of Horasan and Kaynak regions indicated geothermal reservoir.

“…The tower and the city are located close to Erzurum Fault Zone (EFZ), which is one of the most active fault belts of the East Anatolian region and is an intermountain sedimentary basin with a Miocene–Quaternary volcanic basement, andesitic–basaltic lava flows and fissure eruptions of basaltic lava. City of Erzurum is located in Karasu plain and on the central segment of the EFZ (Yarbasi and Kalkan, ).…”

Historical structures and preserving their cultural values are crucial issues for humanity, not only because of their link to important certain periods in the past, but also their unique architectural features. Although many historical structures continue to offer services while keeping their historical values, some of them are at high risk in seismic prone regions. Therefore, the understanding of their structural performance under strong ground motions has been of significant importance to the civil societies as well as engineering community. The structural systems of historical buildings, generally, consist of masonry walls or piers. The behavior of such walls is controlled by either deformation or force. Seismic performance evaluation of historical structures can be carried out within the framework of performance-based evaluation principles. This paper mainly discusses the basic principles to be considered in performance-based seismic evaluation of historical structures. Proposed seismic hazard levels, evaluation of existing seismic hazard, selection of earthquake ground motions as well as site geology, geological and tectonic settings of the area, seismic activity of the region and local soil conditions are needed for a thorough performance evaluation. Seismic performance evaluation of a clock tower located in eastern Turkey was accomplished based on the proposed principles.

Geotechnics has a significant contribution in the construction engineering and natural risks, by providing for many useful data to direct the regional planning and prevent catastrophes. The geotechnical cartography became imperative to satisfy the intensive requirement of data concerning the soil and the basement, which initiated the urban development, often anarchistic. Indeed the cartography in geotechnics is a very complex task, because information concerning the soil and the basement are diverse. Due to its coastal and touristic position, Bejaia is one of the promising cities of Algeria. The site, on which the city is erected, is as an amphitheater where the sea is the scene. Indeed, Bejaia is located on a site surrounded by mountains on the three sides, north-south -west and it faces the sea on the east, its extension requires the use of lands with broken topography, and lead to appearance of new urban zones. These were built without consulting the experts in the field of the civil engineering, particularly geotechnics. This article presents the geotechnical cartography of Bejaia city; which shows the preliminary results of the zone of study, based on existing geotechnical, geological and topographic data.
