The seismicity of the northern part of Turkey is mainly controlled by the North Anatolian Fault zone (NAFZ). The NAFZ is one of the world's most active seismic zones, and has produced destructive earthquakes and related hazards in the northern region of Turkey. Several earthquakes and earthquake-related hazards have occurred along different segments of this fault zone in the recent past. The study area, Erbaa town, is located along the eastern segment of North Anatolian Fault Zone (NAFZ) and is one of the largest towns of Tokat Province in the Middle Black Sea Region of Turkey. The center of Erbaa is located on the left embankment of the Kelkit River. After the disastrous 1942 (M-s=7.2) and 1943 (M-s=7.6) earthquakes, the settlement was shifted southwards.


Spatial variations of active stress patterns and frequencymagnitude distribution of earthquakes in Western Anatolia, Turkey
Shah, S Tanvir; Özacar, Atilla Arda (null; 2018-04-23)
Western Anatolia is one of the most important tectonic elements of Turkey, and constitutes the eastern margin of Aegean Extensional Province. The area is one of the most seismically active continental margins around the globe experiencing N-S extension. Earthquake data in this study is used to analyze the active stress patterns and to estimate the earthquake return periods for different sub-regions in western Anatolia. Focal mechanism solution data is used for determining the orientations and ratios of prin...

The Madenkoy-Siir region lies in southeastern Anatolia, Turkey to the northeast of Siirt. The study area is in the southeastern Anatolian Thrust Belt, which forms the boundary between the Border Folds on the northern edge of the Arabian plate and the Taurids. In the region, limestones of the Midyat Group of Eocene-Miocene age and alternating marls and sandstones of the Lice Formation of Early-Middle Miocene age are the autochthonous units. Three thrust slices were emplaced over the autochthonous units durin...
Neotectonics of the southeast Marmara region, NW Anatolia, Turkey
Gürer, Ömer Feyzi; Kaymakcı, Nuretdin; Çakır, Şerafeddin; Kaymakcı, Nuretdin (Elsevier BV, 2003-7)
The North Anatolian Fault Zone (NAFZ) bifurcates into three branches in the Marmara Region, which is a transition zone between the strike-slip tectonics manifested by the NAFZ and the N-S directed extensional regime of western Anatolia. The southern Marmara region is characterized by the middle and the southern branches while the northern branch controls the north Marmara region. The south Marmara region is characterized by approximately E-W trending rhomb-like horst and graben complexes bounded by strike s...
Tectonic evolution of the Cretaceous Ankara Ophiolitic Melange during the Late Cretaceous to pre-Miocene interval in Central Anatolia, Turkey
Rojay, Fuat Bora (2013-04-01)
The chaotic tectonic belt, which is distinguished in northern Anatolia, is called the - Ankara Accretionary Complex - in the Ankara region, central Anatolia. The belt is differentiated into three imbricated tectonic subbelts, namely, pre-Triassic metamorphics, Melange with calcareous blocks and Cretaceous melange with ophiolitic blocks (Ankara Ophiolitic Melange).
Seismic strengthening of masonry infilled reinforced concrete frames with precast concrete panels
Süsoy, Melih; Tankut, Ali Tuğrul; Department of Civil Engineering (2004)
Over 90% of the land area of Turkey lies over one of the most active seismic zones in the world. Hazardous earthquakes frequently occur and cause heavy damage to the economy of the country as well as human lives. Unfortunately, the majority of buildings in Turkey do not have enough seismic resistance capacity. The most commonly observed problems are faulty system configuration, insufficient lateral stiffness, improper detailing, poor material quality and mistakes during construction. Strengthening of R/C fr...
