Paper Title
Turkey's Seismicity and An Overview of Earthquake Studies
Abstract
Turkey is between three major tectonic plates, and compressed towards the north by Arabian and African plates. This region is the most active area of the Mediterranean region in terms of earthquake activity. Although a number of plates having different sizes on the region based on the spatial distribution of the seismicity, mainly three plate boundariesplayimportantroles [1].
These are the African, Arab and Eurasian plates. The Turkish/Anatolian plate is surrounded by African and Arabian plates in the south, the Eurasian plate in the north and the Aegean plate in the west. Relative motions between the African, Arabian and Eurasian plates account for most of the tectonic activity in theregion (Figure 1, [2]).
As a result, the Anatolian plate has a high danger for seismicity. This consists of the North Anatolian Fault Zone (NAFZ), East Anatolian Fault Zone (EAFZ) and SE Anatolian Thrust Zone which form the borders of the Anatolian Plate and important active fault segmentsthroughout Western Anatolia [3]. All these active faults cause a short time intervals intensive damages in Turkey earthquakes, which in turn is a significant risk of earthquake in Turkey (Figure 2, [3]).
For instance,Seismological studies reveal that the NAFZ is divided into 2 main branches in the Marmara Sea and that there are unbreakable segments in these branches. Therefore, the presence of seismic gaps in the region that can produce large earthquakes in the future has been revealed by seismological studies (Figure3-4).
