Source parameters of moderate and strong earthquakes for Turkey and its surrounding area (1938-2017)

Kalafat D.

Kandilli Observatory and Earthquake Research Institute (KOERI), Boğaziçi University 34684 Çengelköy-Istanbul, Turkey:


The main goal of this study is calculating earthquake source parameters with inversion technique and preparing focal mechanism – moment tensor – faulting types data bank of Turkey and surrounding area and performing regional stress analysis. Source parameters–faulting mechanisms occurred in Turkey and surrounding area, compiling them and collecting in a complete data base in order to present the researchers attention from the date which the instrumental seismology started of 1938 until these days, consist the main work package of this research. This research was aimed to complete the previously made researches and updating of them. Approximately 70% of the fault parameters of all earthquakes were calculated within the scope of this study. Homogeneous and integrated data set preparation by calculating all missing parameters be-longing to previous earthquakes was aimed within the scope of research. We used fault parameters such as strike, dip, rake, seismic moment, moment magnitude, P and T axes azimuths and plunges for each earthquake. We prepared regional faulting types maps at regions belonging different tectonic regimes in Turkey by using faulting parameters. In this context, a total of 1950 earthquakes (Mw≥4.0) source parameters and fault plane solutions have been compiled and a large part of them have been calculated within the scope of the study.
