Discriminating earthquakes and blasts and determination of earthquake comprising active faults in The Eastern Black Sea region

In recent years Eastern Black Sea Region, many have been quarry blast, and these signals were recorded seismic stations. This situation is caused by blasting earthquake the contamination on catalogs. Seismicity of the region to determine properly needs to be differentiated with earthquakes of blasting quarry on catalogs. Blasting and earthquakes can be distinguished from each other in different ways. This distinction must be applied with different methods to be able to safely.In this study, the Department of Turkey's Eastern Black Sea (the region between 37.60-420 longitudes and latitudes 40.20-41.50) are distinguished from each of the earthquakes and quarry of blasting. Occurred between the years 2002-2010 for this, Bogazici University Kandilli Observatory and Earthquake Research Institute (BU-KOERI) and seismic events recorded at stations belonging to the Black Sea Technical University, day and night rate, S / P ratio and the time-frequency analysis methods are examined.As a result, the records of events are analyzed in this way is about 65% of the blast records. The observed in the land intense blasting, Of, Maçka, Yomra, Araklı, Rize and Gümüşhane at place in the great quarries. In the region between Giresun, Gümüşhane, Trabzon are recorded both blast and small earthquakes. The majority of earthquake observed at sea. Seismic events of the Black Sea offshore of the Black Sea Region and above is along the thrust zone.
