A Simulated Strong Ground Motion Database for Potential Earthquake Scenarios on North Anatolian Fault Zone
Öz
Strong ground motions, which are recorded by accelerometers at temporary
or permanent stations during earthquakes, vary depending on magnitude of the
recorded event, distance from the earthquake source to station and local site
characteristics of the station. These acceleration-time records are input
parameters used in different disciplines ranging from earth sciences to
earthquake engineering. Strong ground motion networks in the world and Turkey
are constantly expanding; thus, both the information on the sources of past
earthquakes and the studies on the Earth are increasing in number with the help
of different earthquake records. However, since the earthquakes of different
magnitudes do not statistically occur with the same frequency, there are
deficiencies even in the world's most developed networks. In other words, when
the entire potential seismic effects in a region is to be examined, there are
no records corresponding to some intensity values. This problem is more
evident for the ground motion networks in regions where no dense station
distribution is available. Nowadays, ground motion simulation studies are
becoming increasingly important all over the world. The main goals of this
study are to prepare a simulated earthquake ground motion database on the North
Anatolian Fault Zone which is the most active fault zone of Turkey; to
investigate the fundamental characteristics of this database, and to present
those features by comparing findings obtained from recorded ground motions.

Kuzey Anadolu Fay Hattı Üzerinde Olası Deprem Senaryoları İçin Benzeştirilmiş Bir Kuvvetli Yer Hareketi Veri Tabanı
Öz
Depremler sırasında oluşan ve ivmeölçerler tarafından
geçici ya da kalıcı istasyonlarda ölçülmekte olan kuvvetli yer hareketleri,
temel olarak, kaydedilen depremin büyüklüğüne, kaynaktan istasyona olan
mesafeye ve istasyonun bulunduğu (yerel) zemin özelliklerine bağlı olarak değişirler.
Bu ivme-zaman kayıtları, yer bilimlerinden deprem mühendisliğine uzanan farklı
disiplinlerde kullanılmakta olan girdi parametreleridir. Dünyada ve ülkemizde
bulunan kuvvetli yer hareketi ağları sürekli olarak genişlemekte; bu sayede
farklı deprem kayıtları ile hem geçmiş depremlere ait kaynak bilgileri hem de
yerküre hakkındaki çalışmalar sayıca artmaktadır. Ancak, farklı büyüklükteki
depremler istatistik olarak aynı sıklıkta meydana gelmediği için, dünyanın en
gelişmiş ağlarında bile kayıt eksiklikleri bulunmaktadır. Başka bir deyişle,
bir bölgede olası sismik etkilerin bütünü incelenmek istendiğinde bazı şiddet
değerlerine karşılık gelen kayıtlar bulunmamaktadır. Yoğun istasyon dağılımı
bulunmayan yer hareketi ağlarında ise bu sorun daha belirgin olarak ortaya
çıkmaktadır. Bu sebepler nedeniyle günümüzde yer hareketi benzetim çalışmaları
tüm dünyada giderek önem kazanmaktadır. Çalışmanın temel amacı; Türkiye’deki en
aktif fay hattı olan Kuzey Anadolu Fay Hattı üzerinde olası depremler için
benzeştirilmiş bir yer hareketi veri tabanı hazırlamak, bunun temel
özelliklerini incelemek ve bu özellikleri gerçek yer hareketlerinden elde
edilmiş bulgular ile karşılaştırmaktır.
