EstuNet: Eskişehir ve Bursa Büyükşehirleri için Konumsal Veritabanlı Yeni Bir Zayıf/Kuvvetli Yer Hareketi Ağı, Batı Anadolu, Türkiye
Abstract
Eskişehir ve Bursa illerinde meydana gelebilecek büyük bir deprem, bölgenin ulusal ekonomiye endüstriyel katkısı, sosyo-ekonomik koşulları, endüstriyel üretim, yüksek nüfus gibi nedenlerden dolayı maddi ve manevi kayıplara neden olacaktır. Bu çalışmanın temel amacı, Eskişehir ve Bursa Basenleri içindeki yer tepkisi özelliklerinin ve dalga yayılım biçimlerinin belirlenmesidir. 26 adet sismometre ve ivmeölçerden oluşan EstuNet Sismik Ağı’nın Eskişehir ve Bursa Basenleri üzerindeki mekânsal dağılımı, yarım graben yapıdaki basen üzerinde farklı jeolojik formasyonlar ve farklı sediman kalınlıklarının yer tepkilerini ölçebilecek niteliktedir. İstasyonların konumları faylar, yerel zemin koşulları ve yerleşim yoğunluğu dikkate alınarak belirlenmiştir. Ayrıca bu istasyonlar aktif fay segmentlerinin yakınında konumlandırılmıştır. EstuNet Sismik Ağı kayıtları, depremin merkezinden istasyonlara gelen deprem dalgalarının varış zamanını ve yer hareketinin en yüksek ivme/hız (PGA/PGV) değerlerini göstermektedir.

EstuNet: A new Weak/Strong-Motion Network with Geodatabase for Metropolitan Eskisehir and Bursa, West Anatolia, Turkey
Abstract
A major earthquake induced financial and moral losses that may occur in Bursa and Eskisehir could be quite large for the reasons such as the high population, industrial production, socio-economic conditions and the industrial contribution to national economy of the region. The main purpose of this study, is to determine wave propagation and site response properties of both Eskisehir and Bursa Basins. EstuNet Seismic Network comprised 26 seismometers and accelerometers were spatially distributed in Eskisehir basin to represent the behaviors of different sediment thickness and different geologic formations of the half graben structured basin. The location of the stations was chosen according to faults, local soil conditions and settlement density. Also, these stations were located near the active fault segments. The recording on EstuNet Seismic Network Stations show the arrival time of the earthquake from the epicenter to the stations and the peak ground acceleration/velocity (PGA/PGV) values.
