A 16-station strong-motion seismic monitoring network covering metropolitan Izmir and the surrounding region was established in July 2008. The seismic network was installed as a cooperative effort involving the Earthquake Research and Implementation Center (ERIC-DAUM) of Dokuz Eylül University (DEU, Izmir), the Earthquake Research Department (ERD) of the General Directorate of Disaster Affairs (GDDA, Ankara), the Izmir Metropolitan Municipality, and the Ministry of Public Works and Settlement. The project was funded by the Scientific and Technological Research Council of Turkey (TUBITAK) to collect strong-motion data for earthquake hazard assessment studies and to develop a real-time monitoring system in Turkey (Inan et al. 2007) to address public safety issues.
The network is critically important to addressing earthquake hazard issues in western Turkey, an area known to have historically damaging earthquakes. Izmir is the third largest city in Turkey in terms of population, industrial density, economic capacity, and contribution to the national economy, and the economic and human consequences of a damaging earthquake in the Izmir area would be significant.
A primary goal of this project is to acquire strong ground-motion data in order to understand propagation and site response characteristics of the Quaternary and Neogene sediments that underlie the Izmir metropolitan area and are thought to produce large site amplification and seismic hazard (Aydinoglu 2000; Masure et al. 2000). These data will complement laboratory data to characterize the properties of the soft soils underlying the Izmir metropolitan residential area so that engineers and architects can design appropriate earthquake-resistant structures for the region. This project is also a first step toward developing a “Rapid Response and Damage Prediction System” for metropolitan Izmir where near real-time strong ground-motion records can be used to compute ground-shaking maps showing the areas most strongly affected by earthquakes.
