Earthquake Early Warning and Rapid Response System
Istanbul Metropolitan Area
GeoSIG has maintained a strong presence in countries where experts have reasons to suspect that likelihood of severe earthquakes has the highest risk of requiring interventions in the form of earthquake monitoring solutions.
GeoSIG has formed relationships with partners to ensure that earthquake monitoring systems provide the customer with solutions meeting output reporting requirements.
Istanbul, the demographic and economic heart of Turkey, has a 70% probability for an earthquake with a magnitude above 7.2 in the next 25 years. The infamous mega-city thus requires a system for Early Warning (EWS) for a safe shutdown of many important facilities and Rapid Response (RRS) for disaster management.
The scope of the system includes not only a turnkey, state-of-the-art metropolitan alarm basis but also the structural monitoring of historical and vital buildings towards a better understanding of seismic hazards in a populated and valuable geographical area by contributing to seismic data management systems.
152 Triaxial Accelerometers
152 Multichannel Recorders
(On Line / Dial Up / Off Line)
TEL-WLAN and TEL-SSR
2 System Operation Centres
4 Emergency Response Centres
The outputs of the EWS comprise of real time data streams from remote stations, processing of these streams and generating an earthquake alert of a destructive seismic earthquake, distributable to several institutions enabling vital information to be supplied to relevant officials and agencies.
The outputs of the RRS consists of processing of onsite seismic data continuously, seismic event triggered SMS messages from remote stations summarizing seismic event parameters, evaluation of incoming event parameters and processing these data to obtain damage estimation and event severity distribution across the metropolitan area, distribution of these results via real-time communication to relevant officials and agencies.
Overall outputs also include the monitoring and testing of the full system in use at periodical intervals.
