The 5 magnitude earthquake in the Marmara region served as a test for the Earthquake Early Warning System developed by the Kandilli Observatory. The system generated its first alert in 8.4 seconds.
The Earthquake Early Warning System developed by Boğaziçi University Kandilli Observatory and Earthquake Research Institute (KRDAE) is still under development.
The system produced its first warning in 8.4 seconds during the 5 magnitude earthquake that occurred off the coast of Marmaraereğlisi in Tekirdağ on October 2.
NEW STAGE IS CRITICALLY IMPORTANT
According to a statement from the university, KRDAE has entered a new phase in its Earthquake Early Warning System studies conducted in Marmara, one of Turkey's regions with the highest earthquake risk.
The work being carried out in Marmara, one of Turkey's high earthquake risk areas, is critically important for the implementation of infrastructure that can detect the fastest spreading initial waves of an earthquake and produce warnings within seconds.
DELAY TIME REDUCED TO 0.2 SECONDS
By renewing the data transmission infrastructure of the stations in Marmara, the delay time of signals reaching Kandilli has been reduced to 0.2 seconds. While real-time data is transferred to special early warning software, the software evaluates the location and estimated magnitude of the earthquake in real-time to generate warnings.
CONSTITUTED A REAL-TIME TEST
The earthquake that occurred in the Sea of Marmara constituted an important real-time test for the system.
After the seismic waves reached the land stations in approximately 5 seconds, the software produced the first warning signal in a total of 8.4 seconds through rapid analysis.
CURRENTLY LOADED ON 2,500 DEVICES
KRDAE has developed an iOS-based mobile application in collaboration with a software company to deliver early warning signals to users. The system's performance is measured through real earthquakes in a test group consisting of approximately 2,500 devices.
To ensure the effective use of the earthquake early warning system across the country, KRDAE has prepared a comprehensive development plan aimed at establishing new low-latency stations throughout Turkey, developing an Android application, and strengthening the software infrastructure that will allow early warning signals to reach a large number of users simultaneously.
With the completion of the studies, it is planned that Turkey's earthquake early warning capacity will significantly increase and the system will reach a wider user base.
PREVIOUSLY NOTIFIED THE EARTHQUAKE IN SINDIRGI
Boğaziçi University Kandilli Observatory successfully provided a warning for the 6.1 magnitude earthquake that occurred in the Sındırgı district of Balıkesir on October 27.
Prof. Dr. Nurcan Meral Özel, Director of Boğaziçi University Kandilli Observatory and Earthquake Research Institute, stated that the newly tested system provided a warning 37 seconds before the tremors were felt in Istanbul.
