A Comparison Study on the Infrastructure of National Seismic Networks

Abstract eng:
Distribution of national seismic networks is generally designed by seismologist’s experience. They are typically not optimized for various applications in engineering seismology such as earthquake early warning systems (EEWS). On the other hand, optimum performance can be achieved by investigating current station distribution, active faults and population of regions with the focus on EEWS. In this study, I investigated Turkey’s seismic station infrastructure and compared the station distribution with three region/country EEWS; California, Japan, and Switzerland. Region’s area and population together with area and population per station statistics are calculated. I explored the distribution of interstation distances within Turkey. I assigned an average interstation distance value, which is computed from the average distance to the three closest stations. From these values, I created contour maps of interstation distances using a linear interpolation between stations. The current distribution of stations in the Turkey’s network was not designed for EEWS purposes. The capabilities of an EEWS are primarily determined by station distribution. The distribution of station is currently not adequate for EEWS in Turkey. However, budget-limited reality, I proposed three strategies to improve seismic station density in this study.
