Development of Alarm Network Using Earthquake Early Warning

Abstract eng:
In Mikawa area, the central area of Japan, many automobile plants and machine factories are locating there, unfortunately it is also one of the most risky regions for large earthquakes in Japan. The Disaster Prevention Research Center（DPREC）, Aichi Institute of Technology(AIT), Japan, has organized a consortium which composed of enterprises in this area in order to mitigate seismic disaster. One of main research topics of DPREC is to re-distributing the Earthquake Early Warning (EEW) system, which is developed by Japan Meteorological Agency. The system is used for seismic disaster reduction because it can provide prior information such as, workers-evacuation and stopping line-system and so forth before the generation of strong earthquake shaking. Another one is to estimates seismic intensity and send them to plants, factories and offices in Mikawa area through internet system before S-wave arriving. The DPREC also has installed a seismometer network in the area aiming at getting observed seismic intensity and compare it with estimated one.Besides, the PC monitor installed at a central office can display information, such as epicenter, magnitude, seismic intensity and arriving time which is estimated by EEW. It also can animate P and S-wave propagating front and display it. The DPREC get observed seismic intensities from observing sites through the web system and send back the map of seismic intensities to monitor at other sites at once. The re-distribute EEW system developed by DPREC, now, has been installed at about fifty factories and works for seismic disaster prevention successfully.
