STUDY ON A PRE-ARRIVAL EARTHQUAKE DETECTION AND INFORMATION TRANSMISSION SYSTEM
|
´˜^i‰pjF
A newly developed real-time earthquake information system is presented. This system is composed of five earthquake detection stations, information center, and transmission devices for users. For data communication between the detection station and the information center, a network using packet-switched communication service has been installed. The system is simplified warning system which notifies users of the occurrence of an earthquake and its information such as location, magnitude and seismic intensity by announcement units and pocket pagers. The purpose of this study is to develop the early warning system for the practical use which provides information before a strong earthquake strikes. The results of this study will be possible to provide various applications for the future earthquake hazard mitigation depending on the users' objectives.
