Abstract
The R & D of Seismic Emergency Information Transmission System has been conducted involving the latest progress in earthquake engineering with regard to estimation techniques on the hypocenter, fault and earthquake motion parameters and in information technologies. This system is the disaster management system which consists of user site and disaster information center and is capable of mutual information transmission through Inter-Net and walkie-talkie. The concept of the disaster management system which is adaptable with DiMSIS (Disaster Management Spatial Information System) developed by professor Kameda et al. of Kyoto University has been established. Based on this concept, a prototype system has been developed. This system has following functions, (1) compatible application both in usual condition and emergency time, (2) the decentralized independence, and (3) the integration of space and time information. The system can estimate the earthquake motion information with 500m square mesh in a local area and transmit in a few minutes. In the development of the system, seismometer network, surface soil database and amplification functions were prepared for the examination of system function. Demonstration against the Tokai area was carried out and the function was verified.
