Disaster-Prevention System Using Information before S-Wave Arrival

摘要

With the establishment of intense earthquake observation networks, it is become increasingly possible to predict strong ground movement before earthquakes wave hit, enabling disaster prevention measures to be employed in advance. The development of prototype systems designed to make effective use of EEW through automated or semi-automated operations is also progressing steadily, with practical applications for registered users due to emerge in FY2006. However, issues still remain that need to be resolved before applications for indiscriminate people can be started. These issues must be resolved through collaboration between relevant organizations, and understanding and cooperation on the part of users. Service companies, organizations, and individuals need to get involved in order to find practical applications of EEW so as to minimize the damage which will be caused by large earthquakes that may occur at unexpected times. An important part of international cooperation too is the transfer of technology to countries where observation networks are not yet established.
