摘要：
Constructing strong structures and facilities is an essential countermeasure in Earthquake Disaster Prevention (EDP). For railway systems, the safety of passengers from strong motion is a big concern regarding safety and stability of running trains. The EDP, in general, requires not only the hardware measures but also the software measures to minimize the influence of earthquake damage. In this paper, basic concepts of the EDP are described and the real-time earthquake information systems, UrEDAS, Urgent Earthquake Detection and Alarm System, and HERAS, Hazards Estimation and Restoration Aid System, are outlined. Furthermore, as the elementary techniques of these systems, investigation methods using PIC, Portable Intelligent Collector, and vulnerability indexes K values for surface of ground and structures are proposed.
