DEVELOPMENT OF EVALUATION SYSTEM FOR EARTHQUAKE MOTION USING A GEOGRAPHIC INFORMATION SYSTEM

Abstract

Following the Hyogo-ken Nanbu Earthquake, appropriate estimation for strong motions has become an important issue of earthquake-proof design. In this paper, on the basis of our concept for design support systems, we introduce a system developed to enable complex and repetitive tasks using past earthquakes, active faults and underground conditions for the evaluation of earthquake motions to be easily performed by a general design engineer. A geographic information system (CIS) which can simulate earthquake motions via the use of databases of information regarding past earthquakes, active faults and the properties of underground conditions, and which can produce reports in a standard format, is used as the core of the new system.
