DEVELOPMENT OF AN INTEGRATED GEOPHYSICAL AND GEOLOGICAL INFORMATION DATABASE FOR STRONG-MOTION EVALUATION
We develop an integrated geophysical and geological information database of the whole of Japan for strong-motion evaluation. Once simulation of strong-motion concerned, we need a seismic velocity-structure with an attenuation model to evaluate strong-motions. In order to model velocity-structure for strong-motion evaluation, we have to consider a deep underground structure down to the earth crust, or to the plate boundary, up to a seismic bedrock, then to a structure of an engineering bedrock layer, and final to a structure of surface layers. In our study, we use various available data in all of Japan and build a database by integrating such information. Standardizing and integrating different kinds of data such as geological data and physical value data, we develop the dispersion-managed type network system to open each database distributed to each organization and utilize them each other. In order that many organizations can join the database, cutting the cost of installation, operation and maintenance fee of the system and securing mutual exploitation of data are desired. The management system on sharing databases is developed by the following concepts. i) Some open source software is adopted to cut the initial cost. ii) One organization runs a portal site, and others are responsible only for their own database. iii) Adopting the world standard, this system is more compatible with others or GIS software.
