DEVELOPMENT OF ON-LINE DATA ACQUISITION SYSTEM FOR STRONG MOTION SEISMIC RECORDS AND ITS APPLICATION TO EXISTENT OBSERVATION SYSTEMS

Abstract

On-line strong motion seismic data acquisition system is developed and applied to existent strong motion and seismic intensity observation systems. Approximately 200 sites have been connected in Tokai district, which belong to local government, lifeline companies, universities and institutes. Some on-line connection techniques have been newly developed and used for existing systems with various hardware and software. Finally, some new aspects on network connection for strong motion observation are discussed.
