Seismometer array system, a real time damage estimation system, and a shaking table system are unified efficiently at Nagoya University, all these systems are connected to a EWS through LAN and can be controlled on the EWS, As a result, data can be easily shared among the systems. Once an earthquake occurs, the seismic records obtained at 3 observation sites in the seismometer array system are sent immediately to the EWS. Using these records, first, the hypocenter and the magnitude of the earthquake, and then based on these seismic parameters the damage to the structures in Aichi prefecture is estimated spontaneously in the damage estimation system. An observed seismic record also can be used in an experiment for the dynamic behavior of a structure in the shaking table system. The records of an experiment are sent automatically to the EWS and can be easily analyzed.
