Abstract
On-line real-time vibration monitoring system was developed in the Higashiyama campus of Nagoya University for environmental vibration caused by construction activities and traffics. 40 sensors are installed on the buildings with vibration-sensible facilities such as high voltage electron microscope and micro-circuit manufacturing device. Vibration data observed by the sensors are quickly transferred to EWS through LAN and stocked by the relational database management system. Wave figures are immediately sent to constructors' offices by a facsimile modem. The system is also effective as the highdensity earthquake observation system for relatively concentrated area with different soil conditions.
