This paper presents the result of estimation analysis of small earthquake data obtained from the Japanese wooden house built at Kawagoe campus of Toyo University. Earthquake sensors which are made for emergency alanning were installed to the experimental house so as to clarify their utility in health-monitoring of structures. Observing for about two years, we have obtained several data and have done spectrum analysis and hysteresis analysis. The experimental house was pulled by wires and slightly damaged in the middle of observation period. It is clear that the change of vibration characteristics of the house can be measured by small vibration data by earthquakes. Through observation and analysis, some important knowledge is obtained, which is used for a new observation system. The techniques of synchronizing sensor's clock, calculating accurate displacement and gathering data are needed for low-cost and effective monitoring system.
