The results of measuring and analyzing micro tremor are shown as the graph of foulier spectrum. There many points which should be taken into consideration in reading the vibration characteristics. Micro tremor has a standard level decided by the geological characteristics, when the value is not so far from the standard, the superior frequency is related to the layer. On the contrary, the noise made by the car in the nearest picked has a bad influence on the analysis. I. By using experimental impact, the amplitude of the noise and the difference caused by the transmitting direction are investigated. II. The observations on the underground, the surface, the 1st, the 3rd and 5th floor of the building show the vibration characteristics of the building and moreover the characteristics of the micro tremor. III. The geographical features and the historical changes of the landscape of INUYAMA are investigated. And at the fan and the edge of the terrace cliff, the micro tremor is picked and analyzed.
