The microtremor measurement is one of the excellent methods to understand the dynamic characteristics of buildings and surrounding soil foundations. However, it is very difficult to extract only the information on the soil foundations from the measured data. It is assured in this study that signals included in the waves have a higher frequency of appearance comparing to the ambient noises. The authors have been conducting the microtremor measurement of the soil foundation in the low land area of the Arakawa basin as well as in the diluvial high land area extended to the south. Based on this assumption, a method in which the frequency characteristics is objectively evaluated by integrating properly treated spectra is proposed and applied in this study.
