Integration of the Subsurface-Structure Model around Tsukuba Area, Ibaraki Prefecture, Estimated by H/V Spectral Ratio using Microtoremors.


Abstract
In this study, the Microtremor Survey was always inquired into after the geographical features geological features were examined enough, and the best surface velocity structure model from a peripheral basic structure to the surface was examined in a Tsukuba area. The microtremor measurement was executed about 200 points over around the Tsukuba Area. It was possible to explain, and a detailed speed structural model was able to be made about the excellence cycle about the Tsukuba Area. A detailed earthquake movement will be calculated by using this speed structural model in the future. The most appropriate amplitude will be calculated.
