| | Abstract | | In this study, a detailed microtremor inquiry is executed in respect in the whole area part of Niigata Prefecture, and it is examined to upgrade an existing ground model from the S wave velocity structure of the obtained ground and the H/V spectral ratio by a single point of the microtremor the inquiry in the microtremor array the purpose is to examine it concerning the ground amplification characteristic in detail. In this report, it proposed the microtremor measurement point arrangement, the observation development, and the method for analyzing, to upgrade an existing ground structural model etc. based on the microtremor measurement result in Niigata Prefecture that had executed it last year. Moreover, Shallow and deep integration ground structural model making technique that matches the microtremor inquiry result by a single point are examined. |
