本研究では,強震および常時微動観測に基づいて,福井県の主要都市周辺の精度と信頼性の高い三次元地盤構造を求めることを目的としている.はじめに,常時微動が表面波に起因していると仮定し,微動観測データを再現できるS波速度構造の推定法の定式化を行った.次いで福井県内の平野ならびに既存断層周辺で,常時微動の一点三成分観測およびアレイ観測を高密度に実施しS波速度構造の推定を行い,対象領域の三次元地盤構造を算出した.

The purpose of this study is to determine the accuracy and reliability of weekly weather data in major cities of Fukui. In this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, strong earthquake The cause of the surface wave of the micro-motion is determined, and the speed of the S-wave is determined by the method of deduction of S-wave velocity. In the sub-Fukui Fukui, the cycle is broken, and 1.3 components are used to determine the speed of S-wave in high density. in the image field, the three-dimensional model is used to calculate the temperature.
