| | Abstract | | We propose a technique to estimate subsurface structure with high accuracy using microtremor, gravity and magnetic data. Microtremor, gravity or magnetic data has been used for modeling subsurface structure, because their explorations are passive and not so difficult in field survey, also the results provide enough accuracy. However, it is difficult to determine subsurface structure model uniquely from single type of exploration data. In general, analysis, we employ rather reliable data such as boreholes or seismic reflection profiles to constrain uncertainty of the model. In this article, we analyze data obtained through two or more different types of explorations to improve accuracy of structural model. |
