| | Abstract | | Estimation of subsurface structure using microtrmor are array microtrmor survey or law of quarter wavelength using microtrmor H/V. However, these method to suppose that subsurface atructure is 1d not necessarily the case that estimation precision is in the right at uneven ground. This study is development new method that is inversion of microtremor H/V for determining 2d subsurface structure. The results of numerical experiment estimated the shape of 2d subsurface structure is more high-precision than conventional method (law of quarter wavelength using microtrmor H/V). While microtremor observation data at Zushi area apply to new method. In the result, applicability of new method was confirmed for field data. |
