The objective of this study is to account for this dynamic characteristic locality in the reclaimed land. In order for this, a large number of soil investigation data have been collected and a series of microtremor measurements have been conducted. From this study, it was found that: (1) the topography in the old times which is buried underground is the determining factor of the dynamic characteristics of the reclaimed land, (2) the predominant frequency corresponds to its scale, (3) the H/V spectrum has a sharp peak when the soil stiffness shows a remarkable change, (4) however, the spectral shape of microtremors does not have a sharp peak when the soil stiffness shows a gradual change.
