Abstract

The relation between the predominant period of H/V spectrum ratio of microtremor and the layer thickness of the ground with different landform evolution was arranged and summarized in a relational expression. Effect of each landform evolution as to geomorphic provinces is reflected in the rational expression. The validity of the relational expression was then confirmed using actual ground motion records. When developing a hazard map of the ground, it is proposed to divide it into geomorphic provinces that show the same landform evolution as basic zoning data, and to subdivide the geomorphic provinces by the H/V spectrum ratio and sedimentary layer thickness.
