A STUDY ON THE DYNAMIC CHARACTERISTICS OF THE SURFACE GROUND IN CHIBA PREFECTURE BASED ON LANDFORM CLASSIFICATION(Disaster)

The knowledge about the condition of the ground is a crucial factor that controls damage due to natural disaster. In order to acquire this knowledge, the authors have looked at the fact that the conditon of the ground is closely related to the landform. A method of obtaining landform classification was proposed in the previous study. This paper aims to evaluate amplification factors of the surface ground using landform classification. It was found in this study, landform has a significant influence on the amplification factor.
