SOME PROBLEMS RELATED TO ENGINEERING GEOLOGY IN EARTHQUAKE HAZARD ASSESSMENT AND PREDICTION

Abstract

In the first part of this paper a variety of failure modes of earthworks in an earthquake are presented, where effects of subsoil conditions are explained. It is emphasized that a consideration for the individual mode is important in hazard assessment. In the second part earthquake faults in Japan are described briefly and the significance of active-fault mapping is discussed in view of the present state of sciences of hazard assessment and earthquake prediction.
