SYNOPSYS

Seismic hazards can be defined as the probability of an earthquake occurring in a given geographic area, within a given window of time, and with ground motion intensity exceeding a given threshold, that may cause severe risk of damage as a result of seismic induced ground shaking. Apart from ground shaking, hazards from earthquakes include surface faulting or deformation (ruptures), liquefaction, tsunami and other cascading geological hazards suchas landslides and debris flow that is triggered by the earthquake. Hazard mitigation strategy of seismic risk depends on the nature and characteristics of the hazards. Some seismic hazard areas should be avoided and others can be resisted based on the geotechnical/engineering solutions.

A decision for selecting appropriate seismic hazard risk mitigation strategies is based on the holistic suitability assessment of a proposed development area, which include engineering geological assessment. During the assessment, all information pertaining to the earthquake event such as the interaction between tectonic plates, active faults and geological materials are taken into consideration. Tectonic plates may reveal the mechanism and source of seismic activities. Active faults disclose the probable location of rupture area, whereas geological materials may give some insight on the liquefaction area. Thus, this presentation is about seismic hazards and the risk assessment in geological perspectives and its application in selecting appropriate mitigation strategies.
