Seismic Risk Assessment and Mitigation: Case Study Malaysia

As observed from past earthquakes, industrial facilities are exposed to as much risk as building structures. Facilities such as large storage tanks, pipelines, transmission lines and precision machinery are particularly susceptible to damage that can lead to huge economic loss and environmental disaster. With high residential and population densities in urban areas where there are concentrations of industrial facilities, seismic risk and vulnerability assessment becomes even more important.

Work at the university of Sheffield has led to the development of a basic Earthquake Risk Assessment for low to medium seismicity regions (Kythreoti, 2002– case study Cyprus) and is currently being extended to cover medium to high seismicity regions by Shaukat Khan (case study Pakistan). This study aims to extend the Earthquake Risk Assessment framework by considering seismic risk assessment models for industrial facilities.

Malaysia is selected as the case study for this research project. Despite the fact that Malaysian peninsular is located in a tectonically stable intraplate environment, seismic risk assessment is still one of the important issues that should be considered when evaluating existing industrial facilities since industrial facilities should be examined as a system and not as independent structures.

A comprehensive spatial analysis will be performed in a GIS environment and carried out in the initial stage of the work to develop the seismic hazard map of the study area. Subsequently, a vulnerability analysis of the existing industrial structures will be conducted by implementing the framework previously developed at the University of Sheffield. The results will be used to perform a seismic risk analysis and estimate damages that could be caused by future earthquakes. Finally, earthquake mitigation strategies will be developed and recommendations for seismic strengthening of existing vulnerable industrial facilities in Malaysia will be given.

The results of this study will benefit decision makers in Malaysia, insurance companies, structural engineers and anyone who might be interested in seismic hazard, mitigation strategies and seismic strengthening of industrial facilities.
