| Summary: | The catastrophic Indian Ocean tsunami of 26 December 2004 raised a number of questions for scientist
and politicians on how to deal with the tsunami risk and assessment in coastal regions. This paper
discusses the challenges in tsunami vulnerability assessment and presents the result of tsunami disaster
mapping and vulnerability assessment study for West Coast of Peninsula Malaysia. The spatial analysis
was carried out using Geographical Information System (GIS) technology to demarcate spatially the
tsunami affected village's boundary and suitable disaster management program can be quickly and
easily developed. In combination with other thematic maps such as road maps, rail maps, school maps,
and topposheets it was possible to plan the accessibility and shelter to the affected people. The tsunami
vulnerability map was used to identify the vulnerability of villages/village population to tsunami. In
the tsunami vulnerability map, the intensity of tsunami was classified as hazard zones based on the
inundation level in meter (contour). The approach to produced tsunami vulnerability assessment
map consists of considering scenarios of plausible extreme, tsunami-generating events, computing
the tsunami inundation levels caused by different events and scenarios and estimating the possible
range of casualties for computed inundation levels. The study provides an interactive means to identify
the tsunami affected areas after the disaster and mapping the tsunami vulnerable village before for
planning purpose were the essential exercises for managing future disasters. |
