Abstract
The 26 December 2004 Andaman mega tsunami killed about a quarter of a
million people worldwide. Since then several significant tsunamis have recurred
in this region, including the most recent 25 October 2010 Mentawai tsunami.
These tsunamis grimly remind us of the devastating destruction that a tsunami
might inflict on the affected coastal communities. There is evidence that
tsunamis of similar or higher magnitudes might occur again in the near future in
this region. Of particular concern to Malaysia are tsunamigenic earthquakes
occurring along the northern part of the Sunda Trench. Further, the Manila
Trench in the South China Sea has been identified as another source of potential
tsunamigenic earthquakes that might trigger large tsunamis. To protect coastal
communities that might be affected by future tsunamis, an effective early
warning system must be properly installed and maintained to provide adequate
time for residents to be evacuated from risk zones. Affected communities must
be prepared and educated in advance regarding tsunami risk zones, evacuation
routes as well as an effective evacuation procedure that must be taken during a
tsunami occurrence. For these purposes, tsunami risk zones must be identified
and classified according to the levels of risk simulated. This paper presents an
analysis of tsunami simulations for the South China Sea and the Andaman Sea
for the purpose of developing a tsunami risk zone classification map for
Malaysia based upon simulated maximum wave heights.
Keywords: tsunami risk simulation, early warning system.
