 Interest towards tsunami risks to Malaysia has also heighten since the 2004 Indian Ocean earthquake.Although the western coast of Peninsular Malaysia was largely shielded by the Sumatran island from the full effects of waves generated by the earthquake, weaker deflected tsunami waves led to damage and casualties along the northwestern coast of Peninsular Malaysia, affecting coastal Perlis, Kedah, Penang and Perak.The disaster also highlights the risk of further tsunamis that may strike coasts in direct line of undersea faults, primarily around the South China Sea.
