ADIBs: A Low-Cost Early Tsunami Warning System for Malaysia

Tsunami Warning System (TWS) consist detection and notification system that mostly operated by countries affected by Tsunami. For Malaysia, it is not cost effective to use cutting edge TWS. The reason is it free from big earthquakes where its location far from tectonic plate boundaries. Besides, it’s surrounded by neighbouring countries which act like natural wall to prevent natural disaster reach to Malaysia territory. Fatal Tsunami happened on 2004 has changed this fact and Malaysia is exposed to secondary effect of natural disaster happened at neighbouring countries. An earthquake with magnitude nine (9) occurred at Banda Aceh was generate Tsunami wave that propagate from Indonesia to Malaysia coastline killed 68 people. As an immediate action, Malaysian government introduce Malaysia Tsunami Early Warning System (SAATNM) which the technology behind the system is from imported equipment. Unfortunately, this sophisticated equipment is costly to maintain and it’s exposed to vandalise. Thus, ADIBs is acronyms for Aware Tsunami Detection Interconnected Built-In System is a TWS propose by authors to help Malaysian government agencies to develop a low cost and reliable TWS suitable for Malaysia usage. The authors also propose a novel method to calculate Tsunami risk which considers severity of Tsunami, occurrence of Tsunami and detection of Tsunami. Tsunami Failure Mode Effect Analysis (TFMEA) has successful informs Malaysia should focus on prevention works rather than using expensive TWS.
