ABSTRACT
The natural hazard of tsunami has, for too long, been underrated as a potential cause of major disasters. However, several devastating tsunamis in and around the Pacific Ocean Basin over the last decade - all claiming significant loss of life, major property and environmental damage and severe socio-economic losses - have heightened the awareness of this natural hazard. As a consequence, significant mitigation strategies and measures in tsunami-prone regions of the world (such as the Pacific Basin, Mediterranean Region, Atlantic Ocean) have been undertaken in recent years. However, for the high tsunami risk Indonesian Region, a more considered approach needs to be addressed.Indonesia is a region with a considerable record of tsunami occurrence dating back hundreds of years. In a large number of these instances, devastating effects have been repotted. However, reliable and complete data bases, scientific analyses and integration of relevant information into disaster planning have been lacking. This paper reviews the status of available tsunami information (with particular reference to Indonesian and Japanese studies and the recently published Historical Tsunami Data Base for the US Pacific Coast UTDBIUS). presents a comprehensive data base (the central element to any tsunami hazard assessment) for the period 2000BC through 2001AD in the approximate region 9ON to IO’S, 104”E to 140”E and reviews available quantitative hazard and risk assessments. Comments are made on the integration of such assessments to the reduction of community vulnerability and to the prevention of potential damage (risk management) to major commercial development projects for the Indonesian region.
