All new buildings had to conform to urban design and building design standards. Like other countries ravaged by the 2004 tsunami, Indonesia is now linked to a tsunami detection system in the Indian Ocean. Enormous waves struck countries in South Asia and East Africa with little to no warning, killing 243,000 people. • When the shaking stops, gather members of your household and review your evacuation plan. is above a certain threshold.

Post-disaster, immediate rescue and relief measures including temporary sheltering soon after an earthquake until about 3 months later and re-construction and re-habilitation measures for a period of about six months two main components: a Bottom Pressure Recorder (BPR) and a Surface Buoy. The drawback of water can be a sign of caution. As a result of their long wave lengths, tsunamis behave as shallow-water
