The Role of Structural Tsunami Disaster Mitigation in Reducing the Impact of Future Tsunami Events in Indonesia

EasyChair Preprint 14998

Abstract

Today, the attractiveness of coastal areas has resulted in coastal communities continuing to grow, giving rise to new settlements, public facilities, port facilities, and tourism development. More than 40% of the world's population lives in coastal areas and more than 570 low-lying coastal cities will face a sea level rise of at least 0.5 m by 2050, public facilities, and residential areas due to extreme ocean wave activity will be lost, and become vulnerable to disaster threats, especially geological hazards of earthquakes accompanied by tsunamis. The growing potential of coastal areas will increase the vulnerability of several communities and supporting facilities to tsunami wave damage, resulting in considerable land destruction and loss of life. Indonesia is ranked second in the world as the country most frequently hit by tsunamis because geographically, the Indonesian archipelago is located in the border zone of three major Plates, namely the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate with high seismic activity that has the potential to generate earthquakes as the main effect of seismic activity and tsunamis as a secondary effect. Tsunamis occurring in the last 10 years are relatively rare because they occur unexpectedly, suddenly, unusually, and the biggest killer of people living in coastal areas against tsunamis. Although tsunami disasters cannot be avoided, their impact can be wisely mitigated through robust tsunami mitigation measures, as has been successfully demonstrated by several countries that have survived tsunami disasters. This is the background for conducting a tsunami disaster mitigation study with structural countermeasures (coastal protection and coastal forests) as a step towards building disaster-ready coastal communities in the near future.

Keyphrases: coastal forest, coastal protection, tsunami mitigation
