Tsunami Disaster Risk Reduction Strategy in Ciletuh–Palabuhanratu UNESCO Global Geopark

Abstract

Indonesia’s tsunami-prone areas are primarily located in the Pacific Ring of Fire, where the collision of three active tectonic plates (Eurasia, Indo-Australia, Pacific) results in significant seismic activity. This geological condition places several coastal regions at high risk, particularly for earthquakes and tsunamis. One such area is the Ciletuh–Palabuhanratu UNESCO Global Geopark (CPUGG) in Sukabumi Regency. This study aims to develop a tsunami disaster risk reduction strategy for the region, using a quantitative descriptive method. The study finds that the tsunami disaster risk level in CPUGG is 0.64, indicating a moderate risk that borders on high. The proposed risk reduction strategies are categorized into three levels, focusing on government, community, business, and tourist preparedness. The findings highlight that most hazard and vulnerability indicators remain high, while tourist capacity and preparedness are at a moderate level. The strategies suggested by the study could serve as valuable input for mitigating tsunami risks in CPUGG.
