Abstract

Kolorai Village is a National Strategic Tourism Area (KSPN) influenced by complex tectonic activity. The low community resilience to earthquake disasters in Kolorai Village means that the government must refrain from using disaster risk factors as a reference in developing disaster mitigation-based tourism areas. This research aims to analyse the risk of earthquake disasters in the tourism area of Kolorai Village. Problem-solving in this research uses the survey method and descriptive analysis with a quantitative approach. Primary data or field data in the form of vulnerability and capacity data are obtained using the help of checklist instruments, questionnaires, and interviews. The earthquake disaster risk analysis results in Kolorai Village have a score of 3. They are included in the high category with a percentage of hazard factors of 43%, 28% vulnerability, and 29% capacity. The value of earthquake disaster risk is produced as a map that illustrates the elements of earthquake disaster risk in the Kolorai Village Tourism Area. So that it can be used for spatial planning, it needs to be integrated with disaster risk reduction.

Abstract

Earthquake hazard mapping in the North Maluku region is urgent and essential because this area has a very high earthquake hazard potential. The high level of earthquake vulnerability in the North Maluku region makes it very important to focus mitigation activities to reduce the impact of earthquakes that occur. Earthquake hazard mapping that illustrates the effects of earthquakes on an area is one of the disaster mitigation efforts. In this study, earthquake intensity using the Probability Seismic Hazard Analysis (PSHA) method will be used to analyse the level of earthquake hazard in the North Maluku region. The results of the distribution of Peak Ground Acceleration (PGA) values for North Maluku range from 0.67 - 3.75 g. At the same time, the value of the MMI earthquake intensity scale is in the range of IX-XII. The most incredible earthquake intensity is in the Morotai, West Halmahera, Ternate, Tidore, Bacan, and Obi Island areas. The results of this study can have implications as a reference in safer spatial and infrastructure planning, the preparation of more effective mitigation strategies, and can be a medium for educating the public to be more prepared and responsive to earthquake risks.
