Abstract
Natural disasters cause damage and have an impact on economic, social and environmental aspects. West Bandung Regency has the highest number of natural disasters in the type of landslide disaster, occurring 52 times in the period 2008-2016 or 68%. The purpose of this study is to identify areas with potential mining resources- and Analysis of potential disasters to mitigate economic losses. The research methodology is literature study, field survey, mapping of disaster locations, mapping of damage to disaster areas, data processing, and analysis. The results of this study are high ground movement susceptibility zones spread throughout the West Bandung Regency but only occupy a small part of the area of each sub-district. In the Cisarua, Parongpong, and Lembang areas, this zone is generally located on the slopes of Mount Tangkubanperahu with a slope of more than 45%. The correlation coefficient is 0.765. The value of the coefficient of determination is 0.585 x 100%, which is 58.5%. This means that the ability of vulnerable areas and the number of people exposed to predict the total loss is 58.5%, so the remaining 41.5% of the variance of the total loss is explained by other variables.
