Earthquake Vulnerability Mapping Using Spatial and SWOT Analysis: A Case Study at Cisarua, Indonesia

Abstract

Cisarua District is a sub-district in West Bandung Regency that is prone to earthquake disasters. The Lembang Fault is the source of the main earthquake close to Cisarua District. This earthquake can cause negative impacts, such as the 28 August 2011 earthquake which caused damage to buildings in Jambudipa District. Mapping the level of vulnerability to earthquakes needs to be carried out to find out which areas are vulnerable physically, economically, socially and environmentally. Mapping the level of vulnerability to earthquakes uses spatial analysis in the form of an overlay that combines all indicators of vulnerability to earthquake disasters. Apart from that, this research also uses SWOT analysis to determine strategies that can be implemented to reduce the level of vulnerability to earthquake disasters. From the results of this research, it is known that of the 8 villages in Cisarua District, only 2 villages have high vulnerability to earthquake disasters, namely Jambudipa Village and Kertawangi Village. The area with high vulnerability in Jambudipa Village is 177,1754 Ha. Meanwhile, the village with the lowest threat level is Sadangmekar Village with a very low to low threat class. Based on the SWOT analysis, a suitable strategy to use in reducing vulnerability to earthquake disasters in Cisarua District is an aggressive and competitive strategy that prioritizes strengthening building construction, spatial planning based on disaster vulnerability, and preparing aid and access during disaster emergency response.
