Spatial Planning Strategy for Disaster Mitigation Based on Earthquake Risk Analysis Using Geographic Information Systems (GIS)

Abstract The utilization of Geographic Information System (GIS) technology in spatial planning for disaster mitigation is a novel approach to developing regional spatial planning documents in Indonesia, particularly in the Pidie Jaya district. This district is situated along the fault line on the island of Sumatra, a tectonically active zone highly susceptible to seismic activity. This research employs a methodology that integrates spatial data analysis, and GIS modeling to comprehensively understand the potential and impact of earthquakes in the area. Initial data used for analysis was sourced from the 2016 earthquake in Pidie Jaya district. The analysis results were incorporated into GIS to create precise and detailed maps depicting earthquake vulnerability and hazard. Subsequently, a meticulous spatial planning strategy is formulated, encompassing recommendations for land use, building standards, and disaster mitigation infrastructure. This strategy is designed to offer practical and effective guidance for local governments in reducing earthquake disaster risks and significantly contribute to formulating sustainable disaster mitigation policies. The findings of this paper are expected to provide a substantial contribution to earthquake disaster mitigation efforts, not only in Indonesia but also globally.
