This research examines the integration of disaster mitigation into spatial planning in Indonesia, specifically focusing on the earthquake vulnerability of Kajai in Pasaman Barat Regency. The study aims to refine spatial planning strategies to enhance resilience and inform government policies, ultimately reducing disaster impacts and promoting sustainable recovery in high-risk areas. In Kajai, both primary data from field observations and secondary data from regional spatial plans were employed. The Ground Motion Prediction Equations (GMPE) method was utilized alongside GIS for spatial analysis, assessing earthquake hazards to improve disaster resilience. GMPE was selected due to the presence of the active Semangko fault and complex local geological conditions, which significantly affect ground motion in the area. The earthquake hazard map categorizes areas into five vulnerability typologies, with area distribution as follows: Stable zone (8,636.78 ha), Typology A (1,761.89 ha), Typology B (702.11 ha), Typology C (71.46 ha), and Typology D (16.42 ha). The most vulnerable zone, Typology D, is concentrated in the hamlets Lubuak Sariak and Tanjung Beruang. Despite being designated as an agricultural zone in the spatial development plan, Kajai lacks protected zones for earthquake-hazard areas, underscoring the need for integrating seismic risk into spatial planning to ensure community safety. ©2025 The authors.
