ABSTRACT
Majene Regency, specifically the Banggae Timur District, is at considerable risk of tsunamis due to its
coastal location and increasing urban density. This research evaluates the effectiveness of current
Temporary Evacuation Shelters (TES) using a spatial analysis methodology combined with location�allocation modeling. The methodology included tsunami inundation mapping utilizing historical data,
identification of building points, analysis of TES capacity, and modeling of service areas within a
maximum evacuation radius of 935 meters.The study concentrated on two specific TES: Prasamya
Stadium and the Majene Regency Police Station. Although both locations possess adequate capacity for
hosting evacuees, they are situated within high-risk tsunami inundation zones (5–6 meters), making
them inappropriate for safe evacuation. Spatial allocation modeling indicates that these TES
predominantly serve the western section of Banggae Timur District, resulting in considerable
underservicing of eastern coastal areas and increased risk. Of the 2,774 houses located within the
tsunami inundation zone, 1,506 are currently unserved by the existing TES. The findings highlight the
necessity of identifying and establishing new TES in safer, elevated areas with enhanced accessibility
to improve evacuation coverage and safety. This study emphasizes the importance of spatial modeling
in enhancing evidence-based disaster mitigation planning. It offers precise, data-driven insights for
optimizing emergency infrastructure and minimizing population risk exposure in urban areas susceptible
to tsunamis
