The western coast of Sumatra Island is highly susceptible to earthquakes, which have the potential to trigger tsunami hazards. Padang, the largest city along this coast, is particularly vulnerable to these seismic events. Therefore, it is crucial to implement tsunami mitigation measures, specifically coastal ecology-based strategies. This research aimed to compare the extent of tsunami runoff in Padang city using two different models. The first model simulated tsunami runoff based on the existing land cover conditions, while the second model optimized land cover conditions in line with coastal ecological suitability. The simulation results indicated that the model based on the current land cover conditions, predicted a tsunami inundation area spanning 3,231 hectares. However, by optimizing land cover conditions based on coastal ecology, the inundation area was reduced to 2,839 hectares. This shows the adoption of the coastal ecology-based modeling approach led to a reduction of 391 hectares in a tsunami inundation area. © 2023, BIOFLUX SRL. All rights reserved.
