Tsunami risk reduction for densely populated Southeast Asian cities: Analysis of vehicular and pedestrian evacuation for the city of Padang, Indonesia, and assessment of interventions

In advance of a major tsunamigenic earthquake anticipated along the coast of West Sumatra Province of Indonesia, this study evaluates possible risk reduction interventions, particularly timely evacuation of the area. Interventions for tsunami risk reduction in Padang were analyzed through the development of a pedestrian and vehicular evacuation model and the assessment of strategies to improve evacuation rates. In Padang, the presence or absence of evacuation shelters has a significant impact on the evacuation rate in the first 30 minutes, and the structures' capacity can limit their effectiveness. The authors suggest that building a few high-capacity and high-resilience structures (such as evacuation hills) is more effective than constructing many small high-raised buildings. They also suggest that regulations for land use planning that consider tsunami risk should be established, preventing further urban development in areas that could be impacted by a tsunami.
