Short summary

This study develops tsunami evacuation plan in Padang, Indonesia, known as one of the most affected areas due to the future tsunami events generated from the Sunda subduction zone. The evacuation plan is constructed using probabilistic earthquake source modelling considering all the uncertainty of the future events. The results show that probabilistic approach may produce comprehensive tsunami hazard assessments which can be used for building more reliable and robust evacuation plans.
