Vulnerability factor in earthquake risk assessment model for roads in Indonesia

Abstract

Indonesia is one of the prone countries to natural disasters. The road is one of the infrastructures affected by the disaster. Natural disasters that contribute to road damages are earthquakes, landslides, and floods. One of the factors affecting disaster risk is a vulnerability. The higher the vulnerability, the possibility of damage and loss will be higher. Vulnerability indicators for roads will be assessed in this study. The Earthquake Disaster Risk Index is adopted in this study. The physical and economic vulnerability are the factor components that identified in this study. Indicators are selected by valid, reliable, data availability, objective, quantified, and directly influence the risk. The indicators are analyzed using Analysis Hierarchy Process in order to get the weight. There are 9 (nine) indicators selected as part of physical vulnerability.
