Multi-hazard assessment extends the traditional disaster hazard assessment. It provides an exhaustive view of disaster hazard management where all possible disasters are observed. More importantly, the interaction and compounding impact of the concurrent disasters event should be understood thoroughly. Up until now, hazard assessments of all possible disaster events in DKI Jakarta are estimated separately. This study aimed to initiate a multi-hazard assessment of earthquake and flood for urban areas in DKI Jakarta. A scenario-based of a concurrent disaster event is created, that is the sequence of earthquake and flood occurrence, and its impact are studied using multi criteria analysis. The evacuation shelters are proposed within the affected area and the shortest path for disaster reliefs are estimated using the shortest path algorithm. The area with high level multi-hazard should carefully plan their disaster mitigation and recovery management to prepare the society for the concurrent disaster event and ensure their resiliency.
