GIS-based approach for evacuation safety place mapping in Da Nang city, Vietnam

摘要

Tsunami is a disaster which occurs in a short period of time but causes huge losses of life and property. Da Nang, a coastal city located by the East Sea of Vietnam is at risk of suffering from tsunamis. The city government built the first early warning system in 2015, functioning for citizens in the whole coastal region. However, there is a lack of an emergency evacuate plan for cases of warned disasters. This study aims to build an evacuation safety place map applying GIS-based approach to determine population distribution, transport system, and safety places. Results would be a useful tool to support to disaster risk management activities of Da Nang when a tsunami occurs.
