The objective of this study was to determine the location of vertical evacuation of buildings, a Temporary Evacuation Shelter – TES, in densely populated Palu urban area and along the Palu River by using network analysis.

   The Method of analysis was a network analysis within GIS environment. Using the previous study on children and elderly people walking speed ability, the research is creating scenarios within 5 minute walking distance to 30 minutes walking distance to the possibe TES Locations and evaluate the area served by TES.

   The result of this study has shown several vulnerable areas during the tsunami hazard and proposing the possibility of putting new TES-able location to be accessed by the most vulnerable groups, those are the children and elderly people.
