As we are trying to get a better understanding of how far the destruction potential in Mount Agung in the future. Using the data from the Indonesia Geospatial Agency, this is vulnerability area caused by the Mount Agung eruption.

Here are the locations of mostly visited tourism objects in Karangasem district. There are some tourism objects and their surrounding built up areas that will be potentially affected by the volcano eruption.

When it comes to disaster risk reduction (DRR), especially to reduce the disaster impacts for human being, we need participative action from the stakeholders ranging from local government, local communities, tourism operators, and the tourists themselves. Time and spots are the keys in succeeding evacuation when disaster happens. Hence, the isochrone visualization were available to help estimate the time needed to access the nearest evacuation post within 20 minutes.
