Tsunami is an unpredictable disaster. However, efforts to anticipate the tsunami disaster must be done. This research is done based on the earthquake’s history around Kolaka. Based on the location of the point of an earthquake and coastal area in Kolaka City, a numerical simulation analysis was performed using CADMAS Surf 3D to predict the speed and wave height when tsunamis happen after the earthquake. The tsunami analysis indicates that the affected area is based on wave velocity, wave height and topography condition in the coastal area of Kolaka City. Spatial analysis is used to delineate the tsunami-affected areas in Kolaka City. Based on the delineation of affected areas, local governments can take other preventive measures such as making maps of tsunami-prone areas with attributes such as evacuation routes, safe areas, temporary evacuation sites, and so on.
