The local government in cooperation with the relevant parties had tried to minimize casualties before the disaster or during the disaster by making an evacuation route to the TES. The purpose of this study was to the mapping of TES and tsunami evacuation route using the approach of Geographic Information Systems (GIS) for disaster mitigation of tsunami-potential earthquake in north Pagai island.The research was conducted at 3 locations in the coast of Sikakap village, 4 locations in the coast of Taikako village, 3 locations in the coast of Silabu village, 7 locations in the coast of Saumanganya village, and 3 locations in the coast of Matobe village. The effort taken was to evacuate people to the TES with an average distance of 372.62 m from the beach. The results showed that the feasibility of TES that could accommodate residents, among others, were in the hills behind Sikakap Port, Taikako Silaoinan hills, the hills near the Mapinang Silabu village chief's office and Mapinang hills, Gulukguluk Saumanganya and Panatarat Matobe hills.
