Melonguane city is the capital of Talaud Islands Regency, North Sulawesi. Based on the tsunami potential map from BMKG, Talaud Islands fall into the category of high potential tsunami because of its location at the meeting of the Maluku plate and the newly discovered West Kawio Volcano in 2010. By mapping the risk of tsunami formation, and analyzing the areas of cities affected by tsunami by simulation, it can be found that the city area that has the highest risk of damage due to tsunami waves. Tsunami losses can be reduced by the development of city mitigation and good evacuation strategies. Coastal areas are developed into Tsunami wave damping areas such as the function of green space with tight vegtasi. The residential function is restricted, and also developed building points spread over a radius of 350m as an emergency evacuation site that can be reached by everyone within 15-25 minutes. The use of Tsunami hazard warning signs in high risk areas will increase population awareness, and with signs pointing directions to safe lanes and locations, will facilitate the evacuation process. In addition to emergency evacuation, the completeness of early warning plays an important role for early evacuation after the earthquake. With the development of a network of vehicle lanes to the highlands and also the development of pedestrian routes to the evacuation building (escape building) during the emergency evacuation. Evacuation and mitigation in the city can be carried out well through good early warning. Tsunami mitigation-oriented development can also be applied to similar areas based on risk analysis in the region.
