The North Sulawesi Subduction is one source of tsunami-generating earthquakes for areas located on the north coast of the north arm of Sulawesi. This subduction zone was formed due to the collision between several tectonic plates, such as the Pacific Plate, the Philippine Sea Plate, and the Eurasian Plate. The North Sulawesi Subduction zone is tectonically highly active and has the potential to cause earthquakes that can cause tsunamis. Historical records of tsunamis state that several tsunamis have struck the area around this zone. This study aims to estimate the tsunami run-up and the time of tsunami wave propagation on the north coast of North Arm Sulawesi, especially the Poigar and Tanamon beaches in South Minahasa Regency due to the North Sulawesi Subduction earthquake. Data was collected from various catalogs and other literature studies to determine input parameters such as earthquake source parameters, bathymetric data from GEBCO, and DEM (Digital Elevation Model) SRTM 1 arc-second topographic data. Data processing was carried out using TUNAMI N2 software with an 8.5 Mw earthquake scenario. The simulation results show that the estimated run-up of a tsunami that can hit the Poigar and Tanamon beaches varies widely around 2.38 – 2.69 meters, while the time for the tsunami waves to propagate from the earthquake source to the coast is about 23 – 26 minutes after the main earthquake.
