Kajian Potensi Tsunami Akibat Gempa Bumi Bawah Laut di Perairan Pulau Sulawesi
Abstract. From the middle of 1970’s until now, the Sulawesi Island which is surrounded by several small and big tectonic plates had been struck 270 times by earthquake above 5.0 in magnitude. This number of occurrence tends to get higher and higher each year, beginning after the raising activity of Sunda Arc past last six years, which recently struck Padang, West Sumatera in September 2009. The goal of this study is to find out the most potential areas for seismic and tsunamis activities in Sulawesi Island, by analyzing the historical data of earthquakes and tsunamis at the areas and also base on the simulation of several artificial tsunamis. It found out that the earthquakes with magnitude above 5.0 in the period of 2010-2020 will occur minimally 49 times; with almost all of them will be sea-epicentered which believe could generate tsunami on some areas. The most potential areas will be the North Arm of Sulawesi, especially in the coasts of North, South and East.
