The erosion is a very complex problem that can damage environmental ecosystems and land productivity. The main objective of this study is to predict soil erosion in Watutela watershed after the earthquake using GIS combination with the USLE method. The results showed that the erosion hazard index in the Watutela watershed was between the low to high criteria. The danger of high erosion was found in empty land about 427.93 tons/ha/year. While on the other hand, low criteria occurred in the

The results obtained allow determining as the Palu City development zone and to minimize the erosion hazard index, soil, and water conservation needs to be done through reforestation, rehabilitation utilization of tree architecture models that function in controlling erosion and climate, especially in high erosion hazard class.
