Indonesia is an area of active tectonics, surrounded by 4 main tectonic plates, the Indo- Australian Plate, the Pacific Plate, Philiphines Sea Plate and the Eurasian plate. Indonesia has experienced thousands of earthquakes and hundreds of tsunamis in the last hundred years. One of the most destructive earthquakes is Palu-Donggala earthquakes on September 28, 2018. This earthquakes produce strong ground shaking, tsunami and massive liquefaction. At least 2,000 people were passed away of the natural disaster. Magnitude of surface offset due to the main earthquake is estimated to 5 meters, but there has been no research related to the pattern of displacement from GPS observation. In order to explain the magnitude and pattern of deformation in every epoch, kinematic GNSS method is used in this research. The highest magnitude of the displacement is 0.0624 m at CTOL station, while the smallest is 0.0046 m detected at CKEN station. Displacement pattern from kinematic GPS analysis shows that Palu- Donggala Earthquake was caused by left-lateral motion of Palukoro Fault.
