摘要
On 28 September 201 & an A4W7.5 earthquake struck Palu, Indonesia, and caused a large number of deaths and economic losses. Seismic moment tensor solutions determined by different institutes consistently suggest that this earthquake is overall a strike-slip event. However, it caused an unexpected large-scale tsunami around the Palu bay area. Commonly, the displacements of hanging wall and foot wall of a strike-slip event are mainly in horizontal directions, and are considerably weak in vertical components. Since vertical deformations are critical for tsunami generations, it is necessary to identify whether the tsunami is related to the source process or not. For this purpose, investigations of the source process are needed [1].
