Abstract

On September 28th, 2018, a tsunami triggered by strike-slip earthquake 7.5 Mw hit along Palu coast in Indonesia. Due to the tsunami, some harbors and their facilities, i.e. Wani, Pantoloan, Taipa, and Donggala ports were damaged by the destructive wave. The paper is aimed at identifying and classifying the damages around harbor complexes such as dock condition after it was attacked by the tsunami and drifted ships inland by interacting with tsunami force. Furthermore, along with the affected coast, we also found the destruction of seawall and revetment structures near the harbors. Based on these findings, the destructive characteristics of the tsunami waves on harbor elements were discussed. Two field works were conducted in Palu City and Donggala District during October 12–19, 2018 and November 16–23, 2018. In this paper, we reported and described the damage of four affected harbors mentioned above. The relation between tsunami flow depth and ships docked on land was also discussed in the paper.
