Numerical simulation of a tsunami from September 28, 2018, on Sulawesi Island (Indonesia) is carried out. It is shown that the observed distribution of tsunami heights within a large area can be explained by the direct effect of a strong earthquake, whereas in the source zone (area of the city of Palu) it was produced by an underwater landslide.
