N2 - An earthquake with a magnitude of MwCombining double low line7.5 that occurred in Sulawesi, Indonesia, on 28 September 2018 triggered liquefaction and tsunamis that caused severe damage and many casualties. This paper reports the results of a post-tsunami field survey conducted by a team with members from Indonesia and Taiwan that began 13d after the earthquake. The main purpose of this survey was to measure the run-up of tsunami waves and inundation and observe the damage caused by the tsunami. Measurements were made in 18 selected sites, most in Palu Bay. The survey results show that the run-up height and inundation distance reached 10.7m in Tondo and 488m in Layana. Inundation depths of 2 to 4m were common at most sites and the highest was 8.4m in Taipa. The arrival times of the tsunami waves were quite short and different for each site, typically about 3-8min from the time of the main earthquake event. This study also describes the damage to buildings and infrastructure and coastal landslides..
