  • Summary: The Mw 7.5 Palu earthquake occurred on September 28, 2019 at 6:02 p.m. local time caused significant structural and geotechnical damage in Central Sulawesi. Much of the damage along the coastal areas was caused by the tsunami. Details of the damage caused by the tsunami are described by Robertson et al. (2019) and Yalciner et al. (2018). Outside of the coastal areas, damage was primarily caused by flowslides, which occurred along the margins of the Palu Basin. All of the flowslides, with the exception of Balaroa, occurred near an irrigation canal, which provides water for irrigating rice fields. Three of these flowslides occurred within a zone of large ground deformation that extended for more than 6 km south of the Palu Airport.
