Review
On the 28th September 2018 at 17:02 local time, an earthquake of magnitude 7.5 Mw hit Indonesia, with epicentre located 78km north of the city of Palu on Sulawesi Island. The earthquake ground shaking triggered four substantial landslides and several instances of liquefaction and land subsidence. Furthermore, a localised tsunami was triggered in Palu Bay, likely due to subsea landsliding. These hazards caused damage to over 70,000 properties and the deaths of at least 4,438 people. The UK Earthquake Engineering Field Investigation Team (EEFIT) and Indonesian Tsunami and Disaster Mitigation Research Centre (TDMRC) conducted a joint reconnaissance mission to areas affected by the earthquake. This paper presents their main findings regarding these multiple hazards and their impacts on the built environment.
