to Sulawesi governor to rename Palu Regency to Donggala Regency while keeping the capital in Palu as a compromise. Palu continued to outgrow Donggala, and the creation of Palu Administrative City and subsequent creation of Central Sulawesi province in 1964 with Palu as its capital further distanced Donggala from its past status. The province was established on 12 April 1964 due to demand from student groups for its creation to represent the region. The city gained administrative status in 1978 and kotamadya in 1994. On 28 September 2018, the city was hit by a devastating earthquake and tsunami. The city itself also experienced severe soil liquefaction. The liquefaction was the biggest in the world and caused massive destruction in parts of the city. The land where liquefaction happened is currently uninhabitable. In the aftermath of the disaster, several calls by politicians were made to relocate the capital city of Central Sulawesi away from Palu due to its vulnerability to earthquakes. The plan for city-wide relocation was made by the city government, dubbed Kota Palu Baru (New Palu City) was predicted to cost between five and six trillion of Rupiah. Affected areas of the earthquake are still being rebuilt, with progress only reaching 45% in May 2022 and predicted to last until the end of 2023. Ambiguity of land status outside city boundaries supposedly used for new housing for victims of the earthquake in particular hampered the relocation progress, and as many as 6,000 people still live in temporary housing in 2022. Geography The city of Palu is located in the Palu basin, close to Palu Bay, and lies directly on the Palu-Koro Fault. The basin is mostly composed of alluvial deposits of clay, silt, and sand, which were deposited by the flow of the Palu River from land above the valley. Alluvial sediments around the city are not consolidated and relatively young. The basement rock has been dated to the Cretaceous period. Below the layers of deposits, the rock in the region is mostly tertiary granite and granodiorite. The sediments are between depending on the location; sediments in the northern part of the city are thicker than those in the south because they are closer to the river's estuary. The Palu–Koro Fault runs for around through Palu Bay, cutting into the middle of the city, and is connected to a subduction zone in northern Sulawesi. The abundance of relatively weak
