Micro-zonation maps: Vulnerability mitigation earthquake of central Sulawesi Province for planning purpose high activity infrastructure building

Ground movement has been analysed according the pattern of peak ground acceleration (PGA), peak ground velocity (PGV) and peak ground displacement (PGD) due to the earthquake case study of earthquake Palu and Donggala, Central Sulawesi regency in 2009 to 2018 for disaster mitigation purposes on buildings infrastructures planning development. Earthquake data are histories seismic data with magnitude of 4 and above. The data were analysed using the developed formula by Wu and Zhao to obtain the relation between the PGA, PGV, PGD and Intensity. The result show of the vulnerable zones is located around Donggala district near from the epicentre of the largest earthquake, which was M7.5 on September 28, 2018. Besides that, empirical formulation obtained with a linear regression approach is used for the sustainability of this methods.
