Abstract
The location of Bulukumba Regency, which is traversed by the Walanae Fault, indicates that this area has the potential for earthquakes. The potential for this earthquake is also reinforced by the condition of the Bulukumba Regency landform, which is composed of landforms of volcanic and tectonic origin. The purpose of this study was to analyze the hazard potential of the earthquake through the peak ground acceleration approach and to analyze the relationship between the landform and the peak ground acceleration value in Bulukumba Regency. The methods used in this study are statistical methods, descriptive qualitative, and spatial analysis. The results of this study indicate that the value of peak ground acceleration (PGA) in Bulukumba Regency based on the earthquake historical report for the period 1921-2023 is 67-121 gal. The PGA value, at 67-88 gal with low hazard criteria, is a site on the land from the volcanic process. The PGA value, at 89-121 gal with low hazard criteria, is a site on the land from structural and fluvial processes. Output of this research be expected can become input for the revision of spatial plan in Bulukumba Regency.
