Abstract

Subdistrict Galesong is lying areas and coastal areas with an altitude of 0-100 meters above sea level. This spurred the use of land for the functional area awakened. Based on this case, it is necessary to conduct research on seismic vulnerability distribution in Kecamatan Galesong of Takalar Regency. Primary data are taken directly around the north coast Galesong using 303S TDL. The data taken as much as 5 points of measurement with the distance of each point about 500 meters. Further data measurement is then processed with Geopsy software. The frequency value is 0,416-0,509 Hz hence the dominant alluvial rock study location, where at point MG02 is the most vulnerable area with value 105,9918. While based on the value of PGA is 8.4-9.4 Gal, then the location of research including very small level of risk of earthquake.
