Description
Summary:Central Sulawesi has the Palu Koro fault at any time it can cause an earthquake. One of the impacts caused by this earthquake is liquefaction. The purpose of the study was to identify the subsurface layer of the soil that is suspected to be one of the Central Sulawesi has the Palu Koro fault at any time it can cause an earthquake. The purpose of the study was to identify the subsurface layer of the soil that is suspected to be one of the causes of liquefaction in the Sigi Biromaru district in Jono Oge village and Lolu village. The stages of this research method are to determine the subsurface layer using the geoelectric method of the Schlumberger configuration and the Wenner-Schlumberger configuration. The results showed that both locations had the first layer consisting of clay, sand, and silt. The second layer consists of sand, sand, gravel. In contrast, the third layer consists of clay, which is quite thick at a depth of 10-15 m below the soil surface, forming a continuous layer with a thickness of 7-12 m that does not pass water so that the layer above it or the second layer is categorized as a water-saturated layer.
