Application of the multichannel surface wave analysis (MASW) method for site characterization: case study of infrastructure assessment in North Morowali Regency

Abstract

Abstract Studies regarding site characterization are critical to determine the feasibility and model of infrastructure that can be built in an area. One method that is very reliable in site characterization is Multichannel Analysis of Surface Waves (MASW). This method utilizes surface wave (S-wave) propagation to identify the subsurface. Therefore, in this research, an infrastructure assessment was carried out in the North Morowali Regency area using the MASW method. Based on the results of the shear wave velocity profile (Vs), the research area is dominated by clay to dense sand. Therefore, it is highly recommended that the infrastructure model built in the North Morowali area be adapted to the conditions of the sites that dominate the area so that the buildings to be built will last a long time.
