The Bogowonto estuary project in Indonesia constructs an embankment with an average height of 4 m. The subgrade is characterized by a high ground water table and loose sand characteristics that make the area very susceptible to earthquake-induced liquefaction. The disastrous effects of liquefaction on embankment constructions include extreme settlements, lateral spreading, and slope instability. Therefore, evaluating the probability of liquefaction and estimating lateral spreading is essential in the preliminary phase of a mitigation plan. Furthermore, the critical point for technical data in soil liquefaction is to generate results with site-specific response analysis (SSRA). Consequently, this research aims to generate the liquefaction susceptibility assessment and initial lateral spreading estimation based on the site-specific ground response analysis. The DEEPSOIL V.7 is applied to conduct peak ground acceleration in each layer compared to the maximum acceleration from the Indonesia Hazard Map. The empirical equation was utilized to produce the SF value and the lateral spreading parameter; volume strain, and shear strain. The results represent the strong connection between each parameter: SPT correction, SF, volume strain, and shear strain. The input of the SSRA presents the differences between the SF results. Further analysis is expected to be conducted for a more comprehensive output.
