One of the mitigative approaches into investigating landslide is to identify a potential slip zone usingresistivity method. In this study, the array chosen to acquire the resistivity data was Wenner array as it provides a robust resolution in mapping lateral resistivity variations. This method will generate a contour map portraying thedistribution of resistivity values of the subsurface. Beforehand, a 2-dimensional forward modeling was conducted to acquire anexpected ideal result of possible potential slip zone. Landslides itself are affiliated with a low resistivity zone that is locatedbetween two high resistivity zones. This study is conducted in a ground slump in Jalan Citra Green, Northern Bandung which is comprised of mostly unconsolidated soil. By applying a least-square inversion to the resistivity data obtained, resistivity values of 10-200 Ωm is attained. Based on the inversion result, a low resistivity zone of 10-20 Ωm is identified spanning from the surface to approximately 10 meters deep. In conclusion, furtherinvestigations are needed to determine whether the low resistivity zone is associated with potential slip zone as our datais limited to a single line.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.4990933[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
