This may be caused by Lembang Fault. Lembang Fault has peat formation and big gradient around 450, high rainfall rate at rain season, and has possibility for earthquake to occur. At some places in Langensari sub district, there are only slight vegetation which worsen the situation. The aim of this study is to map the places which have potential for earthquake to occur. The subject that studied is the structure and the content of the soil layer and rocks within the fault and water content that have potential to cause landslide. To know the content of the rocks and water resistivity is used. The method that used including some steps those are geological and geophysical based. Those steps are field survey geologically, resistivity data acquisition using dipole-dipole array, processing with RES2DINV and interpretation to get landslide model resistivity. From the model it can be concluded that there is high resistivity contrast. This contrast indicates that there is a surface of rocks that has potential to cause landslide. This body of rocks has 8 meters thickness. The body of rock under the landslide surface has high porosity that causes water to be stored in large capacity.[/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/10.1063/1.4990924[/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]
