This coastal hazard causes significant risk like physical damage. Accordingly, disaster risk reduction program in coastal areas is indispensable in advance for the next destructive coastal hazard event. This need is answered by conducting disaster risk analysis as the first step in coastal erosion identification in the Mentawai Islands. The risk was obtained using a qualitative approach by combining the multidimensional aspects of hazard as well as vulnerability. Hazards aspect was derived from identification of physical variables to erosion and was represented by index value. Vulnerability aspects consist of physical aspect and social aspect. The physical aspect is the distribution of buildings and the social aspect is population density that obtained by modeling process. The result indicated that the eastern Mentawai coast has a wider area of erosion risk than the west coast due to the influence of the Australian monsoon.[/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]Coastal erosion,Disaster risk reductions,Mentawai,Modeling process,Physical aspects,Physical variables,Population densities,Qualitative approach[/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]Coastal Erosion,Disaster Risk,Mentawai[/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/10.1109/AGERS.2018.8554203[/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]
