Abstract
Over the years, due to the torrential rainfalls and vast development of hilly areas, landslides have been a pressing issue affecting the community. This study explores the awareness of the Malaysian community towards the disaster (landslides), identifies the developments (policies and action taken) in some selected countries' landslide disaster policies and compares it to Malaysia’s and finally, the development of a risk management index. The first questionnaire was designed according to the disaster management cycle, whereby the public was asked for their opinion on disaster risk management in Malaysia. For the questionnaire involving the public, 190 respondents were involved. The second questionnaire aimed at experts in the industry was devised to measure the performance level of indicators. This survey involved 43 experts from the local authority in various localities throughout Malaysia, including east Malaysia. On top of this, a third survey was done, which involved seven top experts (in the geotechnical area) in Malaysia who participated in a pairwise study using the Analytical Hierarchical Process (AHP) method. The pairwise comparison matrix calculates the Risk Management Index (RMI). The result infers that the public in Malaysia is aware/ alert to the occurrences of landslides with little technical and general knowledge. Regarding disaster policy and practices, Malaysia is on par with its Southeast Asian counterparts, this can be reflected based on the extensive literature review done in the study. Lastly, Malaysia garnered a Risk Management Index (RMI) score of 60.31, similar to Hong Kong and Norway, which has also adopted the calculation method.
