HISTORICAL ANALYSIS OF LANDSLIDES EVENTS IN MALAYSIA: IMPACT ON PHYSICAL AND SOCIO-ECONOMIC

Any earthly substance, including rock, soil, artificial fill, or debris, moving in large quantities down a slope is called a landslide. They may occur quickly or gradually over an extended length of time. A landslide occurs when the force of gravity exerted on a slope surpasses the forces that prevent it from failing. Malaysia is a tropical nation that receives a lot of rainfall and rich residual soil. Numerous landslide incidents that happened during Malaysia's rainy season are publicized in the media, and some landslides repeat themselves in the same spot over time. The aim of this research is to examine the past landslide incidents that occurred in Malaysia from 1961 to 2023 and their effects on the country's physical and socioeconomic circumstances. Data on past landslides were gathered from local news sources, earlier studies, and reports from local government agencies. There have been a significant number of fatalities, property damage, and both direct and indirect economic ramifications from the landslide tragedy. To reduce adverse environmental effects, it is advised that any development on high land areas be subject to additional restrictions. Additionally, during the planning and management phase, the public should be made aware of the risks associated with landslides. When designing, analyzing, and planning a development in a hilly area, susceptibility evaluations may also offer significant insights.
