Landslide susceptibility is classified as high in Thailand. This indicates that because of the rainfall patterns, terrain slopes, geology, soil, land cover, and (potentially) earthquakes in this area, localized landslides are a common dangerous event.
Based on this information, planning choices such as project siting, design, and construction methods must include the possibility of landslides. The landslide danger is one of Thailand's main natural disasters, causing massive loss of life and property. When catastrophic flooding and landslides occurred in Kathun district, Nakhon Sithammarat Province, southern Thailand in 1988, public awareness increased substantially, with approximately 230 casualties in Ban Kathun Nua.
