Abstract

The use of the GIS method in mapping zones of potential landslides usually involves subjective criteria which produce inaccurate results if the criteria are not proper. This paper discusses the use of a Landslide Hazard Evaluation Factor (LHEF) in mapping zones of landslide potential for a large area. The technique contains standardized factors and landslide classification that will aid researcher to map landslide potential of an area in accordance to the standard. Six landslide factors were used in this research to map the landslide hazard potential zone along km 160-km 190 of the East Coast Highway (ECE), Pahang. The landslide susceptibility factors used in this research are lithology, soil type, landuse, topography, slope steepness and annual rainfall. The landslide hazard potential map of the study area were produced and classified to four potential zones with the highest area percentage namely high potential (38. 9%), very high potential (13.4%), moderate (37.0%) and low potential (10.7%). Factors that caused instability of the study area are lithology such as shale, siltstone, phyllite and slate as well as soil type containing high percentage of clay. Rainfalls factor are considered as the triggering factor of instability of the study area. The accuracy was assessed using correlation coefficient method, the landslide hazard potential map is compared to the landslide distribution of the study area, which gives a correlation coefficient of 0.87. This value indicates that the landslide hazard potential map according to the Landslide Hazard Evaluation Factor technique can yield high accuracy landslide hazard potential map.
