Geology and landslide hazard zonation by using gis at Kampung Kundur, Gua Musang, Kelantan

The research area is located at Kampung Kundur, Gua Musang, Kelantan. This study area are covered about 25km2.It is bounded by longitude line 101o54o00” E to 101o56o35” E and latitude line 4o55o90 N to 4o52o45” N. These research study was conducted to update the geological map of Gua Musang with the scale of 1:25000, to analyze the factor in the research area that is causing the landslide incidence and to generate landslide hazard zonation map of study area, Gua Musang with the scale 1:25000. These research study was carried out only using secondary data from online resource such as U.S Geological Survey Earth Explorer (USGS), ArcGIS and Jabatan Pengairan dan Saliran (JPS). The geological aspect that involve in this research study are study of geomorphology, stratigraphy, structural geology, and historical geology. From the landform analysis of the study area, consists of low hills area and hills area from 90 m - 290 m. The method used in generating the landslide hazard zonation map is using Geological Information System (GIS) which is using Weighted Overlay Method (WOM). In this research, five difference parameters generated and overlay based on the its importance in order to determine the tendency of landslides occurring in the study area. These factors are land use, slope, aspect slope, geomorphology and geology. The results showed that the landslide hazard zonation was divided to five classes of zonation. Class 5 is the highest hazard and most potential hazard, class 4 is a high hazard, class 3 is medium hazard, class 2 is low hazard and class 1 is no hazard. The resulting landslide susceptibility map identified five zones of susceptibility of landslide hazards, from very high hazard zone (4.7 %), high hazard zone (33.8%), moderate hazard zone (40.5 %), low hazard zone (18.4 %), and very low hazard zone (2.6 %). The outcome was confirmed by relating with the landslide occurrences in different classes
