Geology and landslide hazard zonation using geographic information system (GIS) in Chucuh Puteri, Kuala Krai, Kelantan

This research entitled geology and landslide hazard zonation using Geographic Information System (GIS) in Chucuh Puteri, Kuala Krai, Kelantan. The study area isis about 25 km2 which aligned along latitude 5°21'3.90"N to 5°21'2.73"N and longitude from 102°17'21.23"E to 102°17'21.02"E. The aim of this research is to generate geological map of Kampung Chucuh Puteri, Kuala Krai, Kelantan with scale 1: 25 000, to identify the causative parameters that may be triggering a landslide and to produce a Landslide Hazard Zonation (LHZ) map of Kampung Chucuh Puteri, Kuala Krai, Kelantan. The current project's geological mapping is based on fieldwork, which includes taking samples from recently formed outcrops and examining drainage patterns, geomorphological features, and other factors. Granite, granodiorite and quartzite are among the lithological founds at the research area. In order to generate the landslide hazard zonation map, an integrated approach of WOM using GIS technology was applied using several parameters. The parameters were extracted using Digital Elevation Model (DEM) data. An overlay and raster calculation in GIS was used to generate results of landslide hazard map of Kuala Krai. The map which has different classes which was class 1 represents no hazard, class 2 represents a moderate hazard, class 3 represents a medium hazard, class 4 represents a high hazard, and class 5 represents the highest hazard. The factors that caused the landslide were recognised as heavy rainfall intensity. As a conclusion, the ability to identify landslides will provide society with a better knowledge and understanding of landslide mechanisms, as well as a better prevention of the most likely failure area that has high prone landslide for future planning.
