LANDSLIDE HAZARD ZONATION FOR PAYA TERUBUNG - RELAU SLOPE TERRAINS IN PENANG ISLAND

摘要

Lately there are many landslide disaster cases which have been reported and most of the occurrences are due to human factors such as extensive earth cutting, land clearing, agricultural activities, burning, uphill developments and other due causes. A study of Paya Terubung-Relau slope terrains which situated in between two hill ranges of Bukit Penara and Bukit Kukus at almost in the middle part of the Penang Island was selected as the study area. The place was selected due to its highest records of landslide occurrences in the Island and also the vast hill development area. Geographic Information System (GIS) method was applied where the data obtained been digitized, attributed, layered and interpolated in the process of obtaining the hazard zonation maps. Then these Information where then used to interpreted in obtained hazard risk assessment maps. The maps will be of beneficial where geotechnical and GIS inputs were incorporated in the landslide analysis to the study area for the risk assessment.
