Main Article Content
Landslides are very frequent and disastrous phenomena in the Western Ghats regions of South East Asia during the monsoon season and it occurrence is triggered by many factors. Hence, it is essential to develop a landslide hazard assessment map to find out the areas at risk, so that potential disasters can be reduced. The present study clearly aims to delineate the landslide susceptibility zones so that landslide hazard and risk can be properly managed. The landslides occurred in Amboori region, the southeastern part of the Thiruvananthapuram district, Kerala, India has been analyzed using GIS and remote sensing techniques to identify the landslide susceptibility zones. Frequency Ratio analysis is made use of in this study. The landslide hazard zonation has been done based on various terrain parameters as well as various thematic layers that affect directly or indirectly slope failure process. The results of landslide analysis not only helps to map and monitor landslides, but also to predict future slope failures which is valuable for a decision maker in landslide prone areas.
