Landslide Prone Maps Using Weighting Parameters in Pulung, Ponorogo East Java

Abstract

Abstract Pulung landslide occurred twice during 2017-2018. The landslide located in the village of Banaran and Wagirkidul, which caused losses. This study aimed to identify the susceptibility level of the landslide in areas of Pulung. This research using four parameters, namely land slope, land use, soil type, and rainfall. This study produces landslide prone maps divided into three levels. It is the level of “very vulnerable” covered area of 3.4% (433.67 ha), level of “vulnerable” covered area of 53.06% (6,767.803 ha), and level of “less vulnerable” covered area of 43.54% (5,553.527 ha). The results are useful for an early warning system in Pulung, especially rainy season. The map presented is also considered as the source for warning landslide system in surrounding Pulung.
