Analytical landslides prone area by using Sentinel-2 Satellite Imagery and geological data in Google Earth Engine (a case study of Cinomati Street, Bantul Regency, Daerah Istimewa Yogyakarta Province, Indonesia)

Abstract

The incidence of landslides and the fact that a large number of people live in areas vulnerable to landslides lead to a high death toll in Java Island, Indonesia – more than 1,112 people in the period 1999 to 2005. The study site has an area of 55.56 hectares, along Cinomati Street, Dlingo, and Pleret Sub District, Bantul District, Daerah Istimewa Yogyakarta Province, Indonesia. The methods that use in this study are, Sentinel-2 Imagenery and Geological data. The purpose of this study is to determine the landslides prone area in the study site. The methods used in this study are Sentinel-2 Satellite Imagery and geological data. Along the Cinomati road based on geological data, it has a weak area that has the potential for landslides from the continuation of the Opak fault and rock formation boundaries. Landslide area are locations with complex geological conditions and sparse vegetation. In other rare vegetation besides the location of landslides, it also needs to be aware of other potential landslides, because this research is limited to sentinel images with a density of 10m2.
