Landslide assessment using interferometric synthetic aperture radar in Pacitan, East Java

<span>Landslides are a common type of disaster in Indonesia, especially steep-slope areas. The landslide process can be well understood by measuring the surface deformation. Currently, there no practical solutions for deformation at locations other than field surveys Pacitan Regency. We apply LiCSBAS, to identify several specific non-urban area with mixed topographical features. LiCSBAS is module that utilizes data from project looking inside continent space (LiCS), using new small baseline subset (NSBAS) method. This study leaf index (LAI) validate ability detect values locations. succeeded identifying deformations 100 locations, ranging 15.1 10.9 millimeters per year. Most closely related volcanic rocks and sediments on slopes 30–35°. NSBAS method reduce gaps error sentinel-1 image network. However, utilization C-band pixel size meters made only detectable large open area.</span>
