Typical road-induced landslides: fillslope failure (FSF) and cutslope failure (CSF) are their main interpretation keys of remote sensing. Both main scarps of FSF and CSF are relatively obvious border and brighter than surrounding colour. From image texture, we can see the traces and stacks caused by movement of the displaced material and surface erosion. The vegetation coverage is relative low. The CSF with excavation signs always locate above and adjacent roads with steep slope, and the FSF always locate under and adjacent roads with relative big slope. The image was provided by DigitalGlobe and obtained from Google Earth 7.1.
