Abstract

[automatically translated] Exploiting Google EarthTM to assess susceptibility to landslide model: a test in central Sicily. A landslide susceptibility multivariate model, based on the conditional analysis approach, Has Been Tumarrano derived in the river basin (about 78 km2), by intersecting grid in GIS layers, expressing some selected geo-environmental conditions (lithology outcropping, steepness, plan curvature and topographic wetness index), and a landslide vector archive, produced by Google EarthTM aided remote survey. The analysis of the images Google EarthTM dated at 2006, allowed to Recognize 733 landslides (30 rotational slides and flows 703), almost Exclusively Affecting clay and sandy clay rocks. Validation procedures produced largely satisfactory results, Which Were Analyzed in the domain of the success and prediction rate curves.
