How to assess landslide activity and intensity with Persistent Scatterer Interferometry (PSI): the PSI-based matrix approach

Abstract: We provide a step-by-step analysis and discussion of the 'PSI-based matrix approach', a methodology employing ground deformation velocities derived through Persistent Scatterer Interferometry (PSI) for the assessment of the state of activity and intensity of extremely to very slow landslides. Two matrices based on PSI data are designed respectively for landslides already mapped in preexisting inventories and for newly identified phenomena. Conversely, a unique intensity scale is proposed indiscriminately for b… Show more

“…In order to compare more specifically InSAR results with local failures and building damages, PSI data measured along the satellite LOS were projected downslope along the maximum steepest slope, following the approach presented and applied in previous works by the scientific community (COLE- SANTI and WASOWSKI 2006;CASCINI et al 2009;CIGNA et al 2012CIGNA et al , 2013GRIEF and VLCKO, 2012;BIANCHINI et al 2013;HERRERA et al 2013).…”

“…The so-called V SLOPE values obtained through the projection of LOS displacement values (V LOS ) allow a more intelligible interpretation of radar data with respect to the local morphology (CIGNA et al 2013;BIANCHINI et al 2013). Several limitations need to be accounted for when projecting the velocity along the slope.…”
