    Description: We present results of a multi-temporal analysis of airborne LiDAR data collected between 2006 and 2010 on the 3 km long active Montaguto landslide (Italy). Digital Terrain Models are constructed from data acquired on May 2006, July 2009, April 2010 and June 2010. The spatial distribution of selected morphometric parameters and the statistical analysis of the temporal variations of such parameters allow us to reconstruct the evolution of the landslide. We recognize zones of uplift and subsidence, estimate the volumes of removed or accumulated material, and determine the average rate of vertical and horizontal displacement. We also map the deformations structures and provide new insights on the sliding mechanisms. Zones in which the topographic features change due to handling/removal work are also analyzed. The approach proposed here provides new insight on the use of airborne LiDAR in the surveillance strategies of landslides and other gravity-controlled processes.

    Description: Tecniche di monitoraggio Lidar multi temporale sono state sperimentate dalla Nuova Avioriprese S.r.l., azienda del Consorzio AeroSigma S.c.a.r.l., in stretta collaborazione con il Laboratorio di Geomatica e Cartografia (LGC) dell’Osservatorio Vesuviano, Sez. di Napoli dell’Istituto Nazionale di Geofisica e Vulcanologia – INGV, al fine di definire una procedura di monitoraggio delle frane attive basata su dati da Telerilevamento aereo di tipo ottico, termico e Lidar. La frana di Montaguto (AV), attualmente la frana attiva più lunga d’Europa (3.800 Km) che ha recentemente coinvolto importanti infrastrutture di collegamento tra Puglia e Campania con gravi danni economici e sociali, ha rappresentato il caso reale di applicazione della metodologia di monitoraggio aereo. Questo movimento gravitativo del suolo, la cui dinamica ed evoluzione risulta ascrivibile, con le dovute differenze di temperatura e viscosità ad una colata lavica incanalata, è iniziato nel 2004 su terreni agricoli fino ad invadere, nel 2006, il fondovalle del Fiume Cervaro; nel 2010 la frana ha raggiunto la SS 90 e successivamente la linea ferroviaria Caserta Foggia, interrompendo per mesi i collegamenti su uno dei principali assi di trasporto del Meridione. La complessità e l’estensione del fenomeno attivo, la sua velocità di movimento e deformazione, unitamente alle condizioni di elevata esposizione al rischio delle infrastrutture di trasporto presenti, richiedono il supporto di strumenti in grado di poter percepire in modo areale gli spostamenti e le modificazioni in atto con l’obiettivo di prevederne l’evoluzione in termini di dinamica, estensione e volumi potenzialmente interessati Le informazioni estratte dai dati Lidar multi temporali, integrate da dati ottici aerei e da dati cartografici hanno consentito la produzione di utili parametri di studio e monitoraggio del fenomeno franoso, verificando le condizioni di evoluzione dei fenomeno nel tempo e monitorando gli effetti degli interventi di messa in sicurezza e di mitigazione degli eventuali rischi di riattivazione del fenomeno.

    Description: A multi-temporal LiDAR study of an active landslide at Montaguto (Italy) is presented. Four LiDAR-derived Digital Terrain Models acquired on May 2006, July 2009, April 2010 and June 2010 are used. The interpretation of selected morphometric parameters (surface roughness, residual topographic surface) and the statistical analysis of the temporal variations of such parameters allowed the reconstruction and tracking of the landslide. The landslide boundary monitoring was achieved and zones of uplift and subsidence, volumes of removed and/or accumulated material, and average rates of vertical and horizontal displacement (retreat rate of the crown and advancement rate of the toe) were estimated. Deformation structures (scarps, cracks, folds) affecting the landslide in different times were also mapped; some of such structures represent precursors of impending instability processes or give information on the mechanism of emplacement. Various types of activity (e.g. rock-fall, flow) and geometry (e.g., channelized flow) are recognized and zones whose topographic features change with time due to artificial drainage and earth handling/removal work were detected. The LiDAR-derived information allows us to decipher the kinematics of the landslide. The results provide new insight on the use of airborne LiDAR in the monitoring strategies of gravity-controlled processes.
