“…For analysing the evolution of landslides, historical aerial images were already used, but without adopting the SfM approach (e.g. Casson et al 2003;Guerriero et al 2013). In this work, several previous applied approaches were merged to investigate as longest period as possible of the CL-PO This paper presents the multitemporal analysis applied to six sets of historical photographs from 1945 to 2003, which enabled the recognition of the geomorphological evolution of the CL-PO landslide over approximately 60 years.…”

Multisource data integration to investigate one century of evolution for the Agnone landslide (Molise, southern Italy)

Landslides are one of the most relevant geohazards worldwide, causing direct and indirect costs and fatalities. Italy is one of the countries most affected by mass movements, and the Molise region, southern Italy, is known to be susceptible to erosional processes and landslides. In January 2003, a landslide in the municipality of Agnone, in the Colle Lapponi-Piano Ovetta (CL-PO) territory, occurred causing substantial damage to both structures and civil infrastructure. To investigate the evolution of the landslide-affected catchment over approximately one century, different data were taken into account: (i) literature information at the beginning of the twentieth century; (ii) historical sets of aerial optical photographs to analyse the geomorphological evolution from 1945 to 2003; (iii) SAR (Synthetic Aperture Radar) data from the ERS1/2, ENVISAT and COSMO-SkyMed satellites to monitor the displacement from 1992 to 2015; (iv) traditional measurements carried out through geological and geomorphological surveys, inclinometers and GPS campaigns to characterize the geological setting of the area; and (v) recent optical photographs of the catchment area to determine the enlargement of the landslide. Using the structure from motion technique, a 3D reconstruction of each set of historical aerial photographs was made to investigate the geomorphological evolution and to trace the boundary of the mass movements. As a result, the combination of multitemporal and multitechnique analysis of the evolution of the CL-PO landslide enabled an assessment of the landslide expansion, which resulted in a maximum length of up to approximately 1500 m. A complete investigation of the past and present deformational sequences of the area was performed to potentially plan further mitigation and prevention strategies to avoid possible reactivations.

“…1). The total flow volume is approximately 0.004-0.006 km 3 Guerriero et al, 2013;Lollino et al, 2014); the landslide covers an area of 0.66 km 2 and the average travel angle (or shadow angle, defined as the slope of a line joining the tip of the debris to the landslide crest of the main scarp) is 8.4 • .…”

“…The landslide material is supposed to be mainly formed of restructured and remolded soils originally belonging to the Faeto Flysch Formation (Lollino et al, 2014), whereas the Villamaina Unit presumably represents the substratum over which the landslide mass has moved (Guadagno et al, 2005;Guerriero et al, 2013).…”

Abstract. On 10 March 2010, because of the heavy rainfall in the preceding days, the Montaguto landslide (Southern Italy) reactivated, affecting both state road 90 "Delle Puglie" and the Rome-Bari railway. A similar event occurred on May 2005 and on September 2009. As a result, the National Civil Protection Department (DPC) started an accurate monitoring and analysis program. A monitoring project using the GB-InSAR (ground-based interferometric synthetic aperture radar) system was emplaced to investigate the landslide kinematics, plan urgent safety measures for risk mitigation and design long-term stabilization work.Here, we present the GB-InSAR monitoring system results and its applications in the observational method (OM) approach. GB-InSAR is an established instrument for longterm campaigns aimed at early warning and monitoring during construction works. Our paper further develops these aspects in that it highlights how the OM based on the GBInSAR technique can produce savings in terms of cost and time in engineering projects without compromising safety. This study focuses on the key role played by the monitoring activities during the design and planning activities, with special reference to the emergency phase.

“…Such a high number has to be attributed to the geological and geomorphological context of the Italian territory, but also to an incorrect land management, started during the economic miracle in the early 60's. In particular, landslides characterized by slow to moderate kinematic are largely common in Central and Southern Italy: some of the most recent cases which can be mentioned are Agnone [7][8], Montaguto [9], Moio della Civitella [8-10-11]. These slope movements are characteristic, with a long evolutionary history, and with several reactivations of the already deformed mass, due to extraordinary rain or seismic events, and at times due to the human action.…”

The Differential SAR Interferometry (DInSAR) is one of the most powerful devices for monitoring deformation processes on the Earth surface. Here, a dataset of TerraSAR-X StripMap imagery covering almost the whole Crotone province territory, located in the south of the Italian peninsula, has been selected and processed. The time span goes from April 2008 to June 2010. In this work, two different multitemporal interferometry (MTI) approaches and two different software packages have been used and compared in order to identify benefits/constraints of each MTI approach and each software. Such approaches are: the 'permanent' (or 'persistent', or 'point-like') scatterers [1] implemented on the SARscape® software [2], and the Temporal Sublook Spectral Coherence (TSSC), derived from Coherent Pixel Technique algorithm and works on SUBSOFT processor, developed by the Remote Sensing Laboratory (RSLab) group, from the Universitat Politècnica de Catalunya (UPC) [3][4][5].
