Kinematics of slow-moving active landslides

focus-Modellazione num_sezioni Portalet-evidenza-2 We experiment the application of 3D numerical modelling techniques for the analysis of the kinematics of slow-moving active landslides. The activity assesses the hazards posed by slow-moving landslides, determines the factors controlling the slope processes, investigates the potential evolution of the active slopes, and helps selecting appropriate slope mitigation strategies. We exploit modern numerical modelling techniques based on finite ...

Radar remote sensing techniques for the detection and measurements of ground surface deformations

DInSAR-in_evidenza- Space-borne radar interferometry or DInSAR (Differential Interferometric Synthetic Aperture Radar) is one of the latest techniques used for the detection and measurement of ground surface deformations caused by natural and / or man-made events. The DInSAR technique has been successfully used in the measurement of seismic deformations and of the effects of subsidence, unstable slopes and inflation of magma in volcanoes. The growth of space ...

Threedimensional Displacement Analysis

prodotti-servizi-3da-evidenza The 3DA software is a new procedure that allows retrieving in near-real-time 3D surface deformation models starting from data acquired via robotized total stations or others system that acquire the surface displacements. The measurements are first pre-processed and then implemented on 3D maps that include vector arrows representative of the intensities and of the real directions of motion in a given system of coordinates. The 3D surface ...

Sinkholes in the Marina di Lesina area

Lesina_gabbionate- Sinkholes are in Apulia among the main geohazards, and are at the origin of severe interactions with the anthropogenic environment, and heavy losses to society. Since several years the territory of Marina di Lesina is diffusely affected by development of sinkholes (that have caused an emergency state to be declared), mostly concentrated near the Acquarotta Channel, linking the Lesina Lake to the Adriatic ...

DInSAR techniques for the assessment of sinkhole hazard

OLYMPUS DIGITAL CAMERA Sinkholes occur as sudden collapses of the ground, related to natural cavities produced by karst processes in soluble rocks, or to man-made cavities deriving from different types of human activities in different historical ages. Sinkholes are widespread all over the world, and the related hazard is extremely high, with very severe damage to built-up areas and human infrastructures, and heavy losses to the ...

Investigation of postglacial fault zones using DInSAR

svezia-evidence-ev Fennoscandia bears witness of the Pleistocene glaciation in the form of a series of large geological faults. Pärvie which is the longest runs for 150 km. No information is available on its state of activity and no surface deformations data have ever been collected. The length of the fault and its location, make the traditional monitoring techniques unfeasible and ...
