Landslides in the Solar System

Focus3- On Earth, landslides are hazardous phenomena often associated with economic damage and loss of human lives. The most common natural triggers of terrestrial landslides are intense or prolonged rainfall, earthquakes, rapid snow melting, and volcanic activity. But what are the main natural triggers of landslides on other solid bodies of the Solar System?Since the early 70’s of the last century, landslides were observed on the surface of the ...

Kinematics of slow-moving active landslides

focus-Modellazione num_sezioni Portalet-evidenza 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 ...

Forecasting rainfall-induced landslides

focus-sake-evidenza We developed GASAKe, Genetic Algorithm-based Self-Adaptive Kernel, a new model to predict the time of occurrence of rainfall induced landslides.GASAKe predicts the time of occurrence of single landslides or groups of similar landslides, both shallow and deep-seated, using a threshold than when exceeded determines the initiation of the landslides. The triggering threshold is defined using historical information on rainfall and ...

Geohazard impact assessment for urban areas

progetto-safety-evidenza- The project is focused on monitoring geohazard-associated ground deformations, a key prevention action specifically addressed to urban areas and critical infrastructures. The project will propose a procedure to produce maps to assess continuously the potential impact of geohazard activity. These maps will provide inputs to support early warning, giving information on the stability of the monitored areas and to evaluate the expected ...

Earthquake-induced landslides

focus-frane-sismoindotte-wasowski-evidenza Landslides and earthquakes are important geological hazards in Italy, where mountains and hills dominate a landscape characterized by the presence of weak geological materials. The geological and morphological settings result in high susceptibility to landslides under seismic conditions. Italy is also one of the most active tectonic regions in Europe; and seismic shaking is known to have caused landslides in Italy.Numerous historical ...

Where we should not expect landslides?

nonsusc_valcmonica_20150726_3D_IN_EVIDENZA-3 Landslide susceptibility is the propensity of a territory to generate landslides.Many methods are available to determine landslide susceptibility, whereas only a few attempts were made to outline areas not likely to generate landslides i.e., non-susceptible landslide areas. This is surprising, because for planning purposes it is just as important (if not more important) to know where landslides are not expected than to know where landslides ...

Joint modeling of landslides and erosion processes

LANDPLANER_Copertina_20150721- Different approaches have been proposed to model landslide and erosion processes separately. Only a few attempts have been made to model landslide and erosion jointly. Some models consider the effects of landslides on sediment yield and transport. In other cases, landslides and erosion processes are components of a landscape evolution model. However, existing models do not describe jointly the triggering mechanisms of landslide and erosion ...

Landslide susceptibility models and maps

LAMPRE leaflet Landslide susceptibility is the likelihood of a landslide occurring in an area, given the local terrain conditions. It is the degree to which an area can be affected by future landslides i.e., an estimate of “where” landslides are more likely to occur.Landslide susceptibility does not consider the temporal occurrence or the magnitude of the expected landslides. In mathematical language, landslide susceptibility can be expressed as the ...

Rheology of geological processes

evidenza-roger Critical and depositional friction angles are characteristic for the deposition of a granular mass; the wrong angle adoption determines the ineffectiveness of a containment basin. The term is used with different meanings and measured by various procedures. The numerical simulation is a useful tool for the hazard assessment, but the definition of friction needed parameters requires insights on their ...

Damaging geo-hydrological events in Calabria from 1990 to 1999

focus-calabria-2-evidenza We published a book entitled “Eventi alluvionali in Calabria nel periodo 1990-1999” (Alluvial events in Calabria from 1990 to 1999)Link to the Book» The volume is the result of a study that lasted more than a year, and was part of long-lasting research effort to investigate historical landslide and flood events in Calabria, which started in the ‘70s of last century.To search the information, we went to the Public Provincial ...
