Monitoraggio del Rischio da Frane con tecnologie EO
Le frane sono eventi del tutto naturali nell’evoluzione di un territorio, in particolare in Italia. Esse pongono un problema e diventano un pericolo allorché interagiscono con l’uomo e l’ambiente antropico. I movimenti franosi presentano una grande varietà fenomenologia. Le notevoli differenze nella tipologia, dimensione, e velocità di spostamento delle frane, rendono difficile e complessa la definizione della loro pericolosità, per ...

The 3 December 2013 Montescaglioso landslide
SANF Liguria
In Italy, landslides are triggered by intense and/or prolonged rainfall. The spatial and temporal forecast of multiple landslides triggered by rainfall in wide areas relies primarily on empirical rainfall thresholds. It is widely believed that the thresholds are influenced by the local topographic (morphological), lithological, soil, and climatic settings. For this reason, it is necessary to define local rainfall thresholds. Reliable local ...
Landslide maps for the Castelfranci municipality
Castelfranci (Avellino, Campania) is located in the catchment of the Calore River, in correspondence of a N-S oriented stretch of the river. This territory is intensely affected by landslide development, which more than once was in the past at the origin of severe damage to the local community, and heavy losses to ...
SAR change detection methodologies for event landslide mapping
The project explores and implements multi-scale and multi-sensor SAR change detection methodologies for event landslide mapping. Automated analysis for change detection is a challenging task due
to the inherent noisiness of SAR imagery and also to the high sensitivity to texture variability due to different acquisition angles. Moreover, pre-processing (de-speckling) may lead to the degradation
of the geometrical details and affect the ...
Alarm and monitoring systems for debris and mud flows
Monitoring of debris flows in instrumented areas is carried out since many years in different Countries worldwide. It is still missing, however, an adequate standardization of methodologies, instrumentations and procedures. The instrumented areas are also employed for testing warning systems. Even though these latter have been more and more employed, a systematic experimentation of these systems has not yet been carried ...
Geo-hydrological hazards in the Pogliaschina catchment
The occurrence of flash floods in mountainous catchments is often associated to relevant geomorphic effects, both in the channel network (channel changes and transport of large wood), and on the hillslopes (landslides and soil erosion). The concomitance of flash floods, channel changes and landslides enhances hazards and risk associated to individual ...

Time-Space prediction of high impact landslides under changing precipitation regimes
In Italy a significant increase of landslide frequency and intensity in the last decades has been occurred, whose impact must be evaluated with respect to the convergence in possible negative effects of both rainfall regime changes and of urban development as well as land use changes. Italy, due to its geomorphological and urbanization characters, represents today large areas where landslide risk is at the highest ...
Rainfall, seismicity, landslides and sediment discharge in mountain belts
Taiwan, an active orogenic belt with subtropical climate is characterized by a high uplift rate and several major typhoons each year. Italy is on one of the most seismically active regions in Europe because of the thrust of African plate on Eurasian continental one. Both experience numerous landslides along with earthquakes and intense rainfalls, causing heavy damages and casualties. The purpose of this project was to share scientific knowledge ...
Management of sediment transport in small mountain catchments
Sediment transport in small mountain catchments (drainage area < 10-20 km2) is a fundamental process for the equilibrium and the dynamics of the whole channel network. At the same time, sediment transport can create high-risk conditions due to the occurrence of extreme phenomena such as debris flow, hyperconcentrated flow, and flood with intense bedload, usually triggered by intense and short duration rainfall. In order to properly manage ...

Investigations of the Ianò and Maierato landslides, Calabria, southern Italy
In the winter of 2009-2010, after the previous winter 2008-2009 when widespread hydrogeological instabilities had affected the whole of Calabria, the same area was still hardly hit by numerous and heavier instability phenomena, punctual and areal. In the context outlined it was ordered by the Italian Government to draft a "Plan excerpt for urgent action" which covered, in particular, the main city of the region, Catanzaro (Ianò district), and ...
Micro-seismic network at the Carrel Hut on the Matterhorn
The permafrost degradation is a probable cause of the increase of rock instabilities and rock falls observed in recent years in high mountain areas. It causes the thaw of the ice filling rock discontinuities producing water that subsequently freezes again, inducing stresses that lead to rock falls. Rock-falls are among the most hazardous instability processes in high mountain environments because of their velocity and the difficulty to ...
Monitoring system in the framewok of the Interreg IV Project “Monitor II”
Debris-flow monitoring in instrumented areas is an invaluable way to gather field data that may improve the understanding of these hazardous phenomena, as well as for the development of warning systems. The number of monitoring sites and the amount of recorded data on debris flows, however, still remain limited if compared to landslides and fluvial sediment transport. This motivated the Autonomous Province of Bozen-Bolzano to implement a new ...
Innovative System for Monitoring and assessment of hIgh risk LANDslides
One of the main challenges in the field of engineering geology is the comprehension of the triggering mechanisms of landslides and the forecast of possible evolutionary scenarios in order to assess the correct mitigation measures. Landslides can be initiated by a variety of triggers: from earthquakes to meteorological events, including intense or prolonged rainfall, rapid snow melting, and variations of the surface temperature conditions. ...
Hazard posed by slope instability phenomena in Calabria
The territory of Calabria is affected by numerous landslides and, more generally, has a strong propensity to develop hydrogeological instability. A measure of this condition is provided by the data of the current PAI, limited to the examined areas (villages and households with more than 200 inhabitants), that identifies over 1700 high-risk situations and more than 700 at very high risk: a total of over 2,400 situations in which a hazard to the ...
Triggering and evolution of the San Benedetto Ullano landslide
With reference to landslides, Italy is exposed to high-risk conditions (Guzzetti, 2000). The abundant and prolonged rains fallen in the 2008-2009 and 2009-2010 wet seasons triggered numerous landslides in Calabria, mostly in its northernmost sector. Such geo-hydrological crises were severe enough to induce the Italian government to declare the State of Emergency on both ...
