What’s underneath?

focus-cosa-c-e-sotto-evidenza When soil behaviour is studied, whether landslide soils are concern, levee materials or foundations, the problem regarding how much and how reliable information about the soil properties we have available has to be addressed. Understanding “what’s beneath” the visible surface is fundamental, yet complicated. Drillings are performed to analyse the stratigraphy of soils (the order and the thickness of the different soil levels) and ...

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 ...

Historical landslides and floods in Calabria

focus-petrucci-evidenza-1 Landslides and floods tend to hit places that by their nature and geographic location are more likely than others to be damaged. Knowing the location of these places, and how they have been affected in the past by landslides and floods, allows to draw damage scenarios for possible future events. For years, we have studied historical landslide and flood events in Calabria. Our investigations have allowed us to reconstruct a unique historical ...

Earth observation and climate change

How we map landslides

focus-mappatura-inventari-evidenza A landslide is the movement of a mass of rock, debris or earth along a slope under the influence of gravity. Landslides pose serious threats in many areas of the world, and knowing their location, distribution and classification is important for land use planning. Landslide identification and mapping is a fundamental activity for an effective defence from the damage caused by landslides to the population and to structures and the ...

Preventive evaluation of land instability hazards

project-vapit-evidenza The urbanisation of seismically active areas, coupled with the ongoing change in climate patterns, require a shift in the approaches to land/infrastructure instability hazard assessment and risk reduction. This is particularly relevant in seismically active regions where the recurrent damage from landsliding, subsidence and ground deformations can be widespread. Geotechnical investigations and in situ monitoring of land prone to instability are ...

SARF Liguria

Rainfall thresholds can be used in early warning systems for the prediction of the occurrence of rainfall-induced landslides. To respond to a request of the Italian national Department for Civil Protection (DPC), CNR IRPI designed and developed SANF, an Italian acronym for National Early Warning System for ...

Hydrological monitoring and prediction of shallow landslides through remote sensing observations

project-LANDHYDRO-evidenza Rainfall-induced shallow landslides and floods are the most common and dangerous natural hazards, mainly due to their high temporal frequency, which causes fatalities and high economic damage worldwide. Climate changes will exacerbate this critical framework since an increase in extreme weather events is ...

Landslide monitoring Innovative methods and instruments

project-diati-evidenza The development of new systems for monitoring of landslides is often the synthesis of geomatics and applied geology. In particular, the development of innovative low-cost systems must have a strong geomatics and technological component supported by the definition of required elements done by end users (engineering geologists). The development of low-cost monitoring systems can represent a strategic choice, above all, to guarantee an increasing ...

Cartografia delle frane nell’area dell’invaso di Casanuova (PG)

project-l-eaut-area-evidenza The reservoir of Casanuova on the Chiascio river, Central Umbria, occupies an area affected by numerous landslides, already identified in the regional cartographies. However, the potential interaction between the evolution of landslides and the reservoir is not evaluable because the available landslide inventories are not updated and do not contain information on the morphological evolution over time of the slopes that drain into the reservoir. ...

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

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.

SARF Sardegna

evidenza-sarf-sardegna 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 ...
