In recent decades, InSAR data has been extremely helpful in identifying and delineating active landslides, as well as enhancing our understanding of geo-hydrological instability. However, due to the complexity and limitations of interpreting InSAR data, there is a need for guidelines to facilitate its operational use in detecting slow landslide ...
Italy is an extremely fragile territory, widely exposed to hydrogeological hazards affecting anthropic infrastructures and the natural environment. In this scenario, geomorphological maps, including the representation of the spatial distribution of landforms, have been used for a long time for the description of processes acting on the Earth’s surface. Geomorphological maps should represent the basic tool for the assessment of ...
Climate changes affecting the planet need to pay great attention to evaluate the related effects, primarily in mountain territories, first sentinels of climate change. The actively involvement of high-altitude refuges, a precious asset for weather and climate surveillance of the Italian mountains, need to increase and improve knowledges about climate change effects on these infrastructures, requiring specific assessment and investigation ...
Geodiversity refers to the variety of natural abiotic features, as the natural variety of geological (rocks, minerals), geomorphological (landforms, physical processes), hydrological and soil properties. The parameter “geomorphodiversity” is a measure of the dynamics of the Earth's surface and it has a key role in conservation of biodiversity and sustainability of ecosystems. Thus, it affects evolution of the biotic world and of human life. ...
Predicting the occurrence of rainfall-induced landslides is a crucial task for civil protection purposes. Several landslide early warning systems are currently operating worldwide at different spatial scales. In Italy, landslide alerts are issued for territorial units named Alert Zones, covering a few thousand km². Usually, regional-scale warning models rely on rainfall thresholds, which require a few parameters and provide clear results in ...
The Copernicus Sentinel-3 Surface Topography Mission (STM) provides extremely valuable surface elevation information over inland waters, sea ice and land ice, thanks to its SAR altimeter which retrieves high-resolution along-track elevation measurements, and to its orbit that covers high-latitude polar regions.
To ensure that these measurements can be used with confidence, and to maximize the return on investment of the Copernicus Sentinel-3 ...
The Aosta Valley is a small alpine region affected by numerous landslides, varying in size and type, ranging from isolated rock falls to rotational/translational slides up to extensive deep landslides. The study of such landslides, functional to a more effective risk management and to guarantee adequate safety standards, represents a primary necessity for a mountain territory like this ...
Geological-geotechnical monitoring systems are one of the most effective tools for landslide characterization, both in terms of landslide detection and for monitoring purposes. The regional monitoring network of Regione Lombardia represents an exemplary case in Italy, with as many as 44 landslides monitored, of which more than half in real time.
The management of monitoring networks and early warning systems represents a complex component, in ...
The documented effects of climate change and environmental degradation are a threat to human societies on European and global scales. Climate change may have an impact on water availability, may increase the threat of flooding and flash-floods, and will challenge coastal regions due to rising sea levels. All this will have impacts on the economy and society. The role of citizens and their skills become important both in limiting human impacts ...
Dal sito del Corriere della Sera, intervista (del 1 luglio 2021, articolo pubblicato il 7 luglio 2021) a Marta Chiarle, ricercatrice presso l’IRPI CNR di Torino, che presenta il “Catasto delle frane di alta quota nelle Alpi” recentemente pubblicato a cura del gruppo di ricerca ...
Landslides leave discernible signs on the land surface, most of which can be captured in remote sensing images. On the images the signs appear as modification of the photographic characteristics as tone, colour, mottling and texture, or/and as modification of morphological characteristics including shape, curvature, convexity and concavity. These signs are the landslide signature. Trained geomorphologists analyse remote sensing images and map ...
Climate change has a powerful impact on high-altitude Alpine sectors and glaciers. This impact often turns into an increase in instability processes that can lead to very high-risk conditions. These risk conditions can significantly affect the usability of areas characterized by intense tourist flows, making risk management very ...
Worldwide, landslides pose a serious threat to the population, causing fatalities, widespread damages, and significant economic losses. Different phenomena influence the stability of slopes and can cause landslides, among which the main factor is rainfall. Rainfall is strongly controlled and influenced by climate and its variations. Therefore, it is to be expected that climate changes influence slope stability at different temporal and ...
The use of remotely piloted aircraft systems (RPASs) in geosciences is often aimed at the acquisition of an image sequence to produce digital models and orthophotographs of the topographic surface. Such photogrammetric technique can be applied for rockfall hazard and risk assessment. To study rockfalls, an approach consists in the application of numerical models for the computation of rockfall trajectories. Data required for such simulations ...
River discharge is defined as the amount of water flowing through a river over a specified period of time. Its estimate is crucial for all the operations of hydraulic structures design, the territorial planning and the flood risk assessment and management. River discharge at a specific river cross-section is not a direct measurement, but it is calculated by measuring other hydraulic quantities such as the flow velocity and the water depth, i.e. ...
The researches and the experimentations carried out, in the learning field, by the IRPI Institute during the last years, started out initially in the field of geoethics, have allowed to set up principles and didactic tools that offer today practical and usable tools to significantly improve, in a relatively short period of time, the expressive, learning and assimilation capacities of students and adults.
The researches have been originally ...
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 ...
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 ...
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 ...
The Mar Piccolo basin is an internal sea basin located along the Ionian coast (Southern Italy), and it is surrounded primarily by fractured carbonate karstic environment.
In primarily karstic environments, infiltration is greater than runoff; in the karstic coastal Apulian aquifers, the groundwater discharge to the sea is more than two-fold greater than the surface discharge, notwithstanding the high discharges by wells. In such ...
Sinkholes occurrence is related to the presence of an underground cavity, from which instability starts and propagate upwards until causing the collapse of the surface soil layer. The cavity may have a natural or artificial origin. Natural caves are due to presence of soluble rocks, and are typical of karst settings, where most of the sinkholes occur for dissolution processes. Man has excavated Anthropogenic cavities, for different purposes and ...
Alluvial fans are known to be areas of high geomorphic activity, where debris flows and flash floods caused by intense and prolonged rainfall are a major hazard. In Calabria, southern Italy, alluvial fans are numerous. The exact age of the alluvial fans is seldom known, but most of the fans in Calabria are considered recent in age (Holocene).
Due to the significant increase in urbanization in the last two centuries, many alluvial fans are ...
Our AIS (Automated Inclinometer System) allows for fully automatic inclinometer measurements in standard boreholes. The deep measurements have multiple applications, including (i) evaluating the rate of deep-seated ground deformation in landslide areas, (ii) evaluating the volume of deep-seated landslides, and (ii) assessing landslide hazards.
The AIS is composed of an electronic control manager, an inclinometer probe (with traditional ...
Not all that flows in creeks is water. Debris flows i.e., surges in which solid particles move together with little water, may occur in steep mountain streams, mainly as a consequence of intense rainfall. Debris flows have a high kinetic energy, and may cause major damage if they encroach buildings, roads and bridges. They are also a primary cause of landslide casualties. The video below shows an example of debris flows.
The low ...
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 ...
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 ...
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 ...
Between the late 19th and early 21st century, in the Alps the average air temperature has increased by about 2 °C, more than twice the increase in temperature in the northern hemisphere, of 0.8 °C. In the same period, precipitation showed a tendency towards an increase in the northern part of the Alps, and a tendency towards a decrease in the southern sector of the Alps.
Since the end of the Little Ice Age (about 1850), glaciers in the ...
ALMOND-F is an innovative unit for the microseismic detection of debris flows using a network of geophones.
The microseismic detection of debris flows is more complex than other types of monitoring. Use of the geophones requires: (1) the selection of the level of amplification of the signal, which depends on the distance from the stream; (2) the selection of the sampling frequency of the seismic signal, which must be sufficiently high; (3) ...
Despite the large number and frequency of landslides and floods that affect our territories, and the information on landslides and floods available also online, the subject of geo-hydrological hazards remains poorly known to the Italian citizens. The lack of understanding reflects in the limited perception of the population on the geo-hydrological risks in Italy.
One reason for the lack of understanding is the way in which the subject of ...
Using long-term rainfall records obtained by the rain gauge network of the former Italian Hydrographic Service, in cooperation with colleagues in other CNR Institutes (ISAC and ISAFOM), we have studied the changes in the rainfall regimes in Calabria, Southern Italy.
Applying appropriate statistical methods, we checked the completeness of the historical records, verifying consistency and missing values in the records. We used the obtained ...
SM2RAIN is an innovative system for the estimation of the rainfall, based on measurements of the soil water content. SM2RAIN considers the soil as a natural rain gauge, and by measuring temporal variations of the soil water content, it estimates the rainfall falling on the soil, adopting a “bottom up” approach. Technically, SM2RAIN relies on the inversion of the soil water balance equation that computes the repartition of rainfall in ...
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 ...
La sperimentazione ad ampio raggio condotta negli ultimi anni per testare sul campo la funzionalità e l’efficacia della procedura semplificata per la rielaborazione dei ricordi traumatici (RINOEL) ha consentito di evidenziare con sempre maggior chiarezza gli effetti esercitati da tali ricordi sull’attenzione di una persona. La capacità di concentrazione di un individuo, e dunque la sua abilità di focalizzare l’attenzione, risente ...
Mass wasting is a threat to residential areas and infrastructure, causing widespread destabilization in alpine stream channels, also in relation to ongoing climatic changes. Although hillslope sediment supply represents a critical factor for stream channel stability during heavy rainstorms, there is a general lack of procedures for quantifying sediment availability and composition. Moreover, we lack validated empirical models for estimating ...

A Geo-hydrological event (EDId) (landslides, mass movements, floods, etc.) can result in a high social and economic impact, especially if it is generated by multiple simultaneous phenomena, when it is able to produce social hardships and economic damage characterized by important and lasting effects. The identification of the typical elements of the phenomena that can contribute to an EDId (typify) is essential to adequately define the risk ...
The management of emergencies, in particular those determined by natural events, is complex and must be able to use all the available cognitive elements. During emergencies, it is possible to acquire useful data regarding the processes that determine the same emergencies. These data can contribute to significantly improve planning and design of prevention ...
The Maierato landslide (Vibo Valentia Province) is a complex movement, which involved a significant thickness of geomaterials (rocks and soils) and rapidly flowed away for one kilometre. Owing that, the surrounding zone is interested by the same geological settings that predisposed the Maierato landslide, it is useful to identify any elements indicative of the presence of instabilities that can be triggered and evolved as the Maierato ...
