ARchivio TEMatico Immagini Aerofotografiche Di Eventi

project-ARTEMIDE-evidenza-2 The IRPI Aerialphotografical archive consists of about 170000 aerial photographs of Northern Italy (1954-2005) useful for a stereoscopic vision. It also includes military flights (Royal Air Force) carried out during the Second World War. For some areas there are also rare aerial shots of the years 20, 30 and 40, often in diachronic form (5-10 years). The documentation refers to geo-hydrological events occurring on large areas and characterized ...

Role of climate change in the morphogenesis of glacial-periglacial environments and analysis of associated risks

project-ruolo-cc-evidenza-2 Climate change in the Greater Alpine Region is seriously affecting glacial and periglacial areas, especially for the presence of snow, glaciers and permafrost (cryosphere), with relevant consequences on slope stability. Cryosphere degradation, changes of the precipitation and temperature patterns and of the hydrological regimes, are some of the main terrestrial indicators of climatic change. Moreover, the increasing number of tourists and human ...

Debris-flow monitoring in the Alps

monitoraggio_debris_flow-evidenza 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 ...

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 ...

RiST2, the research go on

news-rist2-2018-evidenza The researches at high-elevation sites continues, thanks to the RiST2 project (co-financed by Fondazione CRT of Torino). The study area is the Bessanese glacial basin. The Alpine environment and in particular the cryosphere, is responding quickly and with great intensity to climate change. The air temperature increase observed in the Alps urge the scientific communities involved in natural instability studies to consider not only air ...

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 ...

Deep seated Gravitational Slope Deformation (DsGSD) analysis and criticalities assessment of the regional monitoring network of the landslides

evidenza-dgpv-giordan-cime-bianche The Aosta Valley region presents a landscape almost totally occupied by mountain. In this context, a number of meaningful landslides is present, which vary from rock falls to deep-seated gravitational slope deformation (DsGSD), passing for the complex landslides. The study of these phenomena, finalized to guarantee suitable standard of safety and to facilitate a compatible development, results a fundamental necessity for this ...

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 ...

RiST project: Scientific and Technological research in the Bessanese glacial basin (Balme, NW Italian Alps)

RIST-evidenza The Alpine environment, and in particular the high-altitude one, is responding quickly and with great intensity to climate change, through evidences of geomorphological, hydrological and ecological type. Mountain glacier shrinkage and related outcropping of rock walls and debris, changes of the precipitation and temperature patterns, are some of the main terrestrial indicators of climatic ...

SLOPES

progetto-slopes-evidenza This project is embedded within the framework of the three Ny-Ålesund flagships: ‘Kongsfjorden system’, ‘Glaciology’ and ‘Terrestrial system’. The study of slopes and landscape modifications under a changing climate, is needed to understand the dynamic interaction between the cryosphere, hydrosphere, geosphere and biosphere, and how geosuccession and biosuccession (colonisation) processes develop over time. Records of landscape ...
