In this paper, the updating of landslide inventory Tuscany region is presented. To achieve goal, satellite SAR data processed with persistent scatter interferometry (PSI) technique have been used. The leads to a consistent reduction unclassified landslides and an increasing active landslides. After updating, we explored characteristics new inventory, analysing distribution geomorphological features. Several maps elaborated, as sliding index or density map; also propose density-area map...
Landslide dams are rather common events in hilly and mountainous areas they occur when a landslide reaches valley floor closing the riverbed. If form lake basin, unstable can have catastrophic consequences upstream of populated regions. dam behavior is not completely understood yet, however several studies suggested implementing geomorphological index order to assess their formation evolution. These indexes result from composition two or more morphological attributes that characterize (e.g....
Abstract. In this work, we apply a physically based model, namely the HIRESSS (HIgh REsolution Slope Stability Simulator) to forecast occurrence of shallow landslides at regional scale. is distributed slope stability simulator for analyzing landslide triggering conditions during rainfall event. The modeling software made up two parts: hydrological and geotechnical. model on an analytical solution from approximated form Richards equation, while geotechnical infinite that takes unsaturated...
The study of past landslide dams and their consequences has gained a considerable significance for forecasting induced hydraulic risk on people property. Landslide are rather frequent in Italy, where broad climatic, geological morphological variability characterize different part the peninsula, have already been studied literature, focusing geographical regions with levels detail. In order to develop specific tools assess dam formation stability, first step is realize large data archive...
Global warming in high mountain areas has led to visible environmental changes as glacial retreat, formation and evolution of moraine dammed lakes, slope instability, major mass movements. Landslide dams are rather common the Cordillera Blanca Mountains Range, Peru, have caused large damages fatalities over time. The influencing rivers' dams' equilibrium, potential induced consequences, like catastrophic debris flows or outburst floods resulting from dam failures, can be hazards region....
Abstract The gravitational instability of hot material deposited during eruptive activity can lead to the formation glowing avalanches, commonly known as deposit-derived pyroclastic density currents (PDCs). These travel hundreds metres several kilometres from source at exceptionally high temperatures, posing a catastrophic hazard areas surrounding steep-slope volcanoes. occurrence PDCs is often associated with crater rim failure, which be triggered by various factors such magma thrust dike...
The Sciara del Fuoco (SdF) collapse scar at Stromboli is an active volcanic area affected by rapid morphological changes due to explosive/effusive eruptions and mass-wasting processes. aim of this paper demonstrate the importance integrated analysis multi-temporal remote sensing (photogrammetry, COSMO-SkyMed Synthetic Aperture Radar amplitude image) marine geophysical data (multibeam side scan sonar data) characterize main morphological, textural, volumetric that occurred along SdF slope in...
Abstract A complete landslide dam hazard management incorporates two assessment phases: the damming probability and breach hazard. prompt evaluation of stability is crucial during emergency to mitigate its consequences, but a reliable risk can be realized only after event has occurred, when available time very short. Therefore, it necessary develop tools able help in mapping spatial over large areas for land-use planning, order better constrain consequence analysis scenarios setting up...
Unmanned aerial vehicle (UAV) photogrammetry has recently become a widespread technique to investigate and monitor the evolution of different types natural processes. Fluvial geomorphology is one such fields application where UAV potentially assumes key role, since it allows for overcoming intrinsic limits satellite airborne-based optical imagery on side, in situ traditional investigations other. The main purpose this paper was obtain extensive products (digital terrain models (DTMs),...
Animal burrows in a river's earthen levee leads to water piping phenomena causing structural damage and eventual collapse during floods. Currently, the state of art comprises case studies that deal with management maintenance, while very few documents attempt at assessing possible animal-induced failure mechanisms. For latter, detection characterisation animal is crucial Electrical Resistivity Tomography (ERT) Ground Penetrating Radar are most employed geophysical techniques. Between 2017...
UAV-based photogrammetry is becoming increasingly popular even in application fields that, until recently, were deemed unsuitable for this technique. Depending on the characteristics of investigated scenario, generation three-dimensional (3D) topographic models may fact be affected by significant inaccuracies unless site-specific adaptations are implemented into data collection and processing routines. In paper, an ad hoc procedure to exploit high-resolution aerial multitemporal analysis...
In October 2023, during the Italian Civil Protection Week, in Eastern Lombardy (Italy) a large technical-thematic seismic exercise called “EXE.Lomb.Est 2023” was organized, with goal of testing response Regional system for post-earthquake damage assessment activities. Within this context, use an unmanned aerial (UAS), particular deployment multi-rotors UAS teams, has been tested as support rapid mapping area involving simultaneous participation different institutions units. Coordinated...
Abstract Steep alpine rock slopes undergoing deformation may give rise to concurrent landslide hazards of different type and magnitude. The underlying mechanisms instability are often challenging investigate due their inherent complexity; furthermore, they can occur on poorly accessible terrain, preventing the collection data by means traditional field techniques or even inhibiting awareness hazards. This paper focuses upon one such case, in which a major transportation corridor running...
Abstract. In this work, we apply a physically-based model, namely the HIRESSS (High REsolution Stability Simulator) to forecast occurrence of shallow landslides at regional scale. The final aim is set-up an early warning system scale for landslides. physically based distributed slope stability simulator analysing landslide triggering conditions in real time and large areas using parallel computational techniques. software can run real-time by assimilating weather data uses Monte Carlo...
Abstract. Central Asia regions are characterized by active tectonics, high mountain chains with extreme topography glaciers, and strong seasonal rainfall events. These key predisposing factors make large landslides a serious natural threat in the area, causing several casualties every year. The crests divided wide lenticular or narrow, linear intermountain tectonic depressions, which incised many of most important rivers also subject to major river flood hazard. This multi-hazard combination...
