Flexible protection barriers are the most widespread passive mitigation system against natural hazards such as rockfall. These structures dissipate the kinetic energy of the rock block through inertial deformation. When subject to significant loads, the steel wires composing the structure undergo plastic hardening and non-reversible deformation. Wh...

This study investigates the subsurface urban heat island (SUH...
Article
The relationship between landslides and rock mass strength is fundamental for assessing landslide hazards. Some researchers have proposed that there is an inverse relationship between the number of landslides and rock mass strength. However, in some tectonically active mountain ranges, higher rates of landsliding appear to be associated with greate...

The risk management of rainfall-induced landslides requires reliable rainfall thresholds to issue early warning alerts. The practical application of these thresholds often leads to misclassifications, either false negative or false positive, which induce costs for the society. Since missed-alarm (false negative) and false-alarm (false positive) cos...

Earthquakes are – amongst many others – one type of triggering factors for mass movements in mountainous regions such as landslides, deep-seated gravitational slides (DSGSD), rockfalls, mudflows, etc. Hence, the emerging hazard would require an area-wide assessment of seismogenic impact to better apprehend the interplay of different triggering fact...
Article
Full-text available
Large slow rock-slope deformations, including deep-seated gravitational slope deformations and large landslides, are widespread in alpine environments. They develop over thousands of years by progressive failure, resulting in slow movements that impact infrastructures and can eventually evolve into catastrophic rockslides. A robust characterization...

Landslide size controls the destructive power of landslides and is related to the frequency of occurrence, with larger landslides being less frequent than smaller ones. For this reason, the analysis of landslide size is essential for landslide hazard assessment. We analyse six earthquake-induced landslide inventories with earthquake magnitude rangi...
Article
Field and monitoring evidences show that deformation in a rockslide is predominantly localized along a basal shear zone. Mineralogic, grain size, thickness, and fabric characteristics of the shear zone control its behavior and the possible evolution of the rockslide from a slow creeping to a fast moving one. Standard experimental tests can characte...
