Probabilistic prediction of rock avalanche runout using a numerical model. [PDF]

Landslides, 2022
Rock avalanches can be a significant hazard to communities located in mountainous areas. Probabilistic predictions of the 3D impact area of these events are crucial for assessing rock avalanche risk.

Identification of a Quaternary rock avalanche deposit (Central Apennines, Italy): Significance for recognition of fossil catastrophic mass-wasting. [PDF]

Sedimentology, 2022
Whereas deposits of extremely‐rapid, ‘catastrophic’ mass wastings >105 m3 in volume (for example, the Marocche di Dro rock avalanche in the Southern Alps and the Flims rockslide in the Western Alps) are easily recognized by their sheer mass and blocky ...

Insights into the Movement and Diffusion Accumulation Characteristics of a Catastrophic Rock Avalanche Debris—A Case Study

Remote Sensing, 2023
In this study, the 1991 rock avalanche, in Touzhai, Zhaotong, Yunnan, China, was considered the study object. The investigation of the landslide accumulation body revealed that the Touzhai rock avalanche accumulation body has the characteristics of wide ...

The Flims rock avalanche: structure and consequences

Swiss Journal of Geosciences, 2022
The Flims rock avalanche has a gliding surface that cuts down section in a limestone sequence and does not follow a weak horizon. The gliding surface is parallel to bedding and/or to the penetrative Alpine foliation in the limestone that is characterized

Particle Project Correction for Rock Avalanche: Particle Crushing in Aerzhai Rock Avalanche, China [PDF]

Lithosphere, 2022
Strong fluidized rock avalanches with various particle sizes are one of the typical disasters in the mountainous area of southwestern China. Statistical analysis on rock avalanche particles can help understand the traveling behavior, distance, and ...

Experimental and numerical study on movement and accumulation behaviour of rock avalanche by simulating actual 3D terrain conditions [PDF]

Scientific Reports
Fluidization is an important aspect of a rock avalanche, which differs significantly from a common collapse. In general, it results in a rock avalanche with a large velocity and area of deposition, both of which are frequently affected by terrain ...

Dynamic Simulation of Rock‐Avalanche Fragmentation

Journal of Geophysical Research: Earth Surface
AbstractFragmentation is a common phenomenon in complex rock‐avalanches. The fragmentation intensity and process determines exceptional spreading of such mass movements. However, studies focusing on the simulation of fragmentation are still limited and no operational dynamic simulation model of fragmentation has been proposed yet.

Slope Failure in a Period of Increased Landslide Activity: Sennwald Rock Avalanche, Switzerland

Geosciences, 2021
The Säntis nappe is a complex fold-and-thrust structure in eastern Switzerland, consisting of numerous tectonic discontinuities and a range of hillslopes prone to landsliding and large slope failures that modify the topography irreversibly.

Influence of path materials on rock avalanche dynamics in the Nayong case study [PDF]

Scientific Reports
Rock avalanches are highly destructive geological hazards marked by sudden onset, rapid acceleration, and substantial material entrainment. These characteristics render the investigation of their kinematic processes particularly challenging and complex ...

Evolution of events before and after the 17 June 2017 rock avalanche at Karrat Fjord, West Greenland – a multidisciplinary approach to detecting and locating unstable rock slopes in a remote Arctic area [PDF]

Earth Surface Dynamics, 2020
The 17 June 2017 rock avalanche in the Karrat Fjord, West Greenland, caused a tsunami that flooded the nearby village of Nuugaatsiaq and killed four people.
