Fragmentation is a common phenomenon in complex rock‐avalanches. The fragmentation
intensity and process determines exceptional spreading of such mass movements …

Abstract Knowledge of the processes and effects of the block‐grain phase transition in a
fragmented system is essential for investigating rock avalanches. Several series of …

Sudden freefall is very common in high-velocity and long-runout rockslides. The
combination of freefall and joints (a rock mass structure) may cause a high degree of …

Joint structure and sudden free-fall are very common in rock avalanches. But their
contributions to fragmentation and subsequent runout are not clear. Previous studies …

In this paper the effects of size-segregation on flow's mobility and final morphology of
axisymmetric collapses of dry, cohesionless, natural polydisperse grains, were …

Risks associated with large landslides pose a severe threat to human life and property.
Hence, the creep phase, the signal before the occurrence of large landslides, plays a …

The speed, distance and energy evolution of rapid and long-runout landslides are crucial
indicators for evaluating the characteristics of these catastrophic landslides. The Shuicheng …

Rockslides at high elevations often transform into rock avalanches due to fragmentation,
posing a significant threat. However, the underlying mechanism for the high mobility of rock …

Catastrophes are often caused by friction weakening, as shown by the empirical volume
effect of landslides. We use velocity-dependent, normal stress-dependent, power density …

The fracturing and fragmentation of rock blocks are important phenomena that occur
ubiquitously during the propagation of rock avalanches. Here, the movement of a …
