The evolution of the shear resistance at the base of a coherent landslide body can effectively control its dynamic behavior. High‐velocity rotary shear experiments have allowed scientists to explore stress‐strain conditions close to those found in large landslides and faults. These experiments have led to two alternative models being proposed, which describe the evolution of the shear resistance through friction laws that depend either on normal stress or on velocity. Here, we discuss an… 
Mineralogical Analysis of Selective Melting in Partially Coherent Rockslides: Bridging Solid and Molten Friction
Frictional shearing along the basal slip surface is the main energy dissipation mechanism in coherent landslides, which undergo little internal deformation during runout. Most landslide bodies,
Scenario simulation of the geohazard dynamic process of large-scale landslides: a case study of the Xiaomojiu landslide along the Jinsha River
Large-scale landslides often cause severe damage due to their long run-out distances and having disaster chain effects. Scenario simulation has been adopted in the current work in order to analyze
Landslide Zone Investigation by Determining Cracks and Cracks Compressive Strength Test in Waru District, Pamekasan Regency
Landslide zone investigation has been conducted using geoelectricity to determine the number of cracks and using a compressive strength test to determine compressive strength cracks. The result of
Dynamic Analysis of the High-Speed and Long-Runout Landslide Movement Process Based on the Discrete Element Method: A Case Study of the Shuicheng Landslide in Guizhou, China
On July 23, 2019, a high-speed and long-runout landslide occurred in Jichang Town, Shuicheng County, Guizhou Province, China, causing 42 deaths and 9 missing. This paper used the discrete element


Shear‐Rate‐Dependent Behavior of Clayey Bimaterial Interfaces at Landslide Stress Levels
The behavior of reactivated and first‐failure landslides after large displacements is controlled by the available shear resistance in a shear zone and/or along slip surfaces, such as a soil‐bedrock
Frictional velocity-weakening in landslides on Earth and on other planetary bodies.
This work proposes an empirical velocity-weakening friction law under a unifying phenomenological framework applicable to small and large landslides observed on Earth and beyond and shows that friction decreases with increasing volume or, more fundamentally, with increasing sliding velocity.
Long runout landslides: The role of frictional heating and hydraulic diffusivity
Natural landslides often exhibit surprisingly large travel distances, and an unexplained decrease in apparent friction coefficient H/L (where H is the drop height and L the travel distance) with
High‐velocity frictional properties of a clay‐bearing fault gouge and implications for earthquake mechanics
[1] Frictional properties of natural kaolinite-bearing gouge samples from the Median Tectonic Line (SW Japan) have been studied using a high-velocity rotary shear apparatus, and deformed samples have

Two-dimensional landslide dynamic simulation based on a velocity-weakening friction law
Surprisingly, hypermobility (high velocity and long run-out) is a remarkable feature of large landslides and is still poorly understood. In this paper, a velocity-weakening friction law is
Thermal effects in landslide mobility
The paper describes a thermo-hydro-mechanical formulation to model thermally induced effects due to the irreversible work input generated during soil deformation. The model was implemented into a
Dynamic thermo-poro-mechanical analysis of catastrophic landslides
In this paper a dynamic analysis is presented of the early stages of an earth slide, considering two mechanically coupled substructures: (a) the rapidly deforming shear band at the base of the slide,
Moisture‐related weakening and strengthening of a fault activated at seismic slip rates
From high‐velocity friction experiments on gabbro rock at a rate of 85 mm/s, we found that a fault with a thin gouge layer experienced slip weakening with a drop of about 80% in the friction
Velocity‐dependent frictional weakening of large rock avalanche basal facies: Implications for rock avalanche hypermobility?
To characterize the hypermobility mechanism of rock avalanches, a series of rotary shear tests at different shearing velocities (Veq) ranging from 0.07 m/s to 1.31 m/s and at a normal stress of 1.47
