Geostructures, dynamics and risk mitigation of high-altitude and long-runout rockslides

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Long-runout rockslides at high altitude could cause disaster chain in river basins and destroy towns and major infrasturctures. This paper firstly explores the initiation mechanism of high-altitude and long-runout rockslides.

Quantifying the slip rates, spatial distribution and evolution of active normal faults from geomorphic analysis: Field examples from an oblique-extensional graben, southern Turkey [PDF]

open access: yes, 2009
Quantifying the extent to which geomorphic features can be used to extract tectonic signals is a key challenge in the Earth Sciences. Here we analyse the drainage patterns, geomorphic impact, and long profiles of bedrock rivers that drain across and ...

Present-day stress orientations and tectonic provinces of the NW Borneo collisional margin [PDF]

open access: yes, 2010
Extent: 15p.Borehole failure observed on image and dipmeter logs from 55 petroleum wells across the NW Borneo collisional margin were used to determine maximum horizontal stress (σH) orientations; combined with seismic and outcrop data, they define seven

Middle to Late Miocene Contractional Deformation in Costa Rica Triggered by Plate Geodynamics [PDF]

open access: yes, 2017
Contractional deformation in Costa Rica is usually attributed to the subduction of the aseismic Cocos Ridge. In this work, we review the evidences for contraction in the middle to late Miocene, prior to the arrival of the Cocos Ridge at the Middle ...

Long-runout fluidization disaster simulation analysis of clastic landslide under heavy rainfall: A case study of the Niuerwan landslide

open access: yesDizhi lixue xuebao, 2022
The frequent occurrence of remote landslide disasters under heavy rainfall in the mountainous area with sand-mudstone strata in southwest China is a critical issue to be solved in disaster prevention and mitigation.

Stress buildup in the Himalaya [PDF]

open access: yes, 2004
The seismic cycle on a major fault involves long periods of elastic strain and stress accumulation, driven by aseismic ductile deformation at depth, ultimately released by sudden fault slip events. Coseismic slip distributions are generally heterogeneous

Opposing shear senses in a subdetachment mylonite zone: Implications for core complex mechanics [PDF]

open access: yes, 2010
[1] Global studies of metamorphic core complexes and low‐angle detachment faults have highlighted a fundamental problem: Since detachments excise crustal section, the relationship between the mylonitic rocks in their footwalls and the brittle deformation

Segmentation of the active Liumugao Fault, NE Tibetan Plateau as revealed by DEM-derived geomorphic indices

open access: yesGeosystems and Geoenvironment, 2022
As the secondary fault of the Niushoushan-Luoshan Fault Zone, the Liumugao Fault records the northeastward expansion of the Tibetan Plateau. Based on WorldDEM data, 11 rivers (R1-R11) that flow across the Liumugao Fault and their drainage basins were ...

Geomorphic signal of active faulting at the northern edge of Lut Block. Insights on the kinematic scenario of Central Iran [PDF]

open access: yes, 2016
Recent works documented Neogene to Quaternary dextral strike-slip tectonics along the Kuh-e-Sarhangi and Kuh-e-Faghan intraplate strike-slip faults at the northern edge of the Lut Block of Central Iran, previously thought to be dominated by sinistral ...
