Earthquake-induced landsliding
… of life and property losses associated with landsliding, the perturbation and recovery of landscape properties after shaking, and the long term topographic evolution of mountain belts. Several of these aspects have been addressed recently through individual case studies but additional data …

Deep-seated bedrock landsliding in Grand Canyon's Surprise Valley area
The effects of large-scale landsliding on the continental-scale Colorado River system in Grand Canyon remain poorly understood. This paper describes deep-seated bedrock landslides in the Surprise Valley area by combining detailed mapping, volume-balanced cross-sections, strath terrace heights, and …

Landsliding and sediment dynamics following the 2008 Wenchuan Earthquake in the Beichuan area of China
Extensive and widespread landsliding is a common feature in a post-earthquake mountainous environment. The intense seismic shaking of an earthquake leaves the ground destabilised and thus very susceptible to slope failure. In addition to co-seismic landsliding, many slopes retain the high potential …

FIVE YEARS AFTER THE OCTOBER 8, 2005 KASHMIR EARTHQUAKE: ASSESSING POST-SEISMIC LANDSLIDING PROCESSES BETWEEN 2005 AND 2010
… 2005 KASHMIR EARTHQUAKE: ASSESSING POST-SEISMIC LANDSLIDING PROCESSES BETWEEN 2005 AND 2010 Chair: Ulrich Kamp Abstract The October 8, 2005 Kashmir earthquake triggered thousands of landslides at different scales through the Hazara-Kashmir region of Northern Pakistan. Within a few months after …

Rimforest Landslides, San Bernardino Mountains, Southern California
… cracks in the adjacent area indicate that active landsliding may be spreading. Landsliding in this area had its origin most likely with the uplift of the San Bernardino Mountains and has continued with periods of active movement associated with heavy precipitation and seismic activity separated by …

Distribution, causes and nature of natural landslides in Devon and Cornwall
… studies and is not a true representation of landsliding in an area. The aim of this research was to identify landslide environments correlated with landslide frequency and character and through this develop a landslide susceptibility map. Analyses were undertaken so that distinct inland and …

Controls on the distribution of landslides triggered by the 2008 Wenchuan earthquake, Sichuan Province, China
Landsliding is the dominant mass wasting process in upland areas where the rate of river incision is higher than that of rock weathering of hillslopes. Although progressive erosional processes can provide sufficient conditions for slope failure, the majority of landslides are induced by …

New methods for <i>in situ </i>measurement of mechanical root-reinforcement on slopes
… can increase the resistance of slopes against landsliding. The mechanical contribution of roots to the shear strength of the soil is however difficult to measure in situ. Existing methodologies are time-consuming and therefore not suitable to quantify spatial variability on the slope. …

Mineralogy, Chemistry & Flux of Suspended Sediments in Himalayan Rivers
… it is shown in this thesis that coseismic landsliding following the 2015 Gorka earthquakes resulted in an increase in the erosion and sediment fluxes above “baseline” levels in the Kosi River. Sediments collected within the Himalayan Range immediately following the earthquake (June to …

Late quaternary climate changes and landscape evolution in the Northwest Himalaya : geomorphologic processes in the Indian Summer Monsoon Domain
… of the Sutlej River resulted in deep-seated landsliding. Landslides were exceptionally large, mainly due to two processes that I infer for this time: At the onset of the intensified monsoon at 9.7 ka BP heavy rainfall and high river discharge removed material stored along the river, and …

The behaviour of a structurally complex clay from an Italian landslide

A Comparison of GIS Approaches to Slope Instability Zonation in the Central Blue Ridge Mountains of Virginia

Probabilistic Modeling of Shallow Landslides at Regional Scales

This physical model is integrated with a statistical model relating observed …
