Mass wasting and the Coriolis effect on asteroid Vesta
… the influence of the Coriolis force on mass motion related to the Rheasilvia impact basin on asteroid (4) Vesta's southern hemisphere. The giant basin is 500km in diameter, with a centre which nearly coincides with the rotation axis of Vesta. The Rheasilvia basin partially overlaps an …

Icy Satellite Tectonic, Geodynamic and Mass Wasting Surface Features: Constraints on Interior Processes and Evolution
<p>Empirical data collected from mapping campaigns combined with modeling of geologic processes improves our understanding of planetary geology. Many planet- or satellite-scale processes cannot be reproduced in labs, thus analyzing surface features provides insights to confirm, discount, or improve …

Effect of mass wasting on soil organic carbon storage and coastal erosion in permafrost environments
… affected land are characterised by intense mass-wasting processes such as solifluction, active-layer detachments and retrogressive thaw slumping. Our aim is to assess the influence of mass wasting on SOC storage and coastal erosion. We studied SOC storage on Herschel Island by analysing …

Effect of Earthquake and Human Migration on Land Cover and Mass Wasting from The 2010 Haiti Earthquake
… millions of people and drastically induced mass wasting. The purpose of this study is to explore comprehensive relationships between population displacement and landslide frequency by comparing land use and land cover (LULC) maps of pre- and post-earthquake. To assess the impact of …

Applying Wetland Rating Systems to Assess Functions of Depressional Wetlands Created by a Mass Wasting Feature, Table Mountain, Washington
… Swauk Watershed has been primarily controlled by mass wasting events, which includes landslide activity. Landslide activity has been the primary influential process in shaping the landscape where wetland systems have formed on the surface of landslide deposits. The wetland sites used in this …

The Economic Impact of the Oso Landslide: A Hedonic Approach
Mass wasting, or landslides, commonly occurs in Washington State, posing risk to individuals residing in the area. The 2014 Oso landslide, the deadliest mass-wasting event in United States history, increased awareness for mass-wasting hazards in western Washington. Studying single-family homes from …

Comparison of Landslides and their Related Outburst Flood Deposits, Owyhee River, Southeastern Oregon
… through different lithologic units, the style of mass wasting changes from large slump events and small rock falls to large earthflows. The change in mechanism of mass wasting from upstream to downstream seems to depend on several factors: (1) the ratio of the basalt cap to the exposed underlying …

GIS Modeling of the Prominent Geohazards in Arkansas
… fold includes a novel triggerless approach for mass wasting susceptibility modeling applied to the Boston Mountains in NW Arkansas, and the second fold is a GIS-based regression modeling of the extreme weather patterns at the state level. Each study fold is presented in this thesis as a separate …

Rimforest Landslides, San Bernardino Mountains, Southern California
… the 1920's to 1988 the primary activity has been mass wasting by rockfall in highly fractured quartz monzonite. Tension 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 …

Mass-transport deposits on Mediterranean continental margins
Extensive mass transport deposits and multiple slide scars testify widespread and recurrent submarine sediment failures occurring during the late Quaternary on the SW-Adriatic and SE-Sicilian margins. These mass movements and their consequences contributed to shape the continental slopes and fill …

Heat flow and tectonics of the Ligurian Sea basin and margins
… After assessing local thermal disturbances (mass-wasting, microtopography, and salt refraction), positive heat flow corrections are made for multi-lithologic sedimentation histories and glacial paleotemperatures. Using boundary-layer cooling models, equilibrium heat flow estimates support …

Geology of Clover Hollow and surrounding area, Giles and Craig Counties, Virginia
… 10 percent of the area, is the result of great mass-wasting which may have begun as early as Late Cretaceous time. Dominant contributors to the colluvium are the Silurian Tuscarora, Rose Hill, and Keefer sandstones. Northwest ridge slopes are extensively covered with colluvium as compared to …

Late Weichselian and Holocene Glacimarine Sedimentation and Environments in Kejser Franz Josephs Fjord and On The Adjacent Continental Margin, East Greenland
… Greenland, sea ice rafting and pelagic settling. Mass wasting is recognised by the prescence of debris flows, which are derived from the rapid and unstable build-up of large volumes of glacigenic sediment. Mass wasting events are intermittent, vary from small scale to large scale., and are derived …

Caracterização das unidades sísmicas, processos sedimentares e idade do cânion Almirante Câmara, bacia de Campos
… In the slope it was evident the occurrence of mass wasting/mobilization. In the upper slope the reflectors are, frequently, inexistent due to the presence of intense faulting. In the middle slope the sedimentary package is well preserved and it is possible identification of main units and …

Glacial geology of western Wells County, North Dakota
… only slightly by post-glacial erosion and mass wasting.</p> <p>The southern one-third of the area is characterized by randomly-oriented mounds of till or dead-ice moraine. The dead-ice moraine originated when a large mass of stagnant ice ablated after typical glacial depositional features …

Spatial Analysis of Soil Creep Rates on Mount Sequoyah, Fayetteville Arkansas
… a deeply dissected plateau. The area is prone to mass wasting, which is the general downslope movement of sediments, soils, and rock through different processes that cause instabilities along a hillslope, and in its soil and loose rubble mantle. For this study, we looked at soil creep, which is …

Beryllium-10 derived erosion rates from the Hangay Mountains, Mongolia: landscape evolution in a periglacially-dominated continental interior
… the lack of observed evidence of recent or old mass wasting events that mobilize sediment and bedrock with much lower cosmogenic concentrations that cause underestimations of erosion rates. Basin-average erosion rates observed in seven basins across the eastern Hangay Mountains range from 12 …

Debris flows on Earth and Mars
… ascertained the geomorphic “fingerprint” of mass wasting, debris flow and pure water flow on Earth. Using these methods, I then confirmed that gullies on Mars contain the signature of debris flow. In addition, these investigations revealed a strong climatic signal in gully development. …

Evaluation of Coupled Erosional Processes and Landscape Evolution in the Teton Range, Wyoming
… The focus of erosion by glacial, fluvial, or mass wasting processes is highly sensitive to small changes in boundary conditions, therefore spatial and temporal variability can be high when observed over short time scales. This work evaluated methods for dissecting the history of complex alpine …
