Assessment Principles for Glacier and Permafrost Hazards in Mountain Regions
2022Abstract Glacier and permafrost hazards in cold mountain regions encompass various flood and mass movement processes that are strongly affected by rapid and cumulative climate-induced changes in the alpine cryosphere. These processes are characterized by a range of spatial and temporal dimensions, from small volume icefalls and ...

The Engineering Geology Hazards of Rock Glaciers
Environmental & Engineering Geoscience, 1985Rock glaciers are common, yet, because of the association with past periglacial and glacial activity, are often ignored as present day engineering hazards. As alpine development increases, rock glacier location and analysis becomes vital. Air and ground reconnaissance easily identifies rock glaciers using four characteristics: 1) slope angle somewhere ...

Velocity Changes of Rock Glaciers and Induced Hazards
2014Recent observations and geodetic measurements in the European Alps show that changes are occurring on rock glacier dynamics, ranging from moderate velocity variations to strong acceleration or even total collapse. These changes can be related to the ground temperature and to climate warming.

Glacier Fluctuations and Hazards
The Geographical Journal, 1987discussion of the types of hazards associated with climatically led oscillations in populated areas and their timing. The threat from such glaciers has diminished but not disappeared with the recession of the last century. The impact of the more dramatic oscillations of surging glaciers and those with floating tongues has been limited by their ...

Glacier Detachment Hazard Analysis in the West Kunlun Shan Mountains
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019In February 2018, we identified an unnamed glacier in the West Kunlun Shan mountains which showed crevasses extremely similar to the detachment patterns of two glaciers on the Western Tibetan Plateau near lake Aru Co before their catastrophic collapse.

Single pass InSAR missions for monitoring hazardous surging glaciers
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017Temporally resolved, 3-dimensional surface elevation data provide valuable insight into glacier dynamics, e.g. glaciers surges: short periods of rapid acceleration and mass transport which can pose significant hazard potential. Particularly in remote locations, such hazards can develop unobserved by the downstream communities at risk.

GLACIAL HAZARDS IN GLACIER NATIONAL PARK, MONTANA
Physical Geography, 1989The spatial and temporal aspects of glacial hazards in the Lewis and Livington Ranges of Glacier National Park, Montana are examined. Ice avalanches have historically been a hazard in the Park, and continue to be so from glaciers in cirques. Ice avalanches were more common and more widely distributed during and immediately after the Little Ice Age.

The 1981 – 1982 surge of Hazard Glacier, Yukon Territory
Canadian Journal of Earth Sciences, 1984A surge of Hazard Glacier, believed to have started in 1981, displaced ice as much as 0.7 km. Before the surge, ice thickness was measured by radio echo sounding and temperatures were taken in three holes to the glacier bed. The glacier is subpolar with 10 m temperatures near −5.4 °C, and temperature versus depth profiles show many anomalous features.

A Proposed Framework Approach for Mapping Glacier Hazard Zones
2019The main aim of this study is to propose a new ensemble framework model for the prediction of snow avalanche prone regions. The proposed approach is based on the following pillars: Support vector machine classifier (SVM) and recent state-of-the-art ensemble learning techniques, Bagging and MultiBoost.
