Remote Sensing Technologies For Monitoring Climate Change Impacts On Glacier- And Permafrost-Related Hazards, Andreas Kääb, C. Huggel, L. Fischer
Geohazards
Glacier- and permafrost-related hazards represent a continuous threat to human lives and infrastructure in high mountain regions. Because the surface and subsurface ice involved is generally close to melting conditions, glacier and permafrost hazards are particularly sensitive to climate changes. The present shift of cryospheric hazard zones due to atmospheric warming, process interactions and chain reactions, and the potential far reach of glacier disasters make it necessary to apply modern remote sensing techniques for the assessment of glacier and permafrost hazards in high mountains. In this contribution we provide an overview of different hazard types and how air- and space-borne …

Influence Of Degrading Permafrost On Landsliding Processes: Little Salmon Lake, Yukon Territory, Canada, R. Lyle, D. Jean Hutchinson
Geohazards
A landslide inventory was carried out for the Little Salmon Lake area, Yukon Territory, Canada, in response to observations of several new landslides in the area, suspected to be the result of degrading permafrost. The largest of these landslides, the Magundy River bi-modal flow-slide, has progressed over the last decade until it now involves over 1x106 m3 of material. The inventory is based on terrain mapping and field work, and includes multiple landslide types. The field work provided the opportunity to examine the slides, ground truth the map, and to examine the progression of the landslide, as well as the …
