Glacier- and permafrost-related hazards represent a continuous and growing threat to human
lives and infrastructure in mountain regions. Present atmospheric warming especially affects
terrestrial systems with surface and subsurface ice involved. Changes in glacier and permafrost
equilibrium are shifting hazard zones beyond historical knowledge. Furthermore, human settlements
and activities extend towards endangered zones. As a result historical data alone are not sufficient
any more for hazard assessments and have to be combined with new observation and modelling
approaches.
The present session aims to address all kinds of glacier and permafrost hazards as related to e.g.
- glacier lake outbursts,
- ice and rock avalanches,
- glacier retreats or advances and fast glacier flow,
- destabilization of peri- and paraglacial debris reservoirs and rock walls,
- adverse effects of rock glaciers and other periglacial slope movements,
- frost heave and thaw settlement,
- triggering of glacier and permafrost hazards by earthquakes and volcanic activity, and
- combinations and chain reactions thereof.
We invite contributions related to
- processes,
- case studies and examples,
- techniques and strategies for mapping, monitoring, modelling,
- methods of hazard, vulnerability and risk assessment,
- methods of risk mitigation including styles and effectiveness of remedial works, and
- protocols for risk assessment and remediation.
The session is linked to the working group "Glacier and Permafrost Hazards in Mountains" by the
International Commission on Snow and Ice (ICSI) and the International Permafrost Association
(IPA) (See also www.geo.unizh.ch/gaphaz).
A corresponding meeting is planned in addition to the scientific session.
