Looking at the rock masses and rock falls: new views and prospects
11. April 2016

In recent years there has been a remarkable development of techniques for the detection and remote acquisition of features of rock masses, with great speed, accuracy and resolution. The two most commonly used are the 3D laser scanner and digital photogrammetry, which allow the extraction of geometric parameters of the rock mass surface such as the joint sets, their orientations, spacing, and persistence. These techniques ... more

Probabilistic Landslide Hazard Analysis
20. April 2015

In this speech, a general framework for probabilistic landslide hazard analysis is presented. With respect to other quantitative hazard assessment approaches, this probabilistic landslide hazard analysis has the advantage to provide hazard curves and maps, and to be applicable to all typologies of landslides, if necessary accounting for both their onset and transit probability.  .......more

International Lecture 2014

Large-scale disaster risk assessment and diversity of natural disaster systems
16. June 2014
, Peijun SHI

Guided by the Regional Disaster System concept and starting with the conventional risk assessment model and taking into consideration the disaster chain characteristics of large-scale disasters, this speech will introduce a risk assessment model of large-scale disasters to adequately reflect the intensity of hazards, the vulnerability of exposure, and the stability of hazard-formative environment......mehr

International Lecture 2013

Benefits and Limitations of quantitative Risk Assessment in dealing with Natural Hazards
07. Jänner 2013
, Farrokh Nadim

Society is exposed to both natural and human-induced risks. While the risk posed by natural hazards can never be eliminated, our goal must be to reduce the risk to levels that are tolerable. Quantitative Risk Assessment (QRA) is a powerful tool for understanding the main drivers of risk and choosing the optimal risk mitigation strategy with the resources available.....mehr

International Lecture 2011

Challenges in Landslide Hazard and Risk Assessment
19. Jänner 2011
, Fausto Guzzetti

Determining landslide hazards and the associated risk requires information on where and when landslides will occur, and how destructive they will be. In the past decades, substantial progresses were made on determining where landslides are expected. We are less capable of predicting when landslides occur, and the types of damage they cause. Also, the effects of climate and environmental changes on the location,....mehr

International Lecture 2009

The Response of Geomophic Systems to Global Environmental Change: Implications for Hazard and Risk
23. November 2009
, Michael Crozier

Rapidly changing global processes responible for destabilising geomorphic systems are identified and examined with reference to specific contemporary contexts, including fluvial, coastal, hillslope and agricultural systems. Compared to the chornic effects of climate change, human interventions can be acute, far reaching and govern system behaviour by amblifying or dampening system response to change....mehr

International Lecture 2008

Hazard, Risk and Disaster Reduction: State of the Art
15. Dezember 2008, David Alexander

This talk will review the current state and developing trends in disaster
risk reduction and emergency preparedness. It will do so using models of
the institutions and processes involved.With regard to both natural and
anthropogenic hazards, particular attention will be devoted to the
relationship between science and society. ...mehr
