Rockfall is an extremely rapid process involving long travel distances. Due to these features,
when an event occurs, the ability to take evasive action is practically zero and, thus, the risk …

There is an increasing need for quantitative rockfall hazard and risk assessment that
requires a precise definition of the terms and concepts used for this particular type of …

This paper presents recommended methodologies for the quantitative analysis of landslide
hazard, vulnerability and risk at different spatial scales (site-specific, local, regional and …

Geographic information system (GIS) modeling is used in combination with three-
dimensional (3D) rockfall process modeling to assess rockfall hazards. A GIS extension …

Rockfall risk analysis for mitigation action design requires evaluating the probability of
rockfall events, the spatial probability and intensity of impacts on structures, their …

Rockfall phenomena represent a major hazard in mountainous areas because they can
cause severe damage to infrastructure and buildings as well as serious injuries and …

The impact-induced rock mass fragmentation in a rockfall is analyzed by comparing the in
situ block size distribution (IBSD) of the rock mass detached from the cliff face and the …

We present a general framework for probabilistic landslide hazard analysis. With respect to
other quantitative hazard assessment approaches, this probabilistic landslide hazard …

In order to enhance the detection of prospective rock falls in calcareous cliffs, 25 rock falls
have been described in a more detailed way than for an inventory. They are representative …

Rockfall propagation areas can be determined using a simple geometric rule known as
shadow angle or energy line method based on a simple Coulomb frictional model …
