Please feed the list with other phenomena and resources.

=== Rockfall ===
*'''r.rockcone''' (soon in [http://svn.osgeo.org/grass/grass-addons/ GRASS-Addons])
Rockcone implement a quick and low-cost determination of areas endangered by rockfalls following an heuristic approach: a block tarting from a source will travel down the slope and stop at the intersection point of the topography with a so called energy line drawn from the source point and making an angle φ with horizontal.

*'''r.sass3D''' (in development by the [http://www.ist.supsi.ch IST-SUPSI])
Sass3d is 3D rock fall model accounting for flying routine (air trajectory), rebound routine (energy loss) & rolling routine (equivalent sliding approach).

*'''r.dfw'''
Is an empirical model to estimate areas involved by the diffusion of the debris. It uses a Monte Carlo approach based on wolkers. The outputs are raster estimates of velocity, sedimentation height, and number of random walk. The Perla velocity model is applied.

This work shows the application and the validation of a procedure in GRASS to realize tsunami inundation maps based
on the morphological characteristics, the vegetation and the settlements of the analyzed coast. Such a procedure, already
illustrated in the VII GRASS Italian Users Meeting, and then improved, allow the estimation of the maximum vertical
height of the tsunami waves hitting the coast (run-up) and the subsequent diffusion over the inland areas, as a function
of the morphology, the vegetation, and the urbanization of the coastal area. The model, already successfully applied for
the ligurian coast, has to be tested in different areas in order to validate a global applicability. For this reason the
selected case study was the Caribbean island of St. Lucia. Based on elevation data, land-use, coast-line, observations,
and studies, the methodology was applied and the inundation maps for three different event was estimated. The results
were compared historical data and other estimates, verifying the general validity of the method.
