Statistical analysis of rockfall volume distributions: Implications for rockfall dynamics [PDF]
Journal of Geophysical Research: Solid Earth, 2003 We analyze the volume distribution of natural rockfalls on different geological settings (i.e., calcareous cliffs in the French Alps, Grenoble area, and granite Yosemite cliffs, California Sierra) and different volume ranges (i.e., regional and worldwide catalogs).

Three-dimensional rockfall shape back analysis: methods and implications [PDF]
Natural Hazards and Earth System Sciences, 2019 Rockfall is a complex natural process that can present risks to the effective operation of infrastructure in mountainous terrain. Remote sensing tools and techniques are rapidly becoming the state of the practice in the characterization, monitoring and ...

Repetitive Rockfall Trajectory Testing [PDF]
Geosciences, 2018 Numerical simulations of rockfall trajectories are a standard procedure for evaluating rockfall hazards. For these simulations, corresponding software codes must be calibrated and evaluated based on field data. This study addresses methods of repeatable rockfall tests, and investigates whether it is possible to produce traceable and statistically ...

Modeling the effect of rockfall on forest development in a dynamic forest landscape model
Ecosphere, 2022 Mountain forests below rocky cliffs are regularly impacted by falling blocks. Rockfall thus increases tree mortality and can locally alter the forest structure.

Time series radar observations of a growing lava dome. [PDF]
, 2008 Exogenous growth of Peléean lava domes involves the addition of lava from a central summit vent and mass wasting on the flanks as rockfalls and pyroclastic flows.

Rockfall Zoning Based on Rockfall Trajectory in GIS Case: Haraz road (Emamzadeh Ali) – Amol [PDF]
جغرافیا و توسعه, 2013 In this paper, Geographic information system (GIS) modeling is used in combination with three-dimensional (3D) rockfall process modeling to assess rockfall hazards. The 3D rockfall model considers dynamic processes on a cell plane basis.

Evaluating earthquake-induced rockfall hazard near the Dead Sea Transform [PDF]
Natural Hazards and Earth System Sciences, 2019 We address an approach for rockfall hazard evaluation where the study area resides below a cliff in an a priori exposure to rockfall hazard, but no historical documentation of rockfall events is available and hence important rockfall hazard parameters ...
