Rockfall Research: A Bibliometric Analysis and Future Trends
Géosciences, 2020 Rockfall is one of the main phenomena in mountainous environments due to its fast and high speed of movement, its unpredictability, and, therefore, the difficulty of identifying signs of instability and detachment of the blocks.

Scandinavian Journal of Psychology, Volume 67, Issue 1, Page 115-128, February 2026.ABSTRACT This study explores how Norwegian leaders in rural municipalities attend to disaster risk governance and prepare for resilient response to threats from systemic, interconnected, and cascading hazards. Systemic risk management in the Norwegian municipalities will depend on the context and how critical organizational processes are managed by the

Study on the method of estimating the volume of fragmental rockfall based on image recognition
Shuiwen dizhi gongcheng dizhiThere are frequent cataclastic rockfall disasters in southwest mountainous areas. To accurately simulate the process of rockfall movement and quantify the risk of rockfall, it must first determine the volume of rockfall.

Journal of Geophysical Research: Earth Surface, 2018 AbstractExtremely energetic rockfalls (EERs) are defined here as rockfalls for which a combination of both large volume and free fall height of hundreds of meters results in energy larger than about 80 GJ released in a short time. Examples include several events worldwide.

Rockfall hazard and risk assessments along roads at a regional scale: example in Swiss Alps [PDF]
, 2012 Unlike fragmental rockfall runout assessments, there are only few robust methods to quantify rock-mass-failure susceptibilities at regional scale. A detailed slope angle analysis of recent Digital Elevation Models (DEM) can be used to detect potential ...
