In collaboration with Yosemite National Park, the recent El Capitan

In collaboration with Yosemite National Park, the recent El Capitan rockfalls have been analyzed in detail by the Risk Analysis Group. Assessment of rockfall susceptibility is a difficult task because numerous processes contribute to make the rock mass unstable. The Risk Analysis Group of the Institute of Earth Sciences of the University of Lausanne has been working for several years to improve the forecasting of such events. Since 2010, several PhD students and researchers of the group have worked on rockfalls in Yosemite National Park.
