Abstract

Slow evolution punctuated by burst like events localized onto interfaces or interface zones control the evolution of a wide variety of geological systems, such as glaciers, earthquakes, rock falls, and landslides. In Earth subsurface and cryosphere, the build-up of energy drives rocks and ice towards critical points at which a small perturbation can trigger a rapid release of energy. We propose a physics-based modelling approach to the development of a better theoretical understanding of the friction and fracture processes that control burst-like dynamics leading to these geohazards, and the construction of numerical models with potential predictive capability that utilize this advance in understanding.

News

This year, the American Geophysical Union (AGU) has added Francois Renard to its roster of distinguished honorees. Renard, who leads the CAS project 'Friction and Fracture and the Onset of Geohazards (FricFrac)' together with Anders Malthe Sørensen, was recognized for his pivotal contributions to experimental and theoretical geophysics and geochemistry.
