Quantitative Fracture Model for Initiation of Submarine Landslides

Abstract

My long term goals are to develop, test, and clearly present new quantitative methods for evaluating stresses in the earth's crust and to contribute to a better understanding of geologic fracture phenomena, especially faulting, landsliding, joint formation, and dike intrusion. The main scientific objectives of this project are to identify and better understand the factors controlling where submarine landslide failure surfaces nucleate, how they propagate, how deformation accumulates in the incipient stages of landsliding, and to develop methods for analyzing these phenomena. A second objective is to reconcile predictions of fracture mechanics theory with observations of secondary fractures around faults. The landslide and faulting studies are linked because they both involve shear fracture, albeit under quite different environmental conditions. The work also is undertaken with the objective of developing my graduate students as well-grounded research scientists.
