Objectives
The Task 2 of the project aims at producing dynamic rupture and earthquake cycle models that incorporate generic fault properties constrained by empirical data currently available and developed in Task 1. This requests to change the paradigm of the rupture models, to make faults being 3D features and not 2D zones as commonly done, and having inhomogeneous and anisotropic characters that evolve depending on both their overall and along-strike maturity –not static and homogeneous properties as commonly done. To model the fault property changes with overall and local maturity, new mathematical formalisms have to be implemented.
