Project 6: Dynamic models of the pre-, co- and postseismic processes
Key objective of this project is to model the spatio-temporal evolution of the absolute stress state throughout the seismic cycle by using kinematic (GPS, InSAR) and dynamic data (focal mechanism solutions, aftershock distribution, tectonic regime changes) as model constraints. In particular the project will assess the role of fluids in the seismic cycle. The forward models will address the controversial debate on the key roles of either fluids or of rate and state friction properties in controlling locking patterns and the co- to postseismic kinematic evolution by predicting stress evolution and testing against seismicity distributions, kinematics, and time-dependent changes of seismic structure.
