Title: | Post-seismic stress relaxation with a linear transient rheology | Journal: | Annals of Geophysics | Series/Report no.: | 2/53 (2010) | Issue Date: | Apr-2010 | DOI: | 10.4401/ag-4642 | Keywords: | Transient rheology Geodynamics Stress tensor Coulomb failure function Post-seismic relaxation |
Subject Classification: | 04. Solid Earth::04.07. Tectonophysics::04.07.99. General or miscellaneous | Abstract: | We performed an analysis of post-seismic stress relaxation, taking into account generalized linear rheologies. We compared the stress field (and its derived functions) obtained with a classical Maxwell rheology with that obtained with a transient Burgers body. From a set of synthetic case studies, we have revealed quantitative and qualitative differences both in relaxation times and in local stress values when a transient rheology is introduced. As a practical application, we modeled the time evolution of the Coulomb failure function following the 2009 L'Aquila earthquake, and we show that a transient rheology can lead to non-monotonic time dependence. |
