  Information - GD08 Modelling and Monitoring the Deformation and State of Stress of the Lithosphere (co-sponsored by the International Lithosphere Program Task Force VII, co-listed in SM & G)

Event Information
The main goal of this session is to bring together researchers with a focus on monitoring and modelling of the deformation and stress field of the lithosphere. The emphasis will be on synthesis rather than technical advances in modelling techniques and data analysis. Numerical and analogue modelling provide new insights into geodynamic processes such as earthquake cycles, plate tectonics, basin evolution, and mantle convection. To constrain such models, GPS data from continuously observing networks and campaign measurements as well as InSAR surveys provide powerful constraints. These geodetic observations monitor the recent crustal deformation with high accuracy and thus, provide the possibility to resolve the deformation signal into post-, co- and interseismic parts. Additionally, GPS and InSAR data reveal new details of earthquake related processes such as co-seismic slip distribution, post-seismic stress relaxation, poroelastic rebound, afterslip, and silent earthquakes.
The geodetic observations can be related to the physical and rheological properties of the lithosphere by means of modelling. Particular interest is on research which compares and/or combines geodetic observations with data from other sources (e.g. seismology, paleoseismology, structural geology). Contributions may regard, but are not limited to, studies of: 1.) Integrated interpretation and modelling of stress and strain observations; 2.) Finite geologic strain versus geodetic strain; 3.) Relationship between crustal deformation and heat flow; 4.) Mechanical anisotropy of the lithosphere; 5.) Correlation between plate motions, mantle flow, seismic anisotropy, stress directions and plate boundary forces.
