SESSION DESCRIPTION

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 
interdisciplinary 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 surveys as well as 
InSAR measurements are increasingly being used. These geodetic observations monitor the recent 
crustal deformation with high accuracy and thus, provide the possibility to resolve details of 
post-, co- and interseismic deformation signals. Additionally, GPS and InSAR data are used to 
derive complex earthquake related information 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 interdisciplinary 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.
