This session aims to bring together scientists working on crustal faulting and deformation processes using InSAR methodologies. The detection of crustal deformation allows uncovering spatial and temporal patterns of subsurface processes such as fault slip, occurrence of land subsidence, magma intrusions and volcano activity, as well as liquid and gas reservoir changes. InSAR allows long-year measurements of tectonic processes at unprecedented and steadily improving spatial and temporal resolution. Recent advances of InSAR techniques and combinations with independent ground truth data permit through inversions indirect source quantification and theoretical and conceptual model developments.

Due to improved satellites and higher resolution processing, especially rheologic characteristics, fault complexities and dislocation distribution, and the distinction of elastic, time-dependent and inelastic (faulting) processes can be investigated. Digital signal processing inspires more sophisticated interpretation of these long time-series, and quantifying the underlying processes with the far field goal to provide new tools for the assessment of natural hazard.

The fundamental goal of using InSAR is advancing our understanding of crustal faulting and deformation processes, hence in specific this session highlights but is not limited to:
- InSAR time series methods
- Errors sources, contamination and correction procedures
- Analytical and numerical inverse and forward modelling strategies and model deficiencies
- Joint or hybrid combination of InSAR data with independent data (GPS, levelling, or gravity) and detailed observations from tectonics and geology
- The use of InSAR for monitoring natural hazards

This co-organized session provides a forum for interdisciplinary discussions. We hope to stimulate interest in the method application and discuss new ways of data handling and processing. Moreover we highlight the application of InSAR in the broad field of tectonics and structural geology and emphasize modelling strategies and result interpretations.
