The occurrence of subsidence, landslides and volcano unrest, as well as liquid and gas reservoir changes are observed by remote sensing data and validated by ground truth. The detection of such crustal deformation occurrence allows uncovering spatial and temporal patterns of subsurface processes such as fault slip, strain and stress field changes, reservoir pressurization and drainage, and feedback mechanisms.
Besides the source of deformation, also rheology, temporal and mechanical behavior of the surrounding rocks, effects of fault and heterogeneity complexities and interactions of sources, loading types and the topography are in the focus of this session.
In this session we are seeking contributions from geodetic, structural geology and modeling community to analyze and interpret observations from microwave and optical sensors, including InSAR time series, high rate GPS, far field and near field photogrammetry, UAV observations and image correlation methods.
Emphasizis on errors sources, contamination and correction procedures is welcome. Analytical and numerical inverse and forward modeling strategies and model deficiencies ideally contribute to process understanding, and eventually allow assessment of natural hazards and human induced deformation.
Therefore, the aim of this session is to bring together researchers from different communities working at different scales of crustal deformation processes. We welcome contributions from tectonics, volcanology, geodynamics, geodetic and natural hazards community.
