Joint Remote Sensing, Ground-based, Seismological monitoring
Key challenges in a nutshell
- Joint interpretation of remote sensing with ground-based data.
- Small displacement (<<1cm/year) requires specific reflectors and benchmarking
Short description of the technology
Imaging the surface deformation through remote InSAR (Radar Interferometry) analysis, possibly supported by ground-based InSAR or LiDAR measurements, Geodetic studies using benchmarks.
State of the Art: technology in existing gravitational wave detectors / TRL
InSAR and geodetic (Total Station, LiDAR, ground-based InSAR) technologies are widely used for small surface deformation monitoring; Remote Sensing InSAR studies being supported by Corner Reflectors. A local seismic network helps locate sub-surface (seismic) sources of ground deformation.
Intended use in the frame of the Einstein Telescope
Surveying any naturally or human-induced surface deformation before, during and after the ET installation.
Improvements needed: Technological challenge for the Einstein Telescope
Full integration of remote sensing, ground-based (geodetic, using geomatics) and seismological approaches and related outputs. A major challenge is related to the expected very small permanent displacements (<< 1 cm / year, mainly vertical) related to deeper natural and near-surface anthropogenic deformation sources. Therefore, remote sensing InSAR needs to be supported by the installation of corner reflectors, benchmarks have to be installed and located with geodetic instruments (using Total Station, UAV image collection and 3D reconstruction, Laser Scanners, regular DGPS surveys), with focus on fault zones.
Economic perspectives of participation beyond the ET applications
