Geodetic observations such as satellite Interferometric SAR (InSAR) data or GNSS measurement allow us to remotely detect large coverage of Earth’s surface deformation associated with various phenomena including earthquakes, volcanic activity, and landslide movements. The satellite-based methods have some advantages for measuring land deformation in that their data are inexpensive to obtain for processing, and the results can provide more details about the spatial scattering of deformed zones of land.
