Monitoring surface displacements that occur above storage caverns in salt bodies is important to estimate risks for infrastructure the immediate vicinity. As pressure inside a cavern usually lower than surrounding rock, converges continuously. This volume loss leads prominent subsidence bowl at surface. Often this approximated by linear velocities, However, particular gas caverns, fields of multiple close proximity can cause displacement which are spatio-temporally complex. The amount...
Time series of interferometric SAR (InSAR) images offer the potential to detect and monitor surface displacements with high spatial temporal resolution, even for small slow deformation processes. Yet, due nature InSAR, signal can contain a multitude contributions. Different displacement source mechanisms could superpose each other, signals that are residuals atmospheric topographic effects not be completely removed during processing time or non-coherent noise exist. Therefore, criteria...
<p>Crustal earthquakes are events of sudden stress release throug­h rock failure, for example as a consequence continuous and long-term buildup at tectonic faults that eventually exceeds the strength rock. Before under increasing fault, surrounding crust is slowly deforming. The amount pattern crustal deformation carries information about location potential magnitude future earthquakes.</p><p>Time series space-borne interferometric...
