In a new study, scientists from the Remote Sensing and Image Analysis and Engineering Geology working group at TU Darmstadt have published a paper dealing with ground movements in Hesse. The research results provide important insights and contribute to a better understanding of the measurement of ground movements using remote sensing.

Ground movements are a significant phenomenon that can have both natural and human causes. In cities, they are particularly relevant as they can affect buildings and infrastructure. In the past, ground movement data from remote sensing has often only been accessible to experts. Thanks to the Ground Motion Service Germany (BBD) published in 2019, the general public and decision-makers can now also view this data.

The researchers used Persistent Scatterer Interferometry data from the Ground Movement Service Germany to analyse ground movement patterns in Hessian cities. They identified regions with significant ground movement. Two case studies are particularly noteworthy:

• Frankfurt am Main: Here, subsidence was evident in the city. This was probably caused by groundwater extraction during the construction of various buildings.
• Crumstadt in the northern Upper Rhine Graben: Pronounced seasonal fluctuations were detected in this region. These could be due to activities in a nearby underground deposit.

The study emphasises the need to include external factors such as weather data in the analysis in order to gain a comprehensive understanding of the climate-related causes of ground movements. This is crucial in order to take preventative measures and minimise the impact on buildings and infrastructure.
