South Africa is on the move - researchers make unexpected discovery
South Africa rises continuously - a process that is several millimeters annually. A research team from the University of Bonn has now gained new insights into this phenomenon, which has long been interpreted as a geological appearance. Data from a network of stationary GPS stations collected between 2012 and 2020 show an average increase of six millimeters.
It was assumed that the elevation is caused by geological processes, in particular by a coat plum under the south of Africa. This heated material current was considered the main cause of the land survey. However, the new study results indicate that the phenomenon is also favored by the loss of ground and surface water. This knowledge could have significant consequences for our understanding of the earth's surface in the region.connection between drought and land survey
The study has shown that the earth rises more when water resources decrease. This was compared to a foam ball: if the pressure, depicted by water, is reduced, the ball stretches, which is like the increase in the earth's crust. Through the analysis of regional precipitation patterns, the research team has come to the conclusion that increased elevation can be observed in particular after drought. Satellite data of the "Grace" mission supports this result by illustrating the connection between water loss and land survey.
future prospects and climatic factors
The GNSS network in South Africa offers the opportunity to monitor the phenomena provided over time. In view of the changes in precipitation patterns caused by climate change, this could gain in importance in the future. The research results are not only relevant for the scientific community, but could also support political decision -makers in taking measures in good time in order to mitigate the negative effects of drought and water shortages.
In summary, it can be said that the knowledge of the study not only enables a better understanding of geophysical processes, but also offer important information for coping with future climatic challenges in South Africa. This knowledge could be crucial to develop measures that benefit the water resources and the stability of the region.
