For centuries, the region around the Eger Basin on the German-Czech border has been affected by swarms of small earthquakes that occur in episodes and can last for months. In addition, carbon dioxide and thermal water often rise to the surface there.
Young volcanism and the presence of minerals and ores indicate magmatic processes in the lower crust. The interplay between magmatism, earthquake swarms, carbon dioxide and mineral springs has not yet been clarified. We want to investigate these underground processes more precisely with a large-scale seismological experiment.
We are installing around 300 seismic stations over an area of 100×100 km for 12 to 18 months. These instruments record ground vibrations caused by weather or earthquake swarms. No active seismic sources are used.
The instruments are provided by the Geophysical Instrument Pool Potsdam (GIPP) of the GFZ.
