Expert seismic monitoring is required when it comes to evaluating the seismic reaction of the subsoil to the intervention associated with a deep geothermal energy project, and to taking any appropriate measures to minimize this reaction. GEOBEST-CH has a pool of surface and borehole seismometers that the SED can use to provide active support on selected projects in this important task. This enables the SED to contribute its expertise and experience in the areas of network planning and operation, real-time seismic analysis, and automatic notification of the relevant authorities and stakeholder groups in an optimal manner, and without significant additional costs for the cantons or operators. At the same time, it also makes it possible to avoid insufficient seismic monitoring due to cost pressure or lack of competence.
