In recent years, the SED has been able to assist several Swiss deep geothermal energy projects in seismic monitoring, thus initiating a constructive dialogue with operators and cantonal authorities. Based on this experience, the SED has developed first recommendations for cantonal licensing and enforcement authorities on how to deal with the problem of induced seismicity in different phases of a deep geothermal project. However, these recommendations are based on experiences from only a few well-documented projects. The practical experience with their implementation has been largely missing in Switzerland so far. It is therefore difficult to predict how well these recommendations will be applicable in the local context (geological, political, cultural) and what adjustments may need to be made. Another important issue in this context is how guidelines and regulations from other technical or regulatory areas interact and are compatible with seismological recommendations for avoiding induced seismicity. Frequently, conflicts can only be identified and solved in the practical implementation of projects and through the close cooperation of the seismologist with approval authorities and operators. Equally important is the regular review and adaptation of all relevant policies and regulations based on the growing knowledge and experience. Whenever possible, this should be done in consensus with all stakeholders. In the project Geobest, the SED will continue to collect, evaluate and interpret basic data sets on the development of induced seismicity in deep geothermal projects in high quality and resolution. In addition, the SED can provide seismological advice and support to the cantonal and federal authorities in their licensing and monitoring obligations in all phases of a deep geothermal project. In this way, the SED wants to contribute to creating equal assessment standards for the environmental impact assessment across cantonal borders and, in the short to medium term, to standardize and thus considerably simplify and accelerate this process. A central website should inform the public independently, up-to-date and professionally on the subject of induced seismicity in order to support a substantive discussion of all interest groups. |
