The Geothermal Engineering Integrating Mitigation of Induced Seismicity in Reservoir GEISER project worked specifically on developing a better understanding of the key parameters that control induced seismicity in response to an injection. The GEISER research team analysed series of past stimulation experiments from projects such as Soultz-sous-Forêts (France), Basel (Switzerland), Berlín (El Salvador), Gross Schönebeck (Germany) and several Icelandic fields.
For the first time, ground motion prediction equations have been derived specifically for geothermal sites and
a comprehensive framework for the assessment of seismic hazard and risk was developed. GEISER also provides guidelines for safe and reliable EGS operation. Key is a dynamic-forewarning-advanced traffic light system that can be used in all phases of a project.
A strategy is proposed to enhance public support for EGS projects. Special attention has to be paid to risk perception. Nuisance and trivial damage should be addressed with care and considered as a significant projects risk.
