A seismic network to resolve the response to the 2018 geothermal reservoir stimulation in Espoo/Helsinki, southern Finland

In June and July 2018 the St1 Deep Heat company stimulated an Enhanced Geothermal System at 6.4 km depth below the campus of the Aalto University in Otaniemi, Espoo. I discuss several topics associated with this stimulation experiment including the seismic networks that were deployed to monitor the response to the water injection; properties of the induced seismicity; the public response in the surrounding neighborhoods; and seismic hazard-related aspects. I will give a brief overview of the seismological research questions that can be tackled and the range of established and new analysis techniques that can be applied to the collected data sets.
