Abstract (English)

This paper addresses the issue of induced seismicity by Enhanced Geothermal Systems and what this means in terms of its widespread commercial development. EGS promises to bring the potential of energy from geothermal systems to areas that do not have the naturally occurring reservoirs needed to produce heat and power from geothermal sources. There have been cases of individual EGS operations being disrupted by induced seismic events that have caused minor damage or have been felt by the public. The industry has reacted to these concerns and this paper analyses these reactions and assesses whether the seismic risk could be a problem for widespread use of EGS. It concludes that the perception of risk is important alongside the objective assessment of risk and that merely addressing the information gap may not be enough to allay the public concern.
