Induced seismicity in EGS: Observations and triggering mechanisms
Induced seismicity is typically observed in enhanced geothermal systems (EGSs), especially during and after the operations of rock hydraulic stimulation but also during fluid circulation. Although this seismicity has generally been of low intensity, it has often reached a magnitude large enough to be felt by local inhabitants and cause damage, which has jeopardized the widespread deployment of this technology. In this chapter, we review some of the most relevant cases of induced seismicity in EGS and analyze the physical mechanisms that may lead to rock failure and, therefore, to the activation of earthquakes. Afterwards, we discuss the theories and approaches that have been used to model and forecast such seismicity.

| Summary: | Induced seismicity is typically observed in enhanced geothermal systems (EGSs), especially during and after the operations of rock hydraulic stimulation but also during fluid circulation. Although this seismicity has generally been of low intensity, it has often reached a magnitude large enough to be felt by local inhabitants and cause damage, which has jeopardized the widespread deployment of this technology. In this chapter, we review some of the most relevant cases of induced seismicity in EGS and analyze the physical mechanisms that may lead to rock failure and, therefore, to the activation of earthquakes.
