Enhanced geothermal systems (EGS) are an attractive source of low-carbon electricity and heating. Consequently, a number of tests of this technology have been made during the past couple of decades, and various projects are being planned or under development. EGS work by the injection of fluid into deep boreholes to increase permeability and hence allow the circulation and heating of fluid through a geothermal reservoir. Permeability is irreversibly increased by the generation of… 
Developing subsurface energy exploitation strategies by considering seismic risk
The injection or extraction of fluids in the subsurface for energy purposes (e.g. geothermal exploitation, CO2 storage or geological energy storage) requires both the operation efficiency and the
A risk-mitigation approach to the management of induced seismicity
TLDR
The more rational approach proposed herein is based on applying the same risk quantification and mitigation measures that are applied to the hazard from natural seismicity, which allows informed decision-making regarding the conduct of anthropogenic activities that may cause earthquakes.
A risk-based approach for managing hydraulic fracturing–induced seismicity
TLDR
A risk-informed strategy for choosing red-light thresholds that require immediate well shut-in and a guideline for traffic light protocols and managing induced seismicity risks are developed for hydraulic fracturing of the Eagle Ford shale in southern Texas.
A novel approach to assessing nuisance risk from seismicity induced by UK shale gas development, with implications for future policy design
Abstract. We propose a novel framework for assessing the risk associated with seismicity induced by hydraulic fracturing, which has been a notable source of recent public concern. The framework

Value at Induced Risk: Injection‐Induced Seismic Risk From Low‐Probability, High‐Impact Events
The increasing number of damaging earthquakes, induced by underground injection of fluids, demonstrates the need of a structured methodology for critical thinking about and clear communication of
Developing an Application‐Specific Ground‐Motion Model for Induced Seismicity
Abstract A key element of quantifying both the hazard and risk due to induced earthquakes is a suite of appropriate ground‐motion prediction equations (GMPEs) that encompass the possible shaking
A Probabilistic Model to Evaluate Options for Mitigating Induced Seismic Risk
Common responses to induced seismicity are based on control of the anthropogenic activity causing the earthquakes, such as fluid injection or withdrawal, in order to limit either the magnitudes of
