Abstract
The stress field at the source of microearthquake in the interior of the hot dry rock geothermal reservoir at Fenton Hill appears to be different to the far field stress outside the reservoir. The stress field seems to be reoriented prior to failure, during the course of processes that inflate the reservoir.
