Description:   The microseismic technique was used to monitor the effects of the hydraulic stimulation of a hot dry rock geothermal reservoir. The events, generated by the stimulation during injection, were detected on a 3-dimensional sensor network and processed by an on-line system. The test results indicated the feasibility of using the induced microseismicity to map the growth of the stimulated region. The majority of the detectable seismicity was caused by shear events with a characteristic length of 10m.
