Description:   In this study over 5000 cubic metres of viscous fluid was injected in order to create a permeable connection between two of the wells drilled in the Carnmenellis granite.  The induced seismicity was monitored with six sub-surface accelerometers and four hydrophones in the wells.  202 events were located during the eight-hour period of the injection.  They were used to define the area and structure of the stimulated region and to understand the physics of the failure at joints.
