   Annual rates of vertical and horizontal surface displacement modeled from
       InSAR at Redfield Campus for periods ending in 1995 and 2005.
The figure shows similar displacement magnitudes over 10 years but the main production contraction center has
     shifted SW by 500 meters increasing the very small displacements over the campus.     GLO - July 2006

Conceptual Model for Geothermal
                  Regional faults serve
                  as conduits to fluid
                  Fluid flow is episodic
                  and characterized by
                  boiling and mixing
                  with shallower
                  Evidence of boiling
                  front in core indicates
                  proximity to fault
