I wonder how close this process is to hydraulic fracturing to extract fossil fuels. Is the volume of liquid pumped into the ground similar? I imagine geothermal is pumping more and deeper to get to where the earth is warmer, but I am not sure.

In my area, Pittsburgh Tristate area (WV,OH,PA) fracking is big business. Seems we are fortunate to not have a major fault line running through the area.

edit - clarifying that I am talking about fracking for fossil fuels

Perhaps this could be thoroughly tested by performing high-pressure hydraulic fracking in very close proximity to gas pipelines.
