Geothermal Power and Earthquakes

Swiss earthquakes from geothermal drilling? I had heard the oil and gas drilling could contribute to earthquakes - I believe similar allegations were made in Texas with regard to the Barnett Shale play - but this was the first time I heard of it in connection with drilling for geothermal energy. Geothermal Basel was trying to drill down 3 miles to hit rock, and caused small earthquakes in the process. At least that is what was alleged.

It's further proof of this axiom - there is no free lunch, and no power source without some drawback.
