The deep drilling involved in geothermal power production can induce earthquakes.

Icarus. The Tower of Babel. We all know what can happen when humans reach too high. Well, apparently reaching too low can also have some negative side effects. In mid-August, a geothermal power plant under construction in Germany set off a trembler that registered at 2.7 on the Richter scale. A similar project in Basel, Switzerland, set off successive earthquakes in 2006 and 2007, one registering as high as 3.4. While some seismic activity has always resulted from geothermal installations, a new process which digs deeper and involves fracturing solid rock, rather than harvesting existing steam beds, both promises to increase power production and, evidently, earthquakes. The news is disheartening, considering that a report from the Department of Energy that came out earlier this year cast geothermal energy as real possibility for significantly reducing our reliance on fossil fuels in a relatively short time frame.
