Destabilizing the precarious equilibrium at depth with geothermal wells may reactivate the geological layers causing earthquakes. Researchers have studied the seismic activity linked to a geothermal drilling in search of supercritical fluids. They discovered that the drilling did not cause uncontrolled seismic activity. This drilling under such critical conditions suggests that the technology is on the verge of mastering geothermal energy, paving the way for new sources of non-polluting heat and electricity.
