The fear of earthquakes is one of the main reasons for reservations about geothermal energy. In order to get hot water from the depths, crevices in the rock underground often have to be created. This is done by injecting large quantities of water under high pressure. The problem is that such hydraulic stimulation is accompanied by vibrations in the underground, known as ''induced seismicity''. A new study from the now points a way that could help to reduce the seismic risk.
