Earthquakes
The HDR project in Basel, Switzerland was suspended after causing an
earthquake. On 8 December 2006, only 8 days after water injection started, a
quake occurred measuring 3.4 on the Richter Scale with the epicentre at the
bottom of the HDR borehole. The tremor prompted over 1000 calls to emergency
services by local residents[1] [2], and caused minor structural damage to
several buildings. Water injection was immediately stopped, but minor quakes
continued. Further significant tremors were recorded on 6 January (measuring
3.1)[3] and 16 January 2007 (3.2). Basel is in a known earthquake zone, see
Basel earthquake.
