The deadly earthquake that struck Lorca in southern Spain in 2011 killing nine people may have been caused by groundwater extraction, scientists have claimed. A study published in Nature Geoscience said decades of overextraction of groundwater for irrigation and livestock had seen the water table drop around 250m resulting in pressure at the Earth's surface. Satellite data was used to correlate changes to the Earth's crust caused by water extraction to deformities caused by the quake.
