Lorca earthquake caused by groundwater extraction
October 23 , 2012
Scientists studying the fault beneath Spain’s Lorca city have said the removal of groundwater may have resulted in the deadly 2011 earthquake.
Detailed satellite maps enabled them to detect which parts of the ground had moved.
The scientists’ report in the academic journal, Nature Geoscience, said the shifts correlated with locations where water had been drained for years.
The study highlights how human activity can have a significant influence on seismic effects.
The drainage occurred at a depth of just under 2 miles explains why the Magnitude 5.1 quake caused vast damage.
