Drought and Irrigation Contribute to Earthquakes

Drought and WaterAn recent article published in the Nature International Weekly Journal of Science says that the recent droughts and our increased reliance on irrigation are removing subsurface mass, causing more earthquakes. Fracking, which pumps water underground vs. removing it from the ground, has long been blamed for creating more earthquakes.  Now Nature.com is saying that removing water is causing the overlying strata to exert less pressure on faults, causing an increase in earthquakes.   It sounds like we should embrace fracking as a nation, if for no other purpose than to replace what irrigation is removing from the freshwater aquifers.
