A recent study conducted by seismologists and geologists has proved that there is a strong positive correlation between waste-water wells and quakes. In the past three years alone, earthquakes in the U.S. have become five times more common than in previous years.

According to the report, more than 300 significant earthquakes, ones above magnitude 3, occurred nationwide from 2010 to 2012, a rate of about 100 a year compared with a past average of 21 per year.

The risk of earthquake occurrence is increased by dumping of left over fluids from shallow hydraulic fracking (fracturing) wells which surge U.S. natural gas production into mile-deep waste water disposal wells.
