New maps released by the U.S. Geological Survey reveal that seven million people are now living in areas at high risk for earthquakes. Not naturally occurring earthquakes but man-made – induced by oil and gas operations that pump wastewater deep underneath the ground. Parts of Oklahoma and Texas are at highest risk. Last year Oklahoma had more than 900 quakes, up from 3 in 2007. But homeowners have few options when they try to recoup damages from insurance companies or the oil and gas industry.
