The Rock may be about to star in the earthquake disaster movie San Andreas, but it turns out California is no longer the leading state for quakes. Oklahoma had more than 500 earthquakes of magnitude 3.0 or greater in 2014. Quakes in the Sooner State are now hundreds of times more common than less than a decade ago.
And Oklahoma is not alone. Eight states in the South and Central U.S. are experiencing rapid earthquake growth as a result human activity, according to a new report from the United States Geological Survey (USGS).
