Regulation Limiting Injection Wells Has Decreased Earthquakes In Oklahoma

The rate of earthquakes in Oklahoma has dropped dramatically since late May, when the state limited wastewater injections into energy wells, an Associated Press statistical analysis shows. And a new scientific study says the state is on its way back to calmer times that prevailed before a huge jump in man-made quakes. For quake-prone parts of Oklahoma, the state ordered what is essentially a 40 per cent reduction in injection of the saltwater that scientists generally blame for the massive increase in earthquakes.
