Wastewater cap could dunk Oklahoma quake risk
Rising volume of underground injections had caused seismic activity to skyrocket
THE SHAKES In Oklahoma, disposal of massive amounts of wastewater into underground wells over the last few years (redder-shaded regions) caused an uptick in earthquake activity (gray dots) over historic rates (black dots), including several large quakes registering magnitude 4.5 or stronger (stars).
