Drilling waste disposal risks another damaging Okla. quake, scientist warns
SAN DIEGO -- Oklahoma officials are risking another large earthquake like the one last November if they continue to allow oil and gas companies to inject waste near the same fault, said a seismologist who has studied the magnitude-5.6 earthquake.
Recent tremors in drilling areas are too small to count in nuclear risk assessments, NRC official says
A multiyear review of earthquake hazards at U.S. nuclear plants ordered after Japan's Fukushima Daiichi disaster will not include data from recent earthquakes that may have been triggered by underground wastewater injection from shale gas and oil wells, a Nuclear Regulatory Commission official said. The quakes in question are typically too small to affect the analysis, said Yong Li, senior geophysicist in NRC's Office of Nuclear Reactor Regulation.
