Fracking Wastewater Tied by U.S. Scientists to Seismic Activity

Government scientists are focusing on the disposal of wastewater from oil and gas drilling as the possible cause of scores of earthquakes that have shaken the central part of the U.S. since 2000, according to a study.
Researchers think the increased seismic activity may be linked to wastewater injected into the ground by oil and gas drilling operators, William Ellsworth, Earthquake Science Center staff director for the U.S. Geological Survey, said yesterday as he discussed the findings at a conference in San Diego.
