Fracking-Linked Earthquakes May Strike Far from Wells

ANCHORAGE, Alaska — Fracking may cause earthquakes much farther from the sites of its wastewater wells than previously thought, researchers said here Friday (May 2) at the annual meeting of the Seismological Society of America. In central Oklahoma, a cluster of four high-volume wastewater injection wells triggered quakes up to 30 miles (about 50 kilometers) away, said lead study author Katie Keranen, a geophysicist at Cornell University in New York. The earthquakes have since spread farther outward, as fluids migrate farther from the massive injection wells, she said. “The pressure is high enough from the injected fluids to trigger earthquakes.”
