3.9 Earthquakes Shake Arkansas, Some Doubt ‘Fracking’ Link
GREENBRIER, Ark. — A pair of magnitude-3.9 earthquakes rumbled through central Arkansas this week, about a month after two companies halted operations at nearby injection wells over concerns that they may be linked to the seismic activity plaguing the region.
The latest big quake struck near Greenbrier on Friday morning, less than 24 hours after an equally strong quake hit nearby, according to the U.S. Geological Survey. Officials said no one was hurt and damage was minimal.
