Last weekend, a swarm of seven earthquakes in just 14 hours between Saturday evening and Sunday morning in Oklahoma made national headlines.
Those seven quakes were immediately preceded by another earthquake that measured 4.3 on the Richter scale in Langston, OK, which struck at noon on Saturday. And on Monday, a quake that measuring 3.9 hit just northeast of Harrah, OK, followed in the same region just hours later by a 3.8 magnitude earthquake, data from the U.S. Geological Survey shows.
The ground in Oklahoma keeps shaking, and state, federal and independent researchers have pointed to the shale gas rush as the likely culprit for many of the tremors. Some in the state have called for a halt to fracking and wastewater injection. Others are pushing to allow the injections to continue in the hopes that more research will allow scientists to pinpoint what makes individual disposal wells pose greater or lesser risks. MORE
