A review by the Ohio Government in the United States says several small earthquakes in the region last year were probably caused by fracking.
The Ohio Department of Natural Resources, which regulates the oil and gas industry, said  ”A number of coincidental circumstances appear to make a compelling argument that the Youngstown earthquakes were induced.”
According to report the sites in question were used to dispose of fracking wastewater near a fault line, culminating in a 4.0 magnitude quake  after a series of earthquakes were recorded in the region last year.
There’s no shortage of controversy about the effects of fracking, but can the activity really cause something as big as an earthquake? Is there enough information to move forward with the process or is more research necessary?
