It is believed that fracking could have contributed to these earthquakes but the exact mechanism is still poorly understood.
A recent study found that methane from hydraulic fracking sites can flow to abandoned wells.
Scientists have taken a closer look, and found that energy companies used nearly 250 billion gallons of water to extract shale gas and oil from hydraulically fractured wells in the United States between 2005 and 2014.
Natural gas mining could cause issues for human health. It turns out that endocrine disruptors from these activities could potentially harm human development and reproduction.
It turns out that hydraulic fracturing, known commonly as fracking, may be triggering earthquakes. Scientists have found that fracking caused a series of small earthquakes in 2013 on a previously unmapped fault in Harrison County, Ohio.
Scientists have found that the oil and gas extraction method known and hydraulic fracturing may contribute more pollutants to groundwater than previous research has suggested.
Scientists have found that chemicals used in fracking can disrupt not only the human body's reproductive hormones, but also the glucocorticoid and thyroid hormone receptors, which are necessary to maintain good health.
A team of scientists has launched a study of seismic activity in North Texas to determine if fracking may be the cause of a series of earthquakes that have rattled two towns in the region since November.
