Many scientists are concerned with fracking — the use of hydraulics to get gas and oil out of the ground — and suggest the practice might be responsible for increased seismic activity. “We call this induced seismicity,” says US Geological Survey Seismologist Lucy Jones. She says earthquakes can be triggered when waste water, used in the hydraulic process is disposed of by injecting the water deep into the...
