Geoscientists have known for decades that the injection of fluid can increase pressures within the pores of deep rock formations, pushing faults that are already critically stressed by forces in Earth's crust past the snapping point.

It has long been understood that earthquakes can be induced by impoundment of water in reservoirs, surface and underground mining, withdrawal of fluids and gas from the subsurface, and injection of fluids into underground formations.

Jointly led by Durham and Newcastle Universities, UK, the research looked at reducing the risk of reactivating geological faults by fluid injection in boreholes.

Since the 1960s, geologists have recognized that fluid injection can induce earthquakes by raising the hydraulic pressure along a fault, pushing the two sides apart to let the crust slide along it.

In a 2000 case that wasn't caused by injection but brought important lessons about how fluids could move underground, hydrogeologists concluded that bacteria - polluted water migrated horizontally underground for several thousand feet in just 26 hours, contaminating a drinking water well in Walkerton, Ontario, and sickening thousands of residents.

In work that offers insight into the magnitude of the hazards posed by earthquake faults in general, seismologists have developed a model to determine the size of an earthquake that could be triggered by the underground injection of fluids produced as a by - product of hydraulic fracturing.
