Hydraulic fracturing, where fluids are pumped into the ground at extremely high pressures to crack rocks that release natural gas and oil, has been shown to do just that in certain situations. Increasing the fluid pressure inside the fault partially de-stabilises the friction-lock, lowering the stress threshold necessary to trigger an earthquake just enough for one to occur. Despite the obvious negative effects that humans have on pre...
