Why is fracking stopped after a tremor? Think of a reason and then ask why fracking starts again. One naturally thins it's like stopping hitting a pane of glass with a hammer because it has cracked, and then starting to hit it again, hoping it won't shatter completely.
Squirting water into rock under high pressure is bound to cause rock fracturing and tremors in order to release the gas and it's entirely normal. Stopping is merely the natural reaction to assess the volume of gas released along with the status of the borehole, fracture direction and extent of the reservoir, in which case why are all the stoppages reported in the media in the first place?
Well, stoppages have to happen by law at a certain tremor threshold, that being 0.5, which is the government red light system, but that is to mollify ecologists. The fact is that tremors of below 1.5 cannot even be felt at the surface, except by specialist equipment.
Ecological impact aside, the continual reporting of stoppages due to tremors isn't helping public perception unless the reasons for the stoppages are understood and reported too.
