Aftershocks continued to be felt for weeks after the event and minor earthquake activity that still continues in the area today may be a continuation of aftershocks.

Opponents say that fracking causes disruption and damage to the environment, including minor earthquakes and the risk of water pollution.

However, the facility continued to be largely unused for many years, and by 2011 it had fallen into disrepair, as well as incurring minor earthquake damage in 2001.

Usually if there are minor earthquakes occurring people assume that will reduce the strain.

There are legitimate fears about fracking: the pollution of groundwater, the escape of methane, the pressure on water resources and the risk of minor earthquakes.
