There have been a notable increase in earthquakes in areas with fracking and injection wells. "TechKnow" traveled to two small neighboring towns in Texas - Reno and Azle - where they had a couple of hits late in 2013 and hundreds of smaller jolts. Something completely unheard of until recently.
Researchers are trying to figure out if there is a connection to the injection wells and the earthquakes. Is the pressure from the injection process re-awakening deep and ancient faults?
