WATCH: Exploring the relationship between fracking and earthquakes in Texas


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? Could the chemicals be lubricating the long dormant rock? Is it coincidence? Are there other factors involved like the drought or low aquifer levels in the area. Southern Methodist University is conducting a research project to figure out what’s going on down below.
