Earthquakes are not caused by fracking!
Recently had several studies done here in DFW area because of this very
topic. We had over 30 tremors with 40 days... Fracking is a 2 - 5 day
event at a well to fracture the shale at the level where they are
extracting oil and/or gas. Most of these happen deeper than those wells.
It is possibly related to injection wells as was likely the causes here.
Either way there has to be a fault that slips to create the quake. 4.5 is
noticable quake. You can feel a 2.5 - 3.2 feels like the house got bumped.
