I just moved from OKC, IMO fracking increased earthquakes 800 plus % in that area. The big one 5.6 or 5.8 caused damage. Oil companies and state won't admit fracking causes earth quakes if so they most likely would be held responsible for damage to private property. Couse who would guess NATURAL disaster like earth quake not covered on regular insurance policy (thank you Insurance LObbist and state Insurance Commissioner.
My previous home did not have crack in the foundation or structure, but after hundreds of earth quakes they started showing up. IMO oil companies should be held responsible if their methods caused damage 1 mile away or 50. But tax dollars, Lobbist money, oil company profits, Political under the table payoff rule the land whether OK, Kansas, PA ect....
