As a geologist, I often get questions about fracking. In Oklahoma, many small earthquakes have plagued residents and kept them on edge wondering why the sudden surge in seismicity. One of the large quakes has been linked to wastewater fluid injection (not fracking) and this inadvertant release of stress may have stressed another area leading…

November 5 was the anniversary of the largest earthquake recorded in Oklahoma in 2011. But the quakes aren’t done. OK has experienced a rash of small and moderate quakes that create booming noises, leaving residents edgy. Many Oklahoma earthquakes make a ‘boom’ sound | KFOR.com. There was a lot of talk this weekend about those…

Can we create earthquakes? Just add water.

This is a fascinating piece that helps us better understand the effect humans (we mere humans) can have when we utilize the power of water in a particular way. It’s not a good outcome but it’s very interesting. Can we cause earthquakes? Yes, we certainly can. Wastewater injection spurred biggest earthquake yet, says study: 2011…

Debate on fracking: Science second to emotion

DNlogo

Another topic where emotions get the best of both sides, fracking. When this happens, science is used as a weapon, not a tool. Doctors, scientists say fracking critics misrepresent some facts to make their point In the debate over natural gas drilling, the companies are often the ones accused of twisting the facts. But scientists…

Fracking: It’s a bit more complicated than that, scientists say

DNlogo

Fracking is a controversial topic that has generated some heated emotions among skeptics. For example, when Brian Dunning aired a Skeptoid episode on the topic, he lost many subscribers because he did not come out and say it was an all around horrible thing. Big issues are typically more complicated than the black and white…

Photo alleging cancerous deer related to fracking is false

cancerousdeer

Snopes.com: Cancerous Deer. A friend “shared” this photo on Facebook. It was accompanied by the following text: Cancerous deer shot in Dimock PA. Lived near a stream where fracturing water had been said to be leaking. Is fracking really “safe” for us? EPA’s testing of water in Dimock found several carcinogenic and neurotoxic drilling chemicals…

First evidence that fracking causes earthquakes, but don’t get all shaken up

U.K. Quakes Likely Caused by Fracking One nagging question about the fracking process to extract natural gas and oil has been: Does this process cause microearthquakes in the area? This is actually a complicated explanation. Fluid injection and similar changes to hydrogeologic regimes have caused earthquakes. A new report links fracking specifically with earthquakes that…
