Report ties gas output to US quakes

2012-04-07 19:32

New York - A federal report says oil and gas production may explain a sharp increase in earthquakes in the Midwestern region of the US.

The researchers found the rate of quakes has jumped six-fold from the late 20th century through last year, with a particularly sharp rise from 2009 to 2011. That includes mild quakes.

The researchers said the timing and geography suggest some kind of link to oil and gas production, but it's not clear why the two might be related.

Some previous work has linked earthquakes to injecting huge amounts of wastewater deep into the earth.

The study from the US Geological Survey has not been published, but it is scheduled to be presented at a scientific meeting later this month.

    The Greens will link anything and use computer models to prove it.

      This is a federal report - the US government not green. People in Pennsylvania were complaining for 5 years about their polluted water before the EPA took note. This is what awaits SA when fracking is given the go-ahead here.

    Frack Off! Earth Rapers!

    Pennsylvania sits on top of an ancient fault line, thus earthquakes are to be expected. And lets remember that correlation does not prove causality. But be that as it may and lets assume it is the drilling and extraction that causes all these quakes. Surely it is an advantage to have the tension building up in the crust relieved early before it builds up and than results in one major earthquake. A hundred small quakes surely do less damage than one big one. And lets remember that the Karroo also sits on a fault line, let's frack.

      Horst Muller: NY Times 11dec2011 report on string of earthquakes in Ohio, Arkansas, Oklahoma and Texas, didn't realise Pennsylvania also had earthquakes from fracking. Cuadrilla's drilling in the UK also caused tremors- it's happened often enough to accept the link. It's silly to tempt/ under-estimate the forces of nature, whether it's an earthquake or tsunami. Are you from Germany/ Holland another country where fracking will not be allowed?

    Poor Bankrupt Americans,they are so desparate to link everything with what they fighting can someone relates the two.I so wish that the world can turn against this country including their CEO Britain!!!!
