Fracked-Off: Gas Extraction 'Causes Quakes'

A new technique to extract lucrative hard-to-reach natural gas is causing earthquakes across Middle America, literally.
Hydraulic fracking - pounding streams of high pressure water and chemicals into rock formations to loosen gas deposits - has been hailed as a solution to the US's dependence on foreign petroleum. But residents of Ohio and other states worry the technology is moving the earth beneath them.
Susie Beiersdorfer was sitting in a deli in Youngstown, Ohio, on New Year's Eve, when she felt the 4.0 magnitude quake which made headlines across the US. "It felt like a truck hitting the side of a building," Beiersdorfer, a geologist who used to work in the energy industry, told Al Jazeera.
While this quake was one of the biggest to be linked to fracking and disposal of waste water from the process, it would not be the last. "They [state authorities] just released information on another quake that happened on January 13," she said.
In early January, the state government - which is responsible for regulating the industry - ordered the shutdown of five wells near Youngstown, after quakes rocked the area.
At least 11 earthquakes have been recorded around Ohio since March, causing controversy for the 177 deep well injection sites in the state which are being pumped full of nearly 37,000 barrels of toxic waste water daily.
