Oil and gas 'fracking' wastewater caused 11 earthquakes in Ohio: seismologist
A northeast Ohio well used to dispose of wastewater from oil and gas drilling almost certainly caused a series of 11 minor quakes in the Youngstown area since last spring, a seismologist investigating the quakes said Monday. Injection wells have also been suspected in quakes in Ashtabula in far northeast Ohio, and in Arkansas, Colorado, and Oklahoma, Armbruster said.
So it isn’t the fracking they are blaming, it is the reinjection of waste water, thousands of gallons daily (NOT 600 million litres daily) that they say caused the earthquakes.
But how can that be? This is a big company with big research who said everything would be safe, they knew what they were doing.
“I think we’re comfortable that in today’s society people manage water . . . (and) know how to do it safely,” Izhakoff says.(Toronto Star article, December 31, 2011)
