发帖数: 2690 | 1 rise in Midwestern earthquakes probably due to oil and gas production, study
suggests
By Malcolm Ritter, The Associated Press
NEW YORK, N.Y. - A federal report says oil and gas production may explain a
sharp increase in earthquakes in the Midwestern region of the United States.
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 U.S. Geological Survey has not been published, but it is
scheduled to be presented at a scientific meeting later this month. |
