One-Fifth of All Central and Eastern US Seismicity Tied to Four Oklahoma Disposal Wells

That something strange is going on beneath the central and eastern US is not in doubt.  Since 2008, there has been a remarkable rise in seismicity, a good deal of it attributed to anthropogenic causes.  States like Ohio, Oklahoma, Arkansas, and Texas have all seen significant increases in seismicity.

A new study published in Science suggests that 20% of all central and eastern US seismicity since 2008---one-fifth---can possibly be laid deep at the feet of only four wells. 45% of of all of that seismicity comes from Oklahoma, a state that in 2014 has had more earthquakes than California, which as we've learned, has its own possible problems.
