Hype for the Future 180D → Nemaha County, Nebraska
Overview Located in the southeastern portion of the State of Nebraska along the Missouri River, Nemaha County is a notable county home to Peru State College and using the City of Auburn as the county seat. The Nemaha Valley Museum is located within the Auburn city limits, along with the Auburn Inn Motel (as well as the extension at Auburn Inn South). Smaller communities, primarily in the form of villages, are also prevalent throughout select portions of the county, including Johnson, Brock, […] -

Time to Start Paying Attention to #Fracking’s #Earthquakes
With wastewater injection sparking swarms of small quakes, some states are taking notice of the danger
by Sarah Zielinski
July 3, 2014"In the new study, Katie M. Keranen, a geophysicist at Cornell University, and colleagues tallied up earthquakes that were part of a swarm that started near Jones, Oklahoma in 2008. This swarm accounts for about a fifth of the recorded quakes in the region, which have increased 40-fold from 2008 to 2013 as compared to 1976 to 2007. The researchers then created a computer model that showed how pressures from nearby injection wells were affecting seismicity.

"Some of the earthquakes have occurred as far as 35 kilometers (21 miles) from the injection wells, much farther away than scientists had previously thought such quakes were possible. They also found that as time passes, the region of increased pressure from those wells continues to grow. If that zone intersects with a large fault, the pressure could set off a larger earthquake.
“The increasing proximity of the earthquake swarm to the #Nemaha fault presents a potential hazard for the #OklahomaCity metropolitan area,” the researchers write. That fault, which runs from Oklahoma City north to Lincoln, Nebraska, is capable of hosting a magnitude-7 #earthquake, they note."
