NPR Reports: Earthquake Rattles Oklahoma; One of Strongest Reported in State:

The epicenter was around 8 miles northwest of Pawnee, a town of less than 3,000 people. Shortly after the large quake hit, at least four additional temblors struck the same area, with the strongest having a magnitude of 3.6; all of them were shallower than the first quake.

According to the National Weather Service's Tulsa office, the earthquake ties the strongest quake in Oklahoma history at 5.6 magnitude. The previous record breaker hit on Nov. 5, 2011, the agency says.

The NPR article included this quote from the US Geological Survey:

"Locations across the central and eastern United States (CEUS) have been experiencing a rapid increase in the number of induced earthquakes over the past 7 years. Since 2009 rates in some areas, such as Oklahoma, have increased by more than an order of magnitude. Scientific studies have linked the majority of this increased activity to wastewater injection in deep disposal wells in several locations. However, other mechanisms such as fluid withdrawal, enhanced oil recovery, or hydraulic fracturing processes can also result in induced earthquakes."

The USGS site included these maps:







I would add: we felt it up here in KC. KMBC 9 posted this seismographic map:

1. Last year I saw an overlay of the fracking waste water injection sites

And the incidence of tremors. It was a shocker.

2. K&R

Land owners do not own the rights to the oil on their land. They've sold those rights to the greedy, oil frackers. It takes a quake near a bushit estate for any bans to be issued. If you live near Dallas, you know what I mean.

3. ??? Many land owners

still own the mineral rights.

[saidsimplesimon]

4. OK, I stand corrected.

Perhaps I am listening to an excuse from those who wish to hide their complicity?

5. In oil country a lot do not own their mineral rights...a lot

It isn't at all uncommon for ground with rights intact to be sold separately at land auctions here. Most land with mineral rights intact are leased to producers..

6. Land developers all of over the U.S. are also

Keeping the mineral rights to developed properties now.
Like entire subdivisions.

7. It depends on what part of the country you are talking about.

In some states the farmers and ranchers have mostly retained mineral rights. Also, they are pretty smart about conditions in the leases.
