 KE,US,
The lakes along the Great African Rift Valley are among the largest fresh water lakes in the world. They lie in depressions created by slow stretching and thinning of the east African continent over millions of years. Many of the essential geological structures that enable the continent to tear and produce earthquakes are hidden within

Another Texas earthquake whack-a-mole

As we recall in our continuing saga, Texas allows saltwater injection, and has never had earthquakes with this.  But, greed being what it is, the injectors are tempted by the Fruits of Satan, which in this case means gas-frack waste.  They mix it in and are shocked, shocked to get earthquakes.  Then it takes forever for them to secretly own up, and you get a big mess, like up in Dallas.

Oklahoma Kept Silent About Fracking To Protect Industry

While it has long been known that 'fracking' byproducts and waste water well injections can and do cause earthquakes, it seems that in Oklahoma, that fact was suppressed to protect the oil industry. According to an article on Rawstory, University of Oklahoma President David Boren pressured subordinates to either downplay or remain silent on the issue after being pressured by oil executives.Waste water well injections pump millions of gallons of chemical-laden liquid into 'waste water [...]

And again it’s almost the start of a weekend! I collected some nice links for you, I hope you like them. Today is Friday and here are your links! The recent Mw 6.0 Wilberforce earthquake in New Zealand has generated a set of landslides. And by writing a set, I mean over 2000. Read this post on a report on all the landslides.   Over 3600 earthquakes have been recorded in Oklahoma since 2009. A recent study finds out that preexisting faults

People should know that not all earthquakes are the same.  Some earthquakes of larger magnitudes do not produce such an intensity.  This was obviously a shallow thrust, and the town of Anthony was in the hammer zone.  Nobody can take a lot of these without the house falling apart. In the Tulsa World article, it was pointed out that the insurance companies may never pay.  I'm saying they

Ah, a few more injection wells put on 'Yellow Light'.  I wonder if they are really going to keep up this closing business as the 4's come in fast and furious. Look at that felt area! Oblique normal along the NE megathrust. That whole upper zone is totally disorganized, and still able to pop off these 4+ earthquakes.  I have high hopes if they forget their little restrictions on

M4.0 earthquakes start to shut wells in Oklahoma

Article Wow, and I thought they would get to 5's at least.  The earthquake mechanism has advanced to the point where 4's are an every-day occurrence.  I didn't think they would take action on those.  That would explain why earthquakes have moved further north.  They might not be shutting down a lot of wells, but nobody is going to inject frack waste where there has been an M4.  These

I told you it would happen again.  The idiot son decides to mix in surface water (fracking waste) into the salt water injection well, and we get another series of earthquakes. Right now these are poorly located.  They should be right on top of each other.  This is a fine game of Whack-a-Mole, and let's see how big we get.  :) **Remember, if anybody in Texas were honest we'd know how
