Nothing like being snowed in to pump away at the keyboard. I brought my Linux laptop to Montreal. It is an old Asus which my son abandoned for a new super-slim one running Win. He's addicted to monstrous Excel spreadsheets to solve everything, and needs the latest. To me, this laptop is practically new and runs Linux like a Tesla on 'Insane'.
I'm sure that Win10 will cause another great 'shedding' of laptops. So great for the economy, MS is almost better than The Fruit.
But I digress, this is summarizing the current state of earthquakes.
Texas now has two new zones opening up. I think this brings the total up to 10 (maybe). As we know, they have these huge saltwater injection wells, just like OK. They mainline the Precambrian at tremendous volumes but have never caused any problems. It's only when they bring in frack waste that they start earthquakes. When people complain, the Texas Conspiracy does a great job in eventually moving the waste to another hole, where the earthquakes start again. These people are stoooopid, and dangerous. Texas deserves them.
They've shoved the frack waste up north, and there might be a lot less of it. Let Kansas get the shaking! I'll change this opinion when we get some good thrusts again near the city.
Okay, here we go again. Fracking waste, mainly for gas in shale, contains fresh surface water, and corrosive agents. This stuff is brutal to the 'glue' holding the highly-stressed granites together. The adhesion points, consisting of the strong silicates dissolve and break. Each time you see a small earthquake, another zone has broken free. Depending on the fractal states, these small earthquakes most likely build up to a bigger one. Only the maximum earthquake can be said to cause a stress shadow (no more earthquakes for a while). The little quakes have no role in making things safer.
New Madrid was a natural seep caused by shifts in the Miss. River, probably after the last glaciation. It probably took thousands of years to build up to the maximum. Now it is a dead fossil, but other zones can activate. They require water, and dams do a nice job. I have hopes for Virginia!
