They have at least one earthquake a week because the station pumps water down into the ground to create steam to power their turbines. Take a look at this earthquake map. It's a map of all earthquakes in the California/Nevada area for the past week. Check out the area around Cloverdale. There will ALWAYS be at least one quake per week in that area.

    Just don't think it would make a good James Bond movie. "Ah yes Mister Bond I see you managed to find my secret water pump!".

    On a more serious note, it is known that taking gas or oil from the earth causes the ground above to sink. In the netherlands this is happening up north although the effects are of course very small according to those in power (and living above sea level).

    It also causes some small earth quakes. Nothing major. Last one had all the news channels trying to make a story out of some rooftiles that slid off. We don't get good disasters here anymore.

    If this causes a lot of earthquakes because it lubricates the faults might it not be used to untension high risk areas? Put some lubricant in the ground wich causes a lot of small earth quakes to take energy away from the ground so there is not enough left for a big one?

    I have no idea how lethal a 3.9 is but it must be a hell of a lot better for places like LA then a 8.

      As someone who lives with earthquakes (Southern California), I think I can speak with a little bit of knowledge. A 3.9 is a, "huh, why is that light swaying?" earthquake. A few dishes that are sitting in a very precarious spot might fall and break, but no one is going to really notice. For those of us used to living with them, I wouldn't expect much reaction until at least a 5; a 6 which is close, or a 6.5 might actually get me to head for a doorway, assuming it lasts for more than a couple seconds.
      Why is it that people seem to get so worked up over earthquakes? The ground rumbles for a bit, and the bigger ones make for a good ride. The chances of being in a big one, close enough to the epicenter to matter, and being in a structure which collapses, are really small. Yes, there is some danger, but it's probably less then the dangers or breathing the air in LA.

Put some lubricant in the ground wich causes a lot of small earth quakes to take energy away from the ground so there is not enough left for a big one? Well, yes. IIRC, there was a proposal to run down the San Andreas Fault pumping water into holes while simultaneously pumper water out of holes on either side; the theory being that this would let the fault slip a little bit at a time, and therefore prevent a large earthquake from occuring. (Can anybody cite a reference to this?) Not sure why this was never actually done, although the costs of drilling and pumping would be high, the costs of an earthquake would be higher. Probably it was decided that we simply don't understand the mechanism well enough to predict exactly what will happen.

Pumping massive amount of salt water into the faults, then blowing up part of the fault. So the plant in TFA wasn't blowing up faults, but their salt water did grease the faultlines- just like the movie in 1985 suggested.

    The theory is that the water essentially lubricates the fault, making it easier for it to move. The pumping does nothing to create pressure. Instead, it reduces the amount of pressure that has to build up before an earthquake hits. This means we get a bunch of small quakes relatively frequently instead of a big bad one when we least expect it.

    So perhaps they should start similar pumping actions in California to allow for more smaller quakes to reduce the pressure buildup?

      I was thinking the same thing when I read that. Seems like over all a Good Thing[tm]. However, from the FA:
      That event, combined with two significant tremors in 1999, led government officials to reduce the amount of brine injected by a third.
      Perhaps reducing the the amount pumped in increased the likelyhood of bigger quakes. It seems like lubricating the fault line would be the thing to do.

    What is the purpose of this desalinization plant? The article says "The process is intended to decrease the salt content of the Colorado River downstream..." but why would we want to do that? If the purpose was to remove it for human consumption, I would understand. But that doesn't seem to be the case if it is just removing the salt for the downstream river.

    This whole thing reminds me of the Rhine River which was straightened so it flowed faster, causing massive erosion and removing the natural process of detoxifing the water. Eventually, the river had to be un-straightened to fix the problem.

      Try to irrigate your field with brackish water and after few years nothing will grow there.

      Ridiculous portion of Colorado water gets diverted upstream from Utah. Plus, some Utah tributaries have natutaly high salt content. So what flows down after Utah is more salty than it is acceptable for agriculture. Since they have no spare water to dilute it, they have to desalinate.

    It seems that the final cost of your national nuclear weapons defence program also offers you the choice of drinking radioactive water or paying your tax dollars to keep the Colorado river clean.

    To summarise

    "U.S. DOE announces plan to relocate Atlas Moab uranium mill tailings
    During a ceremony, held on January 14, 2000, high on a cliffside bench above the tailings, Energy Secretary Bill Richardson announced a sweeping plan for relocating the Atlas Moab tailings away from the bank of the Colorado River. With this plan, Richardson is addressing the fears of Los Angeles water officials that the water supply for millions of Southern Californians would be threatened if the 10.5 million short tons of radioactive dirt were left on the flood plain of the Colorado River.
    Two big hurdles remain in the drive to clear away the pile, left near Moab by Atlas when it went bankrupt: funding the multi-year project, which the DOE estimates would cost $300 million, and transferring authority from the U.S. Nuclear Regulatory Commission to the DOE. (Deseret News / Salt Lake Tribune Jan 15, 2000)"

    "A bill ordering the Atlas uranium mill tailings dug up and moved from the flood plain of the Colorado River near Moab was approved Oct. 12, 2000 by the U.S. Senate. The measure, which passed the House on Oct. 11, now goes to the president for his signature. (Salt Lake Tribune, Oct. 13, 2000)
    President Clinton signed the bill on Oct. 30, 2000."

    "President Bush has included no money in his 2002 budget to clean up the abandoned uranium mill tailings site near Moab, Utah, where federal officials have estimated 16,000 gallons of water containing radioactive uranium tailings are leaking into the Colorado River each day. Despite legislation passed by Congress last year giving the Department of Energy authority to begin cleaning up the site, the department has set aside no specific funding to get started. (Las Vegas Review-Journal, April 24, 2001)"

    So your deffinition of private property rights includes opting out of being an American - presumably developing nuclear weapons in your garage capable of persuading the Soviet Union to surrender in the cold war. What you are suggesting is that you want to opt out of your own society.
