    Reminds me of something I heard about a geothermal generator near Cloverdale, CA. 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 [usgs.gov] 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.

    For someone who grew up with nuclear movies, in wich every problem was solved or involved nukes, this is very very nice.

    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

    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.
      • I fully support this theory of lubricating the fault line by pumping - it seems the added benefit of releasing pressure build-up is nothing to scoff at either. The fact that government officials might notice significant tremors while the pumping is going on disturbs me to no end though - I didn't think the tremors would be that significant!

        Can anyone here verify this theory - oh, wait, nevermind. This IS slashdot, afterall.

    Back in the late 1960s or early 1970s, there was some injection of water into wells in the Denver area (I forget if it was at the Rocky Flats nuclear weapons plant or at the Rocky Mountain Arsenal nerve gas/pesticide site). It resulted in the same types of low level earthquakes. I recall one morning, while I was carrying my full bowl of cereal into the living room to watch the cartoons, a magnitude 4 (or thereabouts) earthquake struck. I had to stop to prevent my cereal bowl from spilling milk onto the floor. The water injection was stopped, but I don't recall if it was to prevent further earthquakes or some other reason.
    • Denver also had a problem with earthquakes from oil drilling with the shale industry in the 70s & 80s (before it went belly up in the mid/late 80s). Water was pumped down into the areas to help make slurry for transport.

    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 [swipnet.se] 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.
    • I seem to remember reading that the salt content of the Colorado is unnaturally high due to removal of desalinated water for irrigation and human consumption. I believe it was already higher than other US rivers because of the geology (saltier rocks?). Perhaps this is just to reduce the content back to natural levels so it doesn't kill vegetation or screw up the fish runs or whatever the ill effects of a lot of salt are.
      • Right... like the fact that the Colorado dries up before it ever reaches the ocean doesn't effect the fish runs any! No, this is purely to benefit the people downstream pumping water back out of the Colorado...

    • 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.

      Your argument would make sense only if the farmers and cities were distilling the water and returning the solids to the river. They're not, so there's no "tragedy of the commons" here.

      The salt in the Dolores River comes from natural underground salt formations. Ground water passes through a collapsed salt anticline and becomes brine.
