Utah Desalinization Plant Causes Earthquake
mknewman writes "A Utah desalinization plant which removes 260 gallons of salty brine from a river which feeds the Colorado river has caused a 3.9 on the Richter Scale earthquake, noticeable by people 60 miles away in Grand Junction.

Well, in the interests of refecting what the article actually said, mknewman might have posted:, "A Utah desalinization plant which pumps 260 gallons per minute of salty brine to a depth of 14,000 feet underground, is probably associated with an earthquake measuring 3.9 on the Richter Scale, and noticeable by people 60 miles away in Grand Junction.

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 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.

Boy, you sure don't ask for much, do you?

. . . but I didn't realize that Mormons also got all shook up over plain old salt.
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?
Wired had an article the other day regarding the environmental impacts of another desalination plant, this one in Arizona.
We better hurry up and give up some rights before the terrorists start pumping water underground and causing earthquakes.
Trying to use sarcasm in text-based forums does not work.
The salt in the Dolores River comes from natural underground salt formations. Ground water passes through a collapsed salt anticline and becomes brine. You can read the technical report at http://water.usgs.gov/pubs/wri/wri02-4275/ and see photos at http://www.geo.mtu.edu/~jeh/Photos/Captions/capday 4.html.
Natural salt water is not uncommon in this region. The Great Salt Lake formed long before the Industrial Age.
