A federal facility that pumps salty water 14,000 feet into the Earth's crust probably is associated with a magnitude 3.9 earthquake that struck the Utah-Colorado border this month, an official said.
The U.S. Bureau of Reclamation facility removes salt from the Dolores River, then pumps 230 gallons of brine per minute into deep wells in Utah's Paradox Valley Area.
The facility has caused thousands of earthquakes in the area since 1991, but most have been too small for people to feel. The 3.9 quake, which struck Nov. 6, was felt in Grand Junction, some 60 miles away. No damage was reported.
``We have a seismic network set up for measuring and recording any events associated with the injection process, and it appears this earthquake was one probably associated with that process,'' said Andy Nichols, manager of the federal facility. ``Every once in a while there's a large event felt at the surface, and this was one of those events.''
and the disclaimer: no, i'm not claiming we or anybody purposly caused the 9.0 earhtquake, just stating that yes, indeed, we DO cause at least SOME earthquakes. the wake of the disaster that happened this week is a natural time to discuss such issues.
the rest of your lists, i'd pretty much agree with you, if that makes you feel any better.
