If you consider the time scale that geological shifts follow, these quakes may have been brought on by the construction of the dam itself, and the resulting pressure of the entrapped water, which allowed it to migrate into faults that it could not previously penetrate. Great-grandmother Nature.

      Yes, quite likely.  In both cases, changing the properties between two 
adjacent geological layers promotes a degree of instability.

      I often joke with Norm, the soil specialist at Tonto National Forest, 
saying that he is a Soil Psychologist since he deals a lot with disturbed 
soils.  :{b

In this case, Mother Nature could BE the fracker. :-(

       No, but I have a mildly educated idea as to why this is happening, based 
partially on the earthquakes in Oklahoma, which are suspected to be caused by 
fracking.  The geology in the vicinity of Lake Mead has fault lines everywhere, 
the result of millions of years of geological uplifting and collapsing.  The 
area is a tremendous matrix of uplifted ridges and narrow canyons.

       Lake Mead has been filled for almost a century now, and it sits in the 
middle of all this with fault lines in every direction beneath it and to every 
side.  It is very likely that water from the lake has been passing into these 
faults, especially at the deeper levels where the water pressure will be quite 
high.  This water may have entered into areas within the faults where it 
provides some level of lubrication to the surfaces.

       It's not nice to screw with Mother Nature.

Have you been invaded by a swarm of frackers?

        Looking at the current NAM charts shows that there is a significant

        Out here in the mild, mild west we're having our first rain in
over 60 days here in Phoenix, and the rain will continue on and off for
about a couple of weeks.  We're also having a swarm of earthquakes
north of Kingman, fairly close to Lake Mead and Hoover Dam.
