Mike your map of the subduction zones and how the U.S. plate is moving south verses the pacific plate points out why the quakes are moving to the north of the Reno area. That has to be lava, No doubt about it. It is created by the plates moving against each other and thats all scientific fact so I am getting pretty sick and tired of the USGS blowing smoke up our rears.
If all that Lava finds a weak spot it is going to pop like a cork.
The plates are moving allot and thats why we are seeing volcanic type earthquakes all throughout Nevada and Utah. Lets pray that Yellowstone is really its own hot spot and not connected to this in any way.
The 3.0s in the random states that pulled the disappearing acts are not connected to this same event or we would see more in those same areas.
China is rumbling again today with two more after shocks so I'm sure that saga is far from over.

Hi Bill,
I'd love to know where they got their data for that "Discovery" program. That sort of info is news for me! Most sources I've looked at lately give "rise" rates of around three to four inches per year in the past few years. Even at that rate it's considered to be faster than it was previously, but I very much doubt the "three feet" figure -- not even in total since measurements began in (I think) 1923. Of course, anyone who does the arithmetic will say, "Hey, if it's been rising even an inch per year since 1923 then it'd be up around 7 feet higher by now."
True, it would be, if it rose year on year. But there have also been periods when the caldera has fallen...
So anyway, while I have my doubts that Yellowstone's caldera has recently risen three feet, I still am not completely comfortable with the fact that its current rate of rise is significantly greater than it has been before.
