I was bored and surfing the net tonight and came across reports from GPS devices in and around Yellowstone. You can really get a good look at how uplift changed in mid 2004.

That is approaching 175mm in just over 3 years.
Note: In all the GPS charts the important panel to look at is the bottom of the three. That shows the amount of vertical movement (uplift or subsidence).

Old Faithful GPS. Not quite as pronounced but still 100mm.

Strangely enough Norris has gone down about 50mm.

I find this quote from the USGS site a bit interesting.

As of late October 2007, the total uplift since 2004 at that location is about 17 cm. Chang and his colleagues credit the relatively rapid rise to recharge of magma into the giant magma chamber that underlies the Yellowstone Caldera. They also used numerical modeling to infer that the magma intruded about 10 km (6 miles) beneath the surface. |

yep, a 'giant magma chamber recharging under yellowstone'
does indeed qualify as interesting...
Interesting. noticed bigger uplift but thought it might be normal, even if it is increasing. There is evidence of it rising and falling before anyway.
And in this case interesting must be a synonym for "downright scary and i hope they're wrong"
Don't caldera's "breathe"? This could just be an inhale cycle.

LOL ... yeah, but it's the EXHALE that's the killer! |
