What surprised scientists is that Helium-4 appears to be the strongest predictor of activity, as demonstrated with other volcanoes. The latest reports show that the emission rates of crustal helium- 4 from Yellowstone exceed (by orders of magnitude) any conceivable generation within the crust.
Helium-4 (4 2He or 4He) is a non-radioactive isotope of the element helium. It is by far the most abundant of the two naturally occurring isotopes of helium, making up about 99.99986% of the helium on Earth. Its nucleus is identical to an alpha particle, and consists of two protons and two neutrons.
Alpha decay of heavy elements in the Earth's crust is the source of most naturally occurring helium-4 on Earth.

Except that they are not prisons.. and people actually live there. They are not empty.. they were just some very bad real estate decisions. When they put some 2,500 + units up for sale.. they sold a whopping 220 units. People in that part of the world simply can't afford what they are charging for them. They are certainly not cities built to hold Americans after a super volcano blows up.

Math... Pressure, crust thickness, swelling rate, earthquake frequency and intensity, and of course old faithful being regular.

You are right, there is no completely accurate way to predict an eruption.
The 5k value i used above was based on the upheaval rate.
There are determining factors that will show that an eruption is pending. Those factors aren't present at this time and the best theory going.
Sure there could be an eruption tomorrow, but not on the level of a supervolcano.
the geology of yellowstone is the best indicator of what's happening under the surface.
drastic changes in the thermal features of the park are your best bet of an impending eruption.

ALL of revelation happens, on the micro-scale, every time God pulls the veil back from someone's eyes and shows them the transpersonal.
People keep expecting it to happen on the macro-scale. But that's not the way it works.

Just creepy, and here I am paranoid about the San Andreas fault slipping. Between this economy collapse, world war possibility, and this, America might be heeded the same way as the titanic.
