Dave, Peterborough asked:
Can you just give us a quick update on the situation with Yellowstone? Whatís happening there?
Yellowstone is a huge system and between eruptions which generally happen every six hundred thousand years or so itís not a dead system. Instead the magma chamber is inflating. Indeed, we can see that now at Yellowstone Ė a very slow rate of deformation - but itís certainly inflating, preparing for its next eruption which probably wonít happen in our lifetime.
