It would not take much to set this off. Drilling a hole to it I think would be idiotic. I just watched a show on this the other day. The demonstrated a super volcanoe with pine resin and acetone. As soon as they let air in it mad a vacumn up the tube neck and the whole mess shot out the top of the tube like a rocket. It was amazing. Let me see if I can find a video. No video but I got this
be responsible for the violence of the eruptions. Into a glass flask - the magma chamber - he poured a mixture of pine resin and acetone. the pine resin mimicked the magma, the acetone modelled trapped volcanic gases like carbon dioxide and sulphur dioxide.

STEVE SPARKS: Pine resin is a very sticky, stiff material so it has some properties which are rather like magma and we thought that if we could get a, a gas which dissolved in pine resin, like acetone, then we could get a, a laboratory system which would represent the, the natural case.

NARRATOR: Sparks then created a vacuum above the flask to mimic the depressurisation that occurs in the magma chamber when a supervolcano begins its eruption and the dissolved volcanic gas can expand. When the vacuum reached the liquid it caused a dramatic change. The dissolved acetone suddenly became a gas. This made the resin expand causing violent frothing and blasting the contents out of the chamber.

STEVE SPARKS: These experiments give us tremendous insight into the tremendous power of gases coming out of solution and enabled to drive these very dramatic explosive flows.

NARRATOR: Unlike supervolcanoes, normal volcanoes don't have this vast reservoir of magma and trapped volcanic gases and don't have the potential for such powerful eruptions. But experiments in the laboratory cannot answer the biggest question of all surrounding Yellowstone: when will it next erupt? Scientists face a problem. They have never seen a supervolcano erupt. Until a VEI8 eruption is observed and analysed no-one knows what the telltale precursors would be to a Yellowstone eruption.
