Quote from: profoundmy idea is not to drill into the caldera but into a the gaseous region above it to release the gas pressure.A volcano is not like a can of baked beans - there is no air pocket at the top.
The gas that drives the explosion is dissolved in the molten rock, under immense pressure.
Just like when you shake a bottle of cola, and open the lid: it is when you release the pressure that all the dissolved gas comes out of solution, and you get an explosive eruption.

That is not true at all.
go get a bottle of cola.shake it violently.
now turn the screw lid very slowly and gently until you hear the the hiss of escaping gas...leave it for a few minutes and all the excess gas will have been released gradually.no explosion whatsoever...see?
