How far down need one dig before there is a volcanic eruption?

It simply cannot be done - it would take a "world buster" bomb as described in science fiction magazines. They don't exists nor does the technology for it.

When digging a hole, the heat flow from below would melt any know material well before the tool was able to reach the material that would erupt OR before enough instability of the crust were such that a breach would occur. The crust is like a self-healing tire; the hole will close before any damage is done.

You mean like the soil and rock beside the hole would just collapse into the hole?

The pressures and temperatures at that depth would squeeze the hole shut.  Rocks at those pressures and temperatures behave vastly differently than surface rocks- they flow instead of acting like solid bodies.  Think trying to keep a hole open in a ocean of marshmallows.

Ah, so that explains why I can never find the hole in the water where my fingers poked through. [:)] Thanks to you Bass.

I guess the original question related to volcano in the sense of a mountain gushing molten rock - and if so, then the responses from my elders and betters is entirely correct.

However, volcanic/ geothermal activity is not wholly confined to molten rock, remember the indonesian mud volcano?

suggests it could have been man made?

My mums cousin Don Maclean (compare / commedian with big teeth) gave details about making a man made volcano. He would lay on his back, fill his belly button up with talc, and slap both sides together causing the talc to errupt. Hope this is helpful
Science is continually evolving. Nothing is set in stone. Question everything and everyone. Always consider vested interests as a reason for miss-direction. But most of all explore and find answers that you are comfortable with
