This part of Indiana I live in is pretty flat. Dull, right? So I figure, why not have a volcano? Now… I get my magic drill machine that can drill as deep as I want it to drill.
If I drill a deep enough hole, say through the crust of the Earth, will it turn into a volcano?
Still would be quite difficult. We think about 90% of accessing magma never makes it to the surface simply because it loses overpressure. It mostly comes down to how vicious the mama is and what it’s overall volatile content. All is which is dependent on the magma temperature, access to water, and silicate composition.
