I’m sure drilling a hole will help!!! What could go wrong??
Well, as long as you don’t hit the magma chamber, you could drill close by, and yes, you could in theory give the heat a place to go, but as I stated, its not the heat per se that is the reason calderas explode and leave craters 25 miles wide... its the pressurized gasses in the magma that suddenly have an scape route once a fracture to the surface occurs... simply taking heat away from the magma does nothing to lessen the insane pressures that are build up in these calderas from the pressurized gasses.
That’s the force behind the explosive nature of the caldera volcano in my understanding.. not simply the hot magma.. if it was just magma building up pressure, you could simply offer an escape route and control the magma flow... but the minute you piece the magma chamber, all of that pressurized gas will suddenly have an escape route... and KABLOOEY.... 25 mile crater and a Nuclear Winter lasting a few years.
