Alternately, you could allow the magma to degass as it rises, cool it a
bit, then pump it back down another hole. (Similar to the CO2 degassing
of Monoun and Nyos.) Given the volume of magama involved, you'd need
some mighty fat pipes or a bunch of wells.
Of course, you'd wind up dumping a lot of sulfur and other nasty stuff
into the air. While objectively a much better option than enduring an
eventual magacaldera eruption, I'm sure the local population would raise
hell. "I've lived here 70 years, and it ain't erupted once!"
