correct me if I’m wrong but a controlled effort with managed pressurization could work
one would have to inject massive amounts of water deep into the crust to cause a true quake into an area already rather unstable
a steady diffuse stream of water on or near the surface would steam and not infiltrate at all...or at least it seems
but how to collect steam without capping part of it...or maybe a number of contained caps like well pointing in wet areas for pipe laying to dry out the dirt?
what sort of metal can withstand volcano temp numbers to withstand it for sustained use?
Note to myself
should have read it
they want to inject into a sleeping caldera
I was under the impression they wanted to use a steady hot one
