How the **** was anyone able to measure that chamber pressure, 300 YEARS AGO???
Good question. I have no idea. We’ll have to wait for the resident geologists to chime in. Wonder if they can tell by examining ejecta post-eruption under the microscope? Or maybe there is a mathematical relationship between the pressure and height of the column of smoke and ash? Just guessing...

And in Metric no less!

I would suspect by looking at the magma chamber rock ejected from the last eruption..
Scientists have been studying volcanoes for a long time. The science of magma is fairly well established and they know what Fuji is made out of and where the breaking point, where Fuji finally would erupt, would be.
They probably cannot say to an exactness, but they can say to a fair degree of accuracy what will happen.
First, you get a flux capacitor...
