"It's a bad place, there's nothing to do here." Hah, incidentally I did manage to get a few screenshots from a big supercollapse magma piston in stonesense some time ago:

It is called the onacloV because it's a backwards Volcano.

I kinda underestimated what a tidal wave of magma would do and it overtopped some of the edges of the fort, those areas are safe when I've only got the magma pumps running, and if I only drop the two slit northern, massive block southern, and dump the cistern over the animal pastures they remain safe.
The onacloV sits up against the edge of the map and everything pours straight towards the fort to hilarious effects.
