[Rockhounds] There may be a supervolcano under Mt. St. Helens

[Axel Emmermann]

Ok, I'll stay... but you'd better be serious about that safety valve ;-))))

Anyway, to start a supervolcano the magma chamber needs to be more than vast
alone, the magma itself needs to be rich in gases. It needs to expand,
refill the chamber after the initial blast has evacuated  the first magma.

See the experiment with the Cola bottle and the peppermint...
