I know the film you're talking about Steed, I think rather than a ring of supervolcanoes it was a ring of eruption sites from the main magma chamber which then caused a collapse of the main chamber and a massive eruption, that's IIRC. It was a while back, pretty good film though.
So, if it's not Yellowstone then it'll be the Canary Islands Super-Tsunami, and if it's not that then it'll be an asteroid or some such.
Not a great deal we can do about it, save be ready and try to survive when it happens.
