nobody really knows but if you want to read more about it this is a very good site to look into
Based on the latest evidence, eruptions the size of the giant Yellowstone and Toba events occur at least every 100,000 years, Sparks said, "and it could be as high as every 50,000 years. There are smaller but nevertheless huge eruptions which would have continental to global consequences every 5,000 years or so."
Unlike other threats to mankind -- asteroids, nuclear attacks and global warming to name a few -- there's little to be done about a super volcano.
"While it may in future be possible to deflect asteroids or somehow avoid their impact, even science fiction cannot produce a credible mechanism for averting a super eruption," the new report states. "No strategies can be envisaged for reducing the power of major volcanic eruptions."
The Geological Society of London has issued similar warnings going back to 2000. The scientists this week called for more funding to investigate further the history of super eruptions and their likely effects on the planet and on modern society.
"Sooner or later a super eruption will happen on Earth and this issue also demands serious attention," the report concludes.
There are, however, several volcanoes around the world that can cause catastrophy with a violent eruption.

nobody realy knows. because the only evidence of that happening is from fossils. nobody ever took an acount of it happening because it was to long ago. and also volcanos are very hard to predict as it is. i would say we are long over due for a supervolcano though. wouldn't you?
