The biggest volcano in the US is Yellowstone.

If it blows, we're screwed.
"The three caldera-forming eruptions, respectively, were about 2,500, 280, and 1,000 times larger than the May 18, 1980 eruption of Mt. St. Helens in Washington State."
"the three largest Yellowstone eruptions emitted much more material than the eruptions of Mount St. Helens (1980), Mount Pinatubo (1991), Krakatau (1883), Mount Mazama (7,600 years ago), and Tambora (1815)."
"Three extremely large explosive eruptions have occurred at Yellowstone in the past 2.1 million years with a recurrence interval of about 600,000 to 800,000 years"
The last one was 640,000 years ago...
Talking about those big pyroclastic "supervolcanoes", I believe one of the biggest is in the middle of the North Island of New Zealand - in Taupo.
When THAT puppy blows, then the World will know.
Auckland (a city of over 1.2 million people in New Zealand), on the other hand, resides on no fewer than 63 DORMANT volcanoes - and is long overdue for an eruption. It is of interest to note that if just ONE erupts, there will be a disaster of cataclysmic proportions...
There is an active volcano off the Bay of Plenty coast of the North Island called White Island - it is continually in a state of eruption, and is known as the "vent" of the country. If the activity ceases, geologists get worried enough to call in the air force to bomb the caldera...!
