2.1 million years ago, an eruption near present-day Yellowstone ejected about 2500 cubic kilometers of material, and created the Island Park Caldera. This is not much less than the largest measured eruption in history, the 2800 km^3 eruption of Mount Toba, about 74,000 years ago.

In terms of eruptions in the states themselves, the largest eruption goes to the 1980 eruption of Mount St Helens. The largest eruption to occur on U.S. soil was the 1912 eruption of Novarupta in Alaska. This eruption was an order of magnitude larger than the Mount St Helens eruption, but at the time Alaska was not a state.
