What is the most destructive Yellowstone eruption?

What type of volcano produced the caldera that covers most of Yellowstone Park?
The caldera that covers most of Yellowstone Park was produced by a supervolcano. A supervolcano is an explosive volcano capable of producing an eruption with an ejecta volume greater than 1,000 cubic kilometers. The Yellowstone Caldera is one of the largest and most active supervolcanoes in the world.
