No. Most of Yellowstone lies outside of the Yellowstone Caldera, though this caldera still takes up a large portion of the park. A larger portion of the park is in the older Island Park Caldera, which partly overlaps the Yellowstone Caldera. This still takes up a minority of the park.
No. Most of Yellowstone is outside of the caldera.
The Yellowstone Caldera, also known as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano estimated to be an area of about 34 X 45 miles (55 X 72 km).
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.
The Yellowstone volcano is usually called a supervolcano.
Most of the Yellowstone Caldera is no hotter than you would expect from weather in that climate zone. The caldera does contain many hot springs, and geysers, some of which are hot enough to boil water.
It is impossible to know exactly how much "destruction" occurred in any eruption that has taken place in the Yellowstone Caldera, but the eruption with the largest volume of lava expulsion took place about 1.2 million years ago.
The Yellowstone volcano is usually called a supervolcano.

The Yellowstone caldera was most likely formed from a series of explosive volcanic eruptions that occurred over millions of years. These eruptions deposited layers of volcanic material that eventually collapsed, creating a large crater or caldera. The underlying hotspot that fuels Yellowstone's volcanic activity has been active for millions of years, contributing to the formation of the caldera.
The Yellowstone Caldera was formed by an Ultra Plinian eruption. Ultra Plinian is the most violent type of volcanic eruption with enormous columns of ash and gas shooting twenty or more miles into the sky and releasing many cubic kilometers of ash.
