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.
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.
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.
The Yellowstone volcano is usually called a supervolcano.

From the collapse of a massive magma chamber after it last erupted.
One of only a dozen "super volcanos" in the world. When super volcanos explode it changes life on earth. The last time one went off was Mt. Toba 70,000 years ago.In more technical terms, the Yellowstone volcano is a caldera. Most Caldera volcanoes start out as stratovolcanoes, but this one appears to be an exception.
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.
