What is the most destruction that the Yellowstone Caldera has done?

The Yellowstone Caldera has experienced three major eruptions in the past 2.1 million years, with the most significant being the eruption approximately 640,000 years ago. This event released about 1,000 cubic kilometers of volcanic material, creating a caldera that is roughly 30 by 45 miles wide. The eruption had catastrophic effects on the environment, blanketing large areas of North America in volcanic ash, and significantly altering the climate and ecosystems for years. It also led to widespread destruction of flora and fauna in the region, demonstrating the caldera's potential for large-scale devastation.
