A new study has discovered a powerful force that is now driving evolution on Earth.

How does the huge volcanic eruption in the Yellowstone National Park area compare to other large historical volcanic eruptions?

The three major volcanic eruptions in Yellowstone Park emit more material than Mount St Helens (1980), Mount Pinatubo in the Philippines (1991), Krakatau, Indonesia (1883, erroneously called Krakatau), and Tambora, Indonesia. (1815) erupted much more.

All largest eruption in the past 2 million years occurred at Mount Toba on the island of Sumatra about 74,000 years ago. The volume of that eruption is estimated to be 670 cubic miles (2,800 cubic kilometers).
