When is Yellowstone meant to errupt?

Yellowstone is not meant to errupt, it is expected to errupt. The Yellowstone supervolcano is located in the western United States and is one of the largest volcanoes in the world. It is estimated that the volcano has erupted three times in the past 2.1 million years, with the most recent eruption occurring about 640,000 years ago. Scientists believe that the volcano is due for another eruption, but it is not possible to predict when this will happen.
