Yellowstone supervolcano has been the source of intense research by scientists for many decades. It has blown its top three times in history in what have been described as “supereruptions”: eruptions that are approximately 1,000 times more powerful than the Mount St Helens eruption of 1980 which is often considered the most disastrous volcanic eruption in US recorded history. While there are no signs Yellowstone will erupt any time soon, scientists regularly analyse the potential effects of a blast given the scale of previous eruptions.
