She told viewers: “Yellowstone is a hotspot volcano and you can see, from the map, the state of Idaho and the current volcanic field. 

“What we can see is numbers next to these volcanic centres which represent millions of years since they erupted. 

“Now if you take into account the last six million years, then the average reoccurrence interval is about 996,000 years. 

“If you only looked at the Yellowstone volcanic field, then many calculate that it erupts every 600,000 years, but it is actually a 740,000-year interval.”
