Predicting potential supereruptions, including Yellowstone, is almost impossible, according to researchers at Cardiff University.
The team looked at evidence from 13 previous supereruptions, including the most recent one at New Zealand’s Taupō more than 24,000 years ago.
They found that eruptions lasted for varying times, ranging from short periods of days or weeks to decades.
Dr George Cooper, co-author of the study, said in a statement: “Supereruptions can start literally with a bang and collapse of the chamber roof or begin gradually, with hesitancy before escalating into catastrophic activity.
