The researchers identified the younger of the pair, dubbed Grey’s Landing super-eruption, was Yellowstone’s largest and most violent event.
Dr Thomas Knott, a volcanologist of University of Leicester and the study’s lead author, said: “Based on the most recent collations of super-eruption sizes, it is one of the top five eruptions of all time.”
The study suggests the hotspot, which today is responsible for Yellowstone’s world-famous geysers, mudpots, and fumaroles, is likely waning.
However, Dr Knott added the research is not a call for complacency.
