The Yellowstone volcano has erupted three times in history – 2.1 million years ago, 1.2 million years ago and 640,000 years ago. Scientists have previously revealed that, should an earthquake occur, it could take less than two weeks before a catastrophic reaction event with the potential to wipe out a huge part of the US is triggered. However, even if locals manage to escape the initial blast, they could still be in danger for up to a month afterwards, it has been revealed.
Robert Smith, from the University of Utah, is in charge of the seismometers around Yellowstone National Park.
This technology is designed to detect any change in activity, and give anyone in the immediate area some valuable time to evacuate.
However, Mr Smith warned during the History Channel’s 2014 series “Deadly Volcanoes”, that the pyroclastic flows created following an eruption could continue for to up to a month.
He said: “What Yellowstone would create would be a massive volume of materials.
