An eruption would be capable of returning humanity to a pre-civilisation state The mammoth explosions could release over 1,000 gigatons of ash into the air Super eruptions may occur as regularly as once every 17,000 years The window between super-eruptions could be as short as every 5,200 years The next volcanic 'super eruption' with the power to return humanity to a pre-civilised state could be due much sooner than previously thought. Experts have previously predicted that the massive eruptions are likely to occur roughly once every 45,000 to 714,000 years. This assessment, made in 2004, is now being challenged by new findings which say that the most likely time frame is just 17,000 years. Researchers also estimate the eruptions could happen as often as once every 5,200 years. +3 The next volcanic 'super-eruption' with the power to return humanity to a pre-civilised state could be due much sooner than previously thought.
