Major Supereruptions in the Earth’s History Were Caused by Deep Water Migration

... cause a voluminous explosion. This mechanism explains the recurrence of supereruptions and their strength. Indeed, making a “time bomb” requires the accumulation of a critical amount of water, which must come from the mantle. Thus, there will be supereruptions at Toba as long as the IFZ continues to subduct beneath Sumatra and brings abnormal amounts of water to the mantle. However, given that the last eruption at Toba Volcano was only 76,000 years ago and the intervals between supereruptions are hundreds ...
