Prediction Techniques for Super-eruption of volcano
Geologists from the UNIGE and Peking University have developed a technique that makes it possible to estimate the maximum size of a future super-eruption of Toba volcano in Sumatra. Geologists are interested in the Toba volcano because there is no historical record of human response to a super-eruption of the size that it produced in the past. Such an event would affect the global climate and pose numerous problems, particularly in terms of food supply, not to mention the migration of populations. The Toba volcano in Sumatra caused two of the largest eruptions known on the Earth: the first 840,000 years ago, the second 75,000 years ago, each measuring about 2’800 km, enough to blanket the whole of Switzerland with 7 cm thick of ash, and representing 70,000 times the amount of magma erupted to this moment by the ongoing La Palma eruption.
