Researchers solve mystery of Super Volcanoes

Super volcanoes on Earth in Focus - Scientists have deciphered the mechanism of super volcanoes. Accordingly, the density differences in the respective magma chamber for the eruptions are particularly responsible.

Density differences in magma chamber responsible for explosion

The findings supported a-days now provides a better understanding of the super volcanoes and also helps to better identify risks for a normal eruptions and volcanoes. Because liquid magma has a generally lower density than the surrounding rock , it has flourished and can thus penetrate the surrounding crustal rocks . After defining at least 1000 cubic kilometers of molten rock ejected during the explosion of a super volcano. The Super Volcanoes left after the eruptions no volcanic cone , but a crater . The size can be up to 100 kilometers.

The dinosaurs died out by an exploding super volcano?

The last so-called super volcano exploded 10,000 years ago. Super volcanoes are especially able to change the climate sustainable. They are led , among others, as one of the causes for the extinction of the dinosaurs. This , however, only indirectly , because a supervolcano exploded supposed to have covered by the ejected ash clouds the sun for years , what should have led to a dramatic climate change and the extinction of numerous species . As examples of radicals of super volcano in the Lake Toba in Indonesia as well as the Lake Taupo is to perform in New Zealand. Scientists have presented and published their findings in two articles in the prestigious publication " Nature Geoscience
