Although there is evidence that erupted several times over the 4.5 billion years of http://www.strange-facts.info/strange-and-interesting-facts-about-planet-earth, NASA claims that 2012 will be held such an event. The terms "super volcano" and are relatively new and refers to a volcano whose explosive eruption would release 10 thousand times more lava than the eruption of Mount Saint Helens catastrophe in 1980, one of the largest recent eruptions.

Throughout its history, Earth has undergone several , proof being the ash layers covering large areas of continents and huge craters up to 100 kilometers remaining after eruptions in Indonesia, New Zealand, the United States and Chile . Most supererupţie in history seems to have occurred in Sumatra. 74,000 years ago, Mount Toba erupted and lava covered an area of ​​more than 28,000 square kilometers. By comparison, the magma which surfaced in 1883 in Mount Krakatau was laid over only 12 square kilometers.

 While conducting research for vulcanology still find out what causes supererupţie, they say their data indicate that such an event will not happen too soon. Trying to determine the http://www.strange-facts.info with which they place these supererupţii, scientists have concluded that once in a million years occur supererupţii 1.4.

Despite these calculations, scientists say that it is imperative that every million years to occur supererupţie. Many millions of years may pass until a super volcano to erupt. Vulcanology can not accurately predict a super volcano moments will erupt, but monitoring of active volcanoes to show that humanity will not be witnessing a supererupţii 2012.
