The 2010 eruption of Eyjafjallajökull were volcanic events at Eyjafjallajökull in Iceland which, although relatively small for volcanic eruptions, caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010. Now imagine a Supervolcano, which are capable of producing a volcanic eruption with an ejecta volume greater than 1,000 km3 (240 cu mi). This is thousands of times larger than normal volcanic eruptions. The affect large volcano eruption can have on the world can be understood from, The Year Without a Summer, 1816. It occured because of a volcanic winter event, which was caused by a succession of major volcanic eruptions capped by the 1815 eruption of Mount Tambora, in the Dutch East Indies (Indonesia), the largest known eruption in over 1,300 years. The eruption of Mount Tambora was one of the most powerful in recorded history and classified as a VEI-7 event.
When a supervolcano erupts, it will cause untold “disruption”. Those within the vicinity will be incinerated as temperatures from the lava flow can reach up to 500 degrees, meaning all surrounding cities will be utterly destroyed. If you somehow managed to survive the fast flowing lava, the thick ash cloud that would rain down would choke you to death. It will affect the entire Earth, no one would escape. We would all be affected, wherever we were. Global temperatures would plummet by at least 21 degrees. This could last for many years, meaning that all plant life will slowly die off. We will have no vegetables; animals — our meat — will have no food, so humankind would likely starve.
Here the 10 Super volcanoes, that if they were to erupt. They could likely wipe out must of the humanity.
10. Mauna Loa (Hawaii)
Mauna Loa is one of the largest shield volcanoes on the planet with an estimated volume of about 18,000 cubic miles. While there have been several small eruptions over the years, geologists claim that a full-blown explosion could occur at any time considering that the volcano is still active and the last outbreak is assumed to have happened approximately 700,000 years ago. On a side note, the consequences of an eruption cannot currently be estimated properly since the nature of the volcano suggests the fluid lava can spread fast and get cooled just as quickly in the waters of the Pacific Ocean.
9. Tall (Philippines)
Located rather close to the capital of the Phillipines and part of the Pacific ring of fire, the Taal Volcano is known for devastating and powerful eruptions. What is fascinating about this volcano is the fact that it is presumed that the lake surrounding it actually constitutes the remnant of the crater of an older large super volcano. Essentially, if this hypothesis were true then it means that an eruption would release a sufficient amount of gases and hot dust to cover the Earth’s atmosphere for several months. Unfortunately, Taal started presenting several signs of unrest since the 1990s and in 2010 the authorities have risen its alert level, two facts that lead us to believe it can erupt at any moment.
8. Ulawun (Papua New Guinea)
Ulawun is a very large volcano situated in the Bismark arc and among the few mountains visible on a satellite image. This volcano has been active since the 1700s and its last explosion was recorded in 1980 when the Ulawun ejected an incredible amount of ash in the air, while destroying approximately 20 square kilometer of land around it. However, what worried geologists the most consists of the altitude of this volcano, which is slightly higher than the rest in the arc, an element that indicates that it may be at the peak of its structural stability. Not to mention that seism activity is frequently registered in the area.
7. Mount Nyiragongo (Democratic Republic of Kongo)
The Mount Nyiragogo is not only the largest active volcano on the African continent, but it is also the only one with visible lakes of lave inside the crater. People living in the vicinity of the volcano have lots of reasons to be worried: the Nyuragongo has been active for over two centuries and during its last eruption in 2002, the lava covered almost half of a city nearby. Moreover, according to its eruption patterns, geologists estimate that it is about to explode in the near future.
