From the most recent, current volcanic eruptions to those of the past, this list names the largest volcanic eruptions in history. With volcanic death tolls reaching tragic proportions, these are not only the biggest and worst volcanic eruptions environmentally, they're also the deadliest. World disasters like volcano eruptions can affect the world on a global scale and test the preparedness and relief our governments can provide. Luckily for the human race, none of these have been supervolcanoes.
Volcanoes are vents in the Earth's surface where molten rock, ash, and gases can erupt or ooze out. Most volcanoes are located along the Pacific Ring of Fire, where tectonic plates can slide beneath one another and cause a disturbance. The size of the volcano eruption depends on how much time a volcano has had to build up pressure -- some of the biggest volcano disasters came after a long period of dormancy.
What are the worst volcanic eruptions ever? Such great disasters, despite the destruction and natural hazards that come along with them, can also bring forth examples of how big our hearts are as we as individuals provide aid alongside our countries. These historic volcanic eruptions caused great disaster, and were certainly some of the biggest ever recorded on earth.
