Yellowstone National Park is located in the United States and has been an attraction to a gargantuan amount of people over the years. This park has beautiful scenery with its motley wildlife, and its geologic features such as hot springs and geysers as it sits over an active geothermal area. People find great joy in visiting Yellowstone National Park, but a handful of people know the potential omnipotent danger that comes with visiting this area. This land is home to a super-volcano that has erupted roughly about 600,000 years ago, causing a great impact. The term super volcano refers to a volcano capable of producing an eruption with an ejecta volume greater than 1,000 km³. This is thousands of times larger than normal volcanic eruptions, making it known as a super volcano. The super-volcano in Yellowstone has massive power that's definitely life threatening and can create a significant amount of damage in a matter of minutes.
A super-volcano isn't just any ordinary volcano. If a super volcano ever erupts, it may result in the mass destruction of man-kind on Earth. A super volcano has the capability of producing an eruption with an ejecta volume greater than 1,000 km³ Volcanic eruptions are categorized by the Volcanic Explosivity Index (V.E.I.) and the scale goes from 0-8 with 0 being non-explosive and 8 being a super volcanic eruption. Yellowstone isn't the only active super-volcano. Other super-volcanos include the Long Valley Caldera (located in east-central California), Valles Caldera(located in Northern New Mexico), Lake Toba (located in North Sumatra, Indonesia), Taupo Caldera(located in New Zealand), and Aira Caldera (located in southern Japan). According to National Geographic, "A caldera is created after a volcano erupts. The eruption blasts away the top of the volcano or causes it to collapse inward. The circular "dent" that results on top of the volcano is a caldera, which can be several kilometers wide.
