2 What is a super volcano? A Super Volcano or a super volcanic eruption is an eruption that ejects greater than 240 cubic miles.

3 When and where? The last one was in Sumatra, called Toba. It erupted about 75,000 years ago. 10 thousand times bigger than MT. st Helens.

4 What did the eruption cause? Deforested most of central India. 800 cubic kilometers of ash into the atmosphere, leaving a crater which is now the largest volcano lake.

5 Yellowstone Volcano? What evidence is there that it is active? Not your typical volcano because of size, scale, and frequency of eruption. The magma is as close as 5 miles underground in some spots, which fuels thousands of spewing geysers, hissing steam vents, gurgling mud spots, and steaming hot springs.

6 Volcano in Mexico Called Paricutin Began as a fissure in a cornfield. Erupted for over 9 years. Got as big as 1,309.08 ft.

7 The biggest volcano on earth. Mauna Loa. One of the 5 volcanoes that make up the Big Island of Hawaii. Scientists think it has been erupting for over 700,000 years. It erupted last in 1984 and destroyed homes and villages.
