1. Natural Disaster Project: Yellowstone Super Volcano
Andrew H.

2. General Facts
The entire Yellowstone national park takes up 2,219,791 acres of land
Home of lakes, rivers, mountain ranges, canyons, along with the famous Old Faithful Geyser
Is the source of ½ of the geothermal features of the world
The area has lots of volcanic rock and lava flows
It’s home to the largest super volcano in North America

3. About the Volcano Itself
Some believe that the Yellowstone area is right above a “hotspot” within the mantle
Magma gets caught in a chamber near the surface, magma pushes up, creating a bulge on the surface, the surface cracks, eventually falls into the chamber, forming a large hole in the ground that eventually gets filled with the magma

4. Magma chamber bulges the surface
Magma chambers causes the surface to crack apart (and volcanic material is released)
Surface collapses into the chamber
Magma fills in the hole left behind

5. Eruptions Believed that there’ve been three cataclysmic eruptions 1st
One of the five largest known eruptions of all volcanoes
Formed a caldera 60 miles across
Formed the Huckleberry Ridge Tuff

6. Eruptions Cont. A younger, similar, not as large eruption
Caused the Henrys Fork Caldera and the Mesa Falls Tuff
Most recent eruption
Formed the Yellowstone Caldera, which is 35 miles wide, 50 miles long
Caused the Lava Creek Tuff
Volcanic ash (believed to be from this eruption) can currently be found in areas like California, Louisiana, and Iowa
