Tectonic Setting:
To begin, the tectonic setting of north western Wyoming explains a lot about Yellowstone. The crust underneath Yellowstone is restless. There are some major faults along the Teton, Madison and Gallatin Ranges that pass through Yellowstone; these all existed before the volcano was there. The North American plate is the biggest plate that Yellowstone is interacting with. There is a divergent boundary along where Yellowstone and the North American plate meet. The most apparent faults in Yellowstone are as follows; the Minor Plateau Faults younger section, Post – Lava Creek faults in North Western Yellowstone, Mallard Lake resurgent dome faults, Elephant Back fault zone, and Sour Creek dome faults.
Main Hazard: Equally important, Yellowstone has many main hazards. Yellowstone is a super volcano. The difference between a normal volcano and a super volcano is not very obvious until you look at the inside structure. A normal volcano typically has a single column of magma that comes from within the earth. It breaks through the top of the mountain and spews out the entire column. A super volcano is quite a bit different though. A super volcano begins with a column of magma, but instead of breaking through the surface it stays underground. The magma then starts heating the crust and slowly begins to mix
