Super Volcano’s

Unlike my first post this is something that will happen at some point in time. The volcano most people know about is the one under Yellowstone national park. If you don't then your gunna.

The reason the Yellowstone national park has most of its amazing futures is because of a volcanic hot spot. Under the ground the water pools, the hot spot heats the water and the trapped water needs to escape. In some cases it can just leak out, in others it creates a geyser.

This hot spot is that same type of hot spot that created the Hawaii Island chain. It heats the crust above it until the crust melts enough to cause an eruption through the last solid piece. For a thin ocean crust that means relatively soft explosions. However when the crust is thicker, like a continental crust, it causes explosions more powerful then those of the atom bombs dropped in Japan. On top of this the expositions happen every 700,000 (about) and its 5,000 (about) years over due.

So, big trouble right? Not really. We are talking geological time; let’s say I tell you some thing happens about every 100 years, you wouldn't be surprised if it happens in 150 years. So expand that comparison to the number above...700,000 goes up to 750,000 this reasonable. That gives a 45,000year difference.

However this works backwards to 650,000 is also reasonable. So there is a 100,000 year time frame that the volcano my blow. So the question is will it blow in your life time, chances are no. will it blow yes. It’s kinda like Russian roulette.
