Supervolcano

Yellowstone is one of the biggest supervolcanos in the world and we are living on top of it. What do Scientists say will happen in the event of the next eruption?

I must confess that I am a volcano nerd. I've been fascinated with them dating back to the Mt St. Helens eruption in 1980. My fascination with this part of geology led me to ask the question what would it really take to make the Yellowstone supervolcano erupt? This is what I found.

This may be normal, but I've never seen or heard of it before. Here's video of a steam vent in Yellowstone Lake.
