Another is the Yellowstone Caldera.
When/If that one blows it will wipe out everything including FEMA.

And deeply misleading. There's no particular evidence whatsoever Yellowstone is nearing a supervolcanic eruption. There's been a great deal of misrepresentation, misunderstanding, and flat out false info regarding this in the media, documentaries, and on a boatload o' crappy websites.
Another problem is an overfocus by the public, documentary makers, etc. on exotic stuff with a very, very, very low probability of happening - like a Yellowstone supervolcanic eruption, or things that have been scientifically debunked, like the supposed megatsunami on the East Coast from Cumbre Vieja volcano collapsing.
This causes people to ignore things with a very realistic chance of happening, like an M 7 to 7.5 earthquake in Salt Lake City, that, while, it wouldn't end life on earth, would make Katrina look like a joke.
Whoa! That's what I call a big volcano.

Don't forget the uplift movement going on at Mammoth Lakes.

Well I'm already in a crappy mood today, I may as well pay them a visit, too. :-o
This century I will be concerned with terrorism, illegal immigration, etc. for the next few years. Be sure to ping me when the volcano is getting within a month or two of erupting.
