Yellowstone...Time to spread some fear.

Yes, look at this small extract from the link i provides ( post doctoral position).
The Yellowstone volcanic system is one of largest volcanic systems in the world and is a major area of seismicity, including a M7.5 earthquake in 1959, the largest historic event of the western U.S. interior. In 2002 alone, there were more than 2350 earthquakes at Yellowstone, including over 500 triggered by the Nov. 2002, M7.9 Denali earthquake. The Norris Geyser Basin is located at the NW edge of the 640,000-year-old Yellowstone caldera and is in the vicinity of several post-caldera rhyolite flows and at the intersection of large active faults. Seismicity at the Norris area is characterized generally by swarms, but includes a M 6.1 event in 1975. The caldera has a dynamic deformation history, uplifting and subsiding up to 10 meters over decadal to millennial timescales. Historically it rose 1 m between 1923 and 1985, then subsided ~25 cm to 1995, and in the past ~7 years the NW caldera, including Norris, appears to uplifting. Importantly, the recent uplift has been accompanied by expanding areas of hydrothermal activity in Norris Geyser Basin, including the creation of hot springs and fumaroles north of Norris and renewed activity of the Steamboat geyser, the world's tallest. In July 2003, increased hydrothermal activity required closure to visitors of parts of the Norris Back Basin. The relationship between these diverse phenomena, however, remains unknown. The uplift itself may be due to magma intrusion, release and expansion of hydrothermal fluids through a permeability barrier, or some other mechanism.

There's also one like this building up under Mozambique-Ethiopa area. Hard to get a good reading on something like that when it's in the middle of no wheres.
Another thing that we're over due for is an asteriod or comet hitting Earth. They typically come around every 100,000 years, but depending on what they mean by that we coulda already had our fill of that what with Tunguska and this other one that nailed a part of the Saudia Arbia desert

DAMMNIT!!!!!!!!
hey as long as it erupts after CIV IV comes out im happy

also has anyone ever heard of that fault that lies near the Mississippi River, i know it created Reelfoot Lake, but it is due to create an earthquake of at least 9.0 that would shake most of tennessee. that would ruin my day

I, being from the very volcanic pacific northwest (too young ot remember mt st hellans go though), knows this:
The magma chambers ARE filling in Yellowstone, the area is rising.
The older the volcano, the longer it takes to finally erupt, we should have plenty of warning.
The next volcanos in the cont US expected to erupt is Mt. Baker and Mt. Hood, in Washington state and Oregon respectivly.

Well, so we DID finally find the Saddam's WMD ?
