In a study released last year, the United States Geological Survey said possible hazards could include hydrothermal explosions, when steam breaks through the surface and forms a crater. That has happened 26 times in the park's 127 years of record-keeping. The USGS discounted chances for cataclysmic eruption of the caldera, noting that the hot, active magma chamber below Yellowstone has turned into "largely crystallized mush." But the same study also said: "Depending on the nature and magnitude of a particular hazardous event and the particular time and season when it might occur, 70,000 to more than 100,000 persons could be affected; the most violent events could affect a broader region or even continent-wide areas."

Here's a bit about Chris Sanders:
www.xing.com...
Apparently, there are a least 2 Chris Sanders who are Geologists.
The email I sent was returned undelivered so I found different one.
Also left him a phone message to join us.
This is the one that did the youtube. I don't see any geology training in his education listings.

hello im usuelly a lurker but im joining up just to post this
im in wyoming , near yellowstone national park.
recently, starting earlier today at around noon, i started smelling this weird smell in the air, smells like sulfur but a little bit more "bitter" smelling
i cant figure out what it is, but it hasnt gone away. i drove a few miles away from my house to the town, and the smell is still there in the air. everyone else can smell it too. i called the news channel and they said they are going to run a report on it on the morning news tomorrow
i dont know if its related to yellowstone or not or if im just paranoid. but thought i would share this. take it with a grain of salt.

For people determined to calculate earthquake Richter magnitude from GEE seismograph charts, I've found another enlightening page.
Please note that on GEE EQ amplitude is in microns. 1 micron = 1/1000 millimeter.
Now I need only to find more info on that distance correction factor.

this is the first time i've heard anything as positive on this, and from the "horses mouth", relatively speaking
