Well, these are government employees (I checked the first three (of the 5) listed as authors of the article)...

Jacob B. Lowenstern, Ph.D. U.S. Geological Survey
ROBERT L. CHRISTIANSEN, research geologist, U.S. Geological Survey and YVO Scientist-in-Charge (University of Utah)
Robert B. Smith Professor of Geology & Geophysics (University of Utah)


>I doubt the qualification of either the scientists or the reporters. A yearly chance of 0.00014% would mean an even chance in abozt 5000 years. Doesn't really fit with the asteroid comparison and the eruption data mentioned in the article.

>>The odds of a catastrophic eruption at Yellowstone are 1 in 730,000 or 0.00014% (better than the lottery).

>>Although it is possible, scientists are not convinced that there will ever be another catastrophic eruption at Yellowstone. Given Yellowstone's past history, the yearly probability of another caldera—forming eruption could be calculated as 1 in 730,000 or 0.00014%. However, this number is based simply on averaging the two intervals between the three major past eruptions at Yellowstone — this is hardly enough to make a critical judgement. This probability is roughly similar to that of a large (1 kilometer) asteroid hitting the Earth. Moreover, catastrophic geologic events are neither regular nor predictable.

>>>Terry, I thought that the whole Las Palmas issue was revised to be a very unlikely occurence. As to to the mega-caldera in Yellowstone, there would have to be a lot of signs a long time before that happened and there are few, if any, signs that anything is happening there.

>>>If you want to look at potential surprises, the New Madrid fault in the US Mid-West could provide one. Could annihilate Memphis or any number of Mississippi cities.

>>>Gamma ray bursts, asteroids....anything can happen.
