BILLINGS, Mont.-- Parts of the collapsed, restless volcano in Yellowstone National Park are swelling faster than has ever been recorded.

Geologists from the University of Utah say two domes inside the Yellowstone caldera have steadily inflated at two to three times the rate as some of the most rapid movements recorded between 1923 and 1984.

"We've gone to this really pronounced, and I would say unprecedented, uplift of the caldera," said Bob Smith, a Utah geologist and one of the leading researchers into Yellowstone's busy volcanic life.

Smith presented some of the new findings Wednesday to the American Geophysical Union meeting in San Francisco.

Hi, Just replying out of the SW Pacific field view , I have noticed there is a lot of ongoing earthquake activity in the Antarctica, Sth America, Nazca Plate  and Central America Regions these last 6 months, but nothing really happening on any major scale along the West American Coast, or the Fiji/Tonga region for that matter?.
IMO there is certainly got to be some kind of buildup of pressure along that section of the American Continent, and what you showed there on that map of Yellowstone doesn't look too good, perhaps the same at Mt St. Helens?.

The Pacific Plate Northward movement cannot keep shifting straight up from the Antarctica, Sth America, Nazca Plate  and Central America Regions towards the Kuril Islands and the Aleutian Islands BYPASSING the West US and or the Fiji Islands/Tonga Region without some kind of stress building up.

Something is gonna SLIP  or BLOW UP big time soon, either on the east side of the Pacific Plate (Fiji, Tonga, Solomans, Papua New Guinea)  or West side ( California. Oregon, Washington, BC) IMO.
