YELLOWSTONE NATIONAL PARK, Wyo. – A geologist says some parts of the continually shifting, collapsed volcano at the center of the park are swelling unusually fast.

Bob Smith, one of the leading researchers into Yellowstone's geology, presented some of his findings at the American Geological Union meeting in San Francisco this week.

Smith and other geologists from the University of Utah are particularly interested in two subterranean lava domes deep beneath the Yellowstone caldera.


"We've gone to this really pronounced, and I would say unprecedented, uplift of the caldera," he said.

But he said any talk of an eruption would be far-fetched.
