As fascinating as the history of Yellowstone volcano is, however, most professional geologists who study the site are not concerned that the park is on the brink of a catastrophic eruption. The bulge on the bottom of the lake may have been there for thousands of years, but not noticed until the recent survey. Changes in the geyser activity is not unusual. New geysers have appeared throughout the history of the park, while others go dormant. Rangers often shut down parts of trails or alter them as needed.
The land near the center of the caldera did rise more than three feet between 1923 and 1985. However, between 1985 and 1992 it actually subsided six inches. Studies of the shorelines of Yellowstone Lake have led scientists to believe this is a regular phenomenon. The caldera floor has risen and fallen at least three times in the last 10,000 years, moving as far as 65 feet.
The idea that Yellowstone may be "overdue" is also faulty. With only three catastrophic eruptions and two intervals between to go on there is not enough data to say that another one should be occurring in the near future.
