The West Thumb of Yellowstone Lake |
- In April 2004 there was an increase in earthquake activity, called a swarm, at Yellowstone National Park that drew interest from scientists and the public. Swarms can occur on volcanoes or in tectonically active areas and there have been many swarms recorded over the past 40 years at Yellowstone.

- New Fact Sheet--
Tracking Changes in Yellowstone's Restless Volcanic System-- describes
recent work of scientists to monitor changes in the land surface
elevation within Yellowstone Caldera, an enormous basin created 640,000
years ago in a great volcanic eruption. In the 1970s, scientists
discovered that there had been over two feet of vertical uplift in the
caldera since 1923, and began leveling surveys to accurately measure
recent uplift. During the past ten years scientists have been applying
new satellite-based surveying techniques, including GPS and radar
measurements, for an increased understanding of the slow up and down
ground movements of the Yellowstone caldera above the subterranean magma
and hydrothermal systems.
