March 26, 2002 - A workshop will be held April 2 - 4, 2002, to review the status of scientific studies of Yellowstone National
Park's active systems: those that produce earthquakes, molten rock and volcanism, and hydrothermal features such as geysers.

The meeting will be held at the Salt Lake City Marriott University Park Hotel. News media are invited to cover the sessions, which
run 8:30 a.m. to 5:30 p.m. April 2 and 3, and 8:30 a.m. to 12:30 p.m. April 4. The meeting is not open to the general public.

The workshop is sponsored by the Yellowstone Volcano Observatory (YVO), which was established in May 2001 by the U.S. Geological
Survey, Yellowstone National Park and the University of Utah. The observatory's creation formalized ongoing efforts to monitor
earthquakes, gradual ground deformation and volcanic, magmatic and hydrothermal activity in the Yellowstone region.

Known as the YVO First Science Review, the workshop's general theme is "Active Processes in the Yellowstone Tectonothermal System."
More than 50 people have been invited, and there will be more than 30 scientific presentations.
