Ground Deformation Summary: Continuous GPS data show that uplift of the Yellowstone Caldera has slowed significantly and have have stopped in some
areas. The WLWY station, located in the northeastern part of the caldera, underwent a total of ~23 cm of uplift between mid-2004 and mid-2009. Its
record can be found at:

The general uplift and subsidence of the Yellowstone caldera is of scientific importance and will continue to be monitored closely by YVO staff.

The Yellowstone Volcano Observatory (YVO) is a partnership of the U.S. Geological Survey (USGS), Yellowstone National Park, and University of Utah to
strengthen the long-term monitoring of volcanic and earthquake unrest in the Yellowstone National Park region. Yellowstone is the site of the largest
and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories
that monitor volcanoes within the United States for science and public safety.
