NEW RESEARCH, RESULTS, and/or PROJECTS
New Research:
In an upcoming USGS Professional Paper entitled History of surface displacements at the Yellowstone caldera, Wyoming, from leveling surveys and InSAR observations, 1923–2008, Dan Dzurisin, Mike Poland, and Chuck Wicks discuss the historical record of ground deformation at Yellowstone and its likely causes. The report: (1) summarizes knowledge about Yellowstone's eruptive history, magmatic system, and hydrothermal system, particularly as those topics pertain to the interpretation of ground deformation measurements; (2) describes the history of leveling and InSAR observations at Yellowstone, as well as other evidence for paleo- and contemporary ground deformation; (3) discusses the evolution of thought concerning the mechanisms of ground deformation at Yellowstone; and (4) provides an archive of information concerning more than 500 geodetic bench marks in Yellowstone National Park. It is expected to be available in hardcopy and on the Web by the end of 2011.
In a related effort, the authors deployed six temporary GPS stations in Yellowstone National Park during summer 2008 and nine such stations during the summers of 2009 and 2010. The temporary stations complement the permanent GPS networks operated by the Plate Boundary Observatory (PBO, http://pboweb.unavco.org/) and the Yellowstone Volcano Observatory (YVO, http://volcanoes.usgs.gov/yvo/). Time-series plots for more than 120 GPS stations in or near the Park are available at:
