YVO Brings on New Member Organizations
January 14, 2013
Beginning in 2013, YVO officially welcomes several groups that have been important informal partners to the observatory for many years. Along with the USGS, Yellowstone National Park, and the University of Utah, YVO now includes the three state geological surveys of Wyoming, Montana and Idaho, UNAVCO, Inc., and the University of Wyoming. The seismic network will continue to be operated by the University of Utah. More information about the YVO Consortium is available on the About YVO page.
Taking the Temperature of Yellowstone from Space
June 08, 2012
We all know Yellowstone is hot… but how hot? And how can we detect park- or basin-wide changes in geothermal areas (regions that let off Earth’s internal heat) that may take place over months, or years? USGS geologist Greg Vaughan and other YVO colleagues recently studied Yellowstone’s thermal areas by looking at satellite-based remote sensing data from two NASA satellites. Using satellites that orbit around Earth to measure heat released from Yellowstone's hottest regions produced results that are similar ground-based measurements. Therefore, these space-based remote sensing methods can save time and assist in determining changes in thermal areas that may be too remote to access on foot. Vaughan and others published their findings in the July 2012 issue of the Journal of Volcanology and Geothermal Research. For more information, read the web article Taking the Temperature of Yellowstone from Space.
