The YVO webcam is offline temporarily. We hope to get it up and running soon. Please be aware that the camera runs via a solar panel and cellular modem. Unlike most similar cameras, it does not have connection to either AC power or the internet. In the interim, here's a nice image from the camera taken the last week that the camera was operational.
USGS scientist Phil Dawson and colleagues have applied a novel research approach to voice recognition software. In their January 2012 paper, published in Geophysical Research Letters, they utilize this software to discover that background seismic activity in geyser basins can be intimately linked to daily cycles of heating and cooling. For more information read the web article in the Yellowstone volcano earthquake monitoring section.
Recent telemetry problems, from ice and snow buildup on data transmission antennas, have caused intermittent malfunctions of the University of Utah's automated earthquake location system. The malfunctions result in false earthquake reports, which upon review, are then manually deleted from the earthquake catalog. The snow and ice buildup interferes with the continuous streaming of seismic data causing occasional signal dropouts. The dropouts cause spikes to appear in the data streams, which the automated system misinterprets as the abrupt appearance of a high amplitude seismic wave from an earthquake. Windy conditions, common this time of year, exacerbate the problem by contributing additional noise and thereby reducing the overall signal quality of the seismic data streams. In most cases, seismologists at the University of Utah can overcome these problems and still identify and locate earthquakes correctly. Seismic activity at Yellowstone remains at background levels.

Beginning October 1, 2010, the University of Utah Seismograph Stations has reduced the threshold from M 2.5 to M 1.5 for automated plotting of earthquakes for the Yellowstone region. For more information please see the UUSS announcement. See today's earthquake map.
A report, "Protocols for Geologic Hazards Response by the Yellowstone Volcano Observatory," has just been published. The document summarizes the protocols and tools that the Yellowstone Volcano Observatory (YVO) will now use during earthquakes, hydrothermal explosions, or other geological activity that could lead to a volcanic eruption. This USGS circular was written by an inter-organizational group of scientists, land managers, and emergency responders that met in November 2008 in Bozeman, Montana.
YVO has finished installing a series of radio-equipped temperature sensors to document changes in water flow and heat discharge in the Norris Geyser Basin. Daily, weekly, and monthly temperature plots are now available from our new monitoring page, "Taking the Temperature of the Norris Geyser Basin."
Geysers are rare hot springs that periodically erupt bursts of steam and hot water. Yellowstone National Park has more than half of the world's geysers. Old Faithful has remained faithful for at least the past 135 years, showering appreciative tourists every 50 to 95 minutes (most recently an annual average of 91 minutes). To view Old Faithful in real-time, see the National Park Service Old Faithful Webcam.
There were were notable changes in thermal activity at Norris Geyser Basin in 2003. These changes resulted in the closure of the Back Basin Trail and temporarydeployment of a monitoring network by YVO. Learn more.
