YELLOWSTONE VOLCANO (CAVW#1205-01-)

NOVEMBER 2007 Yellowstone Seismicity Summary
During the month of November 2007, 69 earthquakes were located in the Yellowstone Region. The largest of these shocks was a magnitude 2.9 on November 4, 2007 at 11:43 PM MDT, located about 2 miles south southeast of West Thumb, WY. This earthquake was slightly felt at West Thumb and Old Faithful but produced no damage. There were no earthquake swarms during the month.
Earthquake activity in the Yellowstone region is at relatively low background levels.
Ground Deformation Summary: Through November 2007, continuous GPS data show that most of the Yellowstone caldera continued moving upward at similar to slightly lower rates as the past year. The maximum measured ground uplift over the past 37 months is ~17 cm at the White Lake GPS station. An example can be found at: http://pboweb.unavco.org/shared/scripts/stations/?checkkey=WLWY&sec=timeseries_plots×eries=raw
The general uplift of the Yellowstone caldera is scientifically interesting 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.
