      YELLOWSTONE VOLCANO OBSERVATORY MONTHLY UPDATE

      YELLOWSTONE VOLCANO (VNUM #325010)
      44°25’48” N 110°40’12” W, Summit Elevation 9203 ft (2805 m)

      Seismicity

      During September 2014, the University of Utah Seismograph Stations reports 71 earthquakes were located in the Yellowstone National Park (YNP) region. The largest event was a small earthquake of magnitude 3.2 on September 24, at 3:41 AM MDT, located about 9 miles south of Mammoth, YNP. There were no earthquake swarm sequences during the month of September.

      Yellowstone earthquake activity in September is at low background levels.

      Ground deformation

      Deformation in north-central Yellowstone continues, although the subsidence rate at the NRWY GPS station has slowed considerably. The total subsidence now comes close to matching the amount of uplift that had occurred previous to April 2014.

      Caldera GPS stations continue to record the pattern of uplift that has persisted since the beginning of 2014. An example can be found at: http://www.unavco.org/instrumentation/networks/status/pbo/data/HVWY (click on Static Plots / Time Series)

      The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity 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.
