During June 2016, the University of Utah Seismograph Stations, responsible for the operation and analysis of the Yellowstone Seismic Network, reports 70 earthquakes were located in the Yellowstone National Park (YNP) region. The largest event was a micro earthquake of magnitude 2.9 on June 30, 03:41 AM MDT, located 17 miles southwest of West Thumb, WY.
June 2016 seismicity did not include any earthquake swarms. Yellowstone earthquake activity in June is at low background levels.
Uplift at the Norris GPS station (NRWY), which began in early 2016, continues at a rate of ~5 cm/yr. The pattern of ground deformation in the Norris area resembles that observed from late 2013 through early 2014, although the present uplift rate is less than half of what it was before. Caldera GPS stations continue to record slow subsidence at a rate of ~1.5 cm/yr.
Current deformation patterns at Yellowstone remain within historical norms.

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.
