During January 2014, the University of Utah reports 157 earthquakes were located in the Yellowstone National Park region. The largest earthquake was a minor event of magnitude 3.5 on January 6, 2013 at 2:14:39 AM MST, located about 5 miles west northwest of Norris Geyser Basin, YNP. This earthquake was part of a small swarm of 63 earthquakes that occurred from January 6-9, with continuing activity on the 18-23. An additional small swarm of 13 events occurred January 10-16, with magnitudes 1.2 to 3.4, located about 10 miles east northeast of Norris Geyser Basin, YNP.

Yellowstone earthquake activity in January remains at a relatively low background level.

Current deformation patterns at Yellowstone remain within historical norms.

Please see: for a map of GPS stations in the Yellowstone vicinity. For a graph of daily GPS positions at White Lake, within the Yellowstone caldera, please see: 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.
