During the month of November 2011, 51 earthquakes were located in the Yellowstone National Park region. The largest was a magnitude 3.0 event on November 28 at 11:02 AM MST, located about 7 miles west southwest of Old Faithful, YNP. No swarms were recorded in November.
Yellowstone earthquake activity continues at relatively low background levels.
Slow subsidence of the caldera, which began in early 2010, continues. Current deformation patterns at Yellowstone are well within historical norms.
