During the month of December 2012, the University of Utah reports 94 earthquakes were located in the Yellowstone National Park region with a notable increase of earthquake swarms. The largest earthquake was a magnitude 2.6 event on December 15, 2012, at 6:25 AM MST, located about 10 miles north of Pahaska Teepee, WY. Dec. 9 through Dec. 10 a small swarm of 11 events was located 9 miles north northwest of West Yellowstone, MT with magnitudes 0.3 to 2.1. On Dec. 13 a small swarm of 12 quakes was recorded about 13 miles east of Old Faithful, YNP with magnitudes 0.3 to 2.1. Also on Dec. 13 a small swarm of 12 quakes was recorded between Lewis and Shoshone Lakes with magnitudes 1.4 to 2.5. Overall Yellowstone earthquake rates are normal for this monthly reporting period.

Slow subsidence of the caldera, which began in early 2010, continues. Current deformation patterns at Yellowstone are well within historical norms.
