Updates on Yellowstone activity
During the month of April 2011, 91 earthquakes were located in the Yellowstone National Park region. The largest was a magnitude 2.2 event on April 13 at 7:11 AM MDT, located about 15 miles southeast of West Thumb, YNP. A small swarm of 24 earthquakes was recorded on April 14, located about 5 miles east of West Thumb, YNP, with magnitudes ranging from M 2.0 to M -0.1.
The period of caldera uplift that began in 2004 ended about one year ago. Since then, the caldera has been subsiding, though seasonal deformation from ground water changes may temporarily mask the trend. (USGS)
