YELLOWSTONE VOLCANO OBSERVATORY MONTHLY UPDATE
Monday, April 2, 2012 11:45 AM MDT (Monday, April 2, 2012 17:45 UTC)
YELLOWSTONE VOLCANO (CAVW #1205-01-)
44°25'48" N 110°40'12" W, Summit Elevation 9203 ft (2805 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN
During the month of March 2012, the University of Utah reports 51 earthquakes were located in the Yellowstone National Park region. The largest was a magnitude 2.3 event on March 3 at 6:02 PM MST, located about 20 miles west northwest of West Yellowstone, MT A small swarm of 10 events was recorded on March 3 about 10 miles northwest of West Yellowstone, MT with magnitudes ranging from M 2.1 to M 0.7
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.

Their results paint a new picture of a more active volcano than previously thought and can help recalibrate the likelihood of another big eruption in the future. Before the researchers split the one eruption into two, it was the fourth largest known to science.
The new ages for each Huckleberry Ridge eruption reduce the volume of the first event to 2,200 cubic kilometers, roughly 12 percent less than previously thought. A second eruption of 290 cubic kilometers took place more than 6,000 years later.
Magnitude 4.5
