Earthquake Swarm Strikes Yellowstone*

YELLOWSTONE NATIONAL PARK, Wyo. Sixteen small earthquakes with
magnitudes up to 2.7 shook the park's Pitchstone Plateau last week.

The quakes were detected by seismographs at the University of Utah and
partners.

Bob Smith, a University of Utah professor, says the quakes began
Monday, just before midnight. The largest occurred at 3:09 a.m. Tuesday
and the quakes continued until Wednesday

The quakes occurred on the southern edge of a volcano caldera at the
center of Yellowstone. The volcano last erupted 70,000 years ago.

Smith says earthquake swarms are common in Yellowstone. As many as 70
swarms of small earthquakes have occurred in the region between 1983 and
2006.
