Cluster of Quakes Hit Yellowstone

Scientists are closely monitoring Yellowstone National Park following a cluster of some 250 tremors. While "swarms" of earthquakes in the vicinity are nothing new, that many are; scientists are wondering if it is a sign of something bigger on the way.

A geophysics expert says one quake measured 3.8 - an earthquake measuring 4 on the Richter scale is severe enough to cause moderate damage. Of the cluster that occurred Monday, one measured 3.3, but most were "barely detectable."

In 1959, a 7.8 earthquake in the region triggered landslides which killed 28 people.
