SALT LAKE CITY -- The Utah Geological Survey has been busy digging holes, trying to find more information on the frequency of large past earthquakes along the Wasatch Fault Line.

So when will the next big earthquake strike the Wasatch Front metro area? "When we look at the most active part of the fault, these earthquakes occur about every 300 years. The most recent large earthquake on the Wasatch Fault occurred about 350 years ago near Nephi," said DuRoss.

Overall, DuRoss says a large earthquake is due. "So in the Wasatch the safe thing to say is that one of these earthquakes could occur at any time," he said.
