About 700 earthquakes happen in Utah every year, although only about 2 percent of these are felt. They can happen anywhere in the state of Utah, not just along the Wasatch Front.

Large earthquakes between a magnitude of 6.5 to 7.5 can happen at active segments of the Wasatch fault between the areas of Brigham City and Levan.

Over the past 6,000 years, a large earthquake has occured about every 400 years.

Close to 600 years have passed since the last large earthquake happened in Utah Valley. It has been almost 1400 years since the last large earthquake happened in the Salt Lake Valley.
