TOOELE — Seismologists at the University of Utah are calling Saturday night's earthquake a "minor" event.

About 9:30 p.m., a 3.2 magnitude quake, centered about five miles northeast of Tooele, was felt widely throughout the Tooele Valley, Magna and some other parts of the Salt Lake Valley. There were no reports of damage or injuries.

Keith Koper, director of the University of Utah Seismograph Station, said the interesting thing about Saturday's earthquake was that there had not been any aftershocks as of Sunday afternoon.

"This one just seemed to come all on its own. Just one event. It doesn't really have too much to do with the likelihood of future earthquakes," he said.

Saturday's quake was considered a "shallow earthquake" since it was triggered approximately four miles underground, he said.

The last earthquake recorded by the U Seismograph Station was a 3.5 magnitude quake on April 4 near Gunlock.

Saturday's quake also comes two days after Utah participated in the Great Utah Shakeout, an event designed to promote preparedness for earthquake survival and recovery.
