MAGNA — A small earthquake rattled some residents out of bed early Wednesday.

The 2.8-magnitude quake hit about 2 a.m., mainly in the Magna area. More than 100 people reported feeling it to the U.S. Geological Survey's Web site.

There were no reports of damage or injuries. The majority of residents who reported feeling it were from Magna and West Valley City, according to the Web site.

"It was quite a small event," said seismologist Relu Burlacu from the University of Utah Seismograph Stations.

Burlacu said there have been small earthquakes in that area before. The most significant was a 5.2 quake in 1962.

More studies will be conducted to determine which fault line generated Wednesday's quake, he said.
