A small earthquake rumbled through west Salt Lake County at 7:40 p.m. on Friday, but only a few residents reported sensing the shaker.

Walter Arabaz, director of the University of Utah Seismograph Stations, said the temblor measured 2.0 on the Richter scale.The quake was centered in the northern end of West Valley City at 21st South, about five miles east of Magna.

"This shock this evening was in the general vicinity of the West Valley Fault," Arabaz said. The zone is a series "of small faults for which there is considerable debate as to whether that fault zone is somehow connected to the Wasatch Fault Zone or behaves independently."

No damage was reported in the quake that the seismologist said "should be barely at the level of perceptibility."

"It's just a gentle reminder," he said. "It just would be so terrific if all of our earthquakes were conversation pieces."
