MAGNA, Utah -- Another aftershock hit Salt Lake Valley Tuesday night, nearly four weeks after a 5.7 magnitude earthquake occurred near Magna.
The U.S. Geological Survey reports that a 4.2 magnitude aftershock hit at 8:56 p.m. The epicenter was 2.8 miles southwest of Magna.
University of Utah seismologists say it was the strongest of all 1,247 aftershocks since the March 18 quake.
Utah Division of Emergency Management spokesman Joe Dougherty says damage is unlikely, but crews will be out checking.
Dougherty also says aftershocks are normal and should not be surprising.

This aftershock is part of the Magna sequence and even though we have not felt shaking for a couple of weeks, the aftershocks are ongoing and this is normal.https://t.co/Rig14n3kPd
