SALT LAKE CITY — The strongest earthquake to hit Utah in 28 years rocked the state just after 7 a.m. Wednesday.

The U.S. Geological Survey initially reported the 5.7 magnitude quake hit just northeast of Magna about 7:09 a.m.

No deaths have been reported as a result of the earthquake, Salt Lake County Mayor Jenny Wilson said in a news conference. Various gas leaks and instances of building damage have been reported, she said.

You can watch the news conference at the 10:55 mark below:

A second 3.7 magnitude aftershock hit about 7:15 a.m., according to the USGS, and another 3.5 magnitude aftershock hit shortly thereafter. Dozens of aftershocks happened throughout the day, the largest being a 4.6 magnitude that hit shortly after 1 p.m.

Rumors of a bigger earthquake coming later Wednesday are untrue, according to Utah emergency officials. In 95% of earthquakes, the first quake is the strongest, according to the Utah Division of Emergency Management.

Salt Lake County officials are currently asking people to stay off the roads and stay home if possible.
