Aftershocks are likely, according to Utah Emergency Management.

SALT LAKE CITY — A major earthquake rocked Salt Lake City early Wednesday morning.

The quake hit just after 7 a.m. on the west side of the city, just north of the town of Magna. According to USGS, the earthquake was recorded as a 5.7 magnitude.

Utah Emergency Management says the quake was felt from Logan to Riverton in Utah, with the strongest shaking felt in Salt Lake City itself.

Power has been knocked out to more than 55,000 people in the area. Rocky Mountain Power said in a tweet that crews are assessing the damage and working to get electricity restored as fast as possible. It's not yet clear whether anyone was hurt.

The earthquake marks the strongest quake to hit Utah since 1992, when a 5.9-magnitude earthquake rattled St. George.

Aftershocks are likely Wednesday, according to Utah Emergency Management. Check back for updates.

Utah Gov. Gary Herbert is asking everyone to stay away from downtown Salt Lake City while emergency responders work.

The Salt Lake City Airport "is not currently operational," according to the airport. The FAA tower, terminals, and concourses have been evacuated, and the road to the airport has been reopened so passengers can be picked up.

Planes headed to Salt Lake City now are being diverted to other airports. All flights into Salt Lake City from the Boise Airport and other airports around the country are listed as delayed, and will likely be canceled.

The earthquake also damaged Utah's state lab and forced the evacuation of the Poison Control Center. Utah's coronavirus hotline is currently down, Herbert said.

The Utah Department of Health said the inspection of the lab building will be prioritized, and they will resume laboratory operations as soon as they are able. A COVID-19 press conference scheduled for Wednesday afternoon has been canceled.
