The U.S. Geological Survey said the 5.7-magnitude earthquake was reported just after 7 a.m., with an epicenter located three miles north-northeast of Magna, and it occurred at a depth of six miles. The temblor and its aftershocks rattled a region of approximately 2.8 million people who are already hunkered down amid the coronavirus epidemic.
“This is extremely bad timing, because we already have the coronavirus issue going on right now causing a lot of anxiety,” Gov. Gary Herbert said at a news conference.
Herbert said the temblor was "felt across much of the state," urging residents to follow proper safety measures in the event of any additional aftershocks or quakes.
"Please stay away from the downtown area while crews assess damage," Herbert tweeted. "Unless you work in public safety, or are an essential employee, remain at home or telework."
The governor added the Utah Department of Health's state lab is assessing damage and is "currently down."
"The poison control center has been evacuated and the @UtahCoronavirus hotline is down," Herbert said.
Capt. Anthony Burton of the Salt Lake City Fire Department told Fox News while the quake was centered about 10 to 15 miles west of Salt Lake City, the temblor was "pretty strong" in the city.
Burton, a 13-year veteran of the department, told Fox News he has never felt an earthquake this strong in Salt Lake City. He added the fire department is currently doing a survey now of damage and that there were some reports of gas leaks.
There were no initial reports of major damage to buildings or injuries, Utah Emergency Management spokesman Joe Dougherty told the Associated Press. As many as nine buildings in Magna were damaged in the quake, FOX13 reported.
Operations at Salt Lake City International Airport came to a halt and the control tower and concourses were evacuated, the airport tweeted. The road to the Salt Lake International Airport was closed and officials asked people not to head to the airport.
No runway damage was found following the inspection and most of the damage in the terminal appeared to be caused by a broken water line. The airport's executive director, Bill Wyatt he expected the airport to reopen in “hours not days."
The quake also shut down the light rail service for Salt Lake City and its suburbs. Residents reported feeling shaking across a 100-mile area, with the heaviest impact in Salt Lake County, officials said.
People were left asking “What the hell was that?” in one video posted to Twitter.
Some residents ran from their homes and into the streets as they felt the earthquake shake buildings for 10 to 15 seconds.
The Church of Jesus Christ of Latter-day Saints told FOX13 the Salt Lake Temple, which is undergoing a seismic upgrade, sustained some minor damage during Wednesday morning’s earthquake.
"The trumpet on the Angel Moroni statue fell off, and there is minor displacement of some of the temple’s smaller spire stones. No workers were injured," the church said. Crews on the job site have been sent home for the day, and a full assessment is underway to determine needs going forward."
The quake knocked pictures from walls and dishes from shelves, and people reported feeling it in the neighboring states of Colorado, Idaho, Wyoming, and Nevada. About 70,000 people lost electricity in the Salt Lake City area, said utility Rocky Mountain Power.
It was the largest earthquake to hit Utah since a 5.9 magnitude quake shook southern Utah in 1992, according to Utah Emergency Management.
Most shaking was reported in the Salt Lake County area, near the epicenter in the Salt Lake City suburb of Magna but the quake was felt 80 miles away in the Utah city of Logan.
After the initial quake struck at 7:09 am, the geological survey recorded four smaller quakes over the next 23 minutes, ranging in magnitude from 3.7 to 3.9.
