SALT LAKE CITY, Utah – A 5.7 magnitude earthquake shook Utah's Salt Lake City area Wednesday morning, cutting power to tens of thousands and suspending work at the state's public health lab amid the coronavirus pandemic, officials said.

Flights to Salt Lake International Airport were being diverted, departures were postponed, and terminals and concourses were evacuated as workers inspected runways, the airport and the Federal Aviation Administration said.

The quake was centered about 10 miles west of Salt Lake City and near the city of Magna, starting at 7:09 a.m. MT, the US Geological Survey said.

This is the state's most powerful quake since 1992, when a magnitude 5.9 temblor struck the St. George area, Utah's Division of Emergency Management said.

Operations at the state's public health laboratory were halted as the building is assessed for damage, the state Department of Health said. The state's coronavirus hotline, which residents may call to request tests and seek information, was down after the quake, Gov. Gary Herbert said on Twitter.

More than 47,000 customers in the area were without power after the quake, Rocky Mountain Power's website reported.

"Please stay away from the downtown area while crews assess damage," Herbert said. "Unless you work in public safety, or are an essential employee, remain at home or telework."

The quake comes as Utah residents, like people across the world, are adjusting to changes brought by the coronavirus pandemic, including canceling schools and limiting mass gatherings.
