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. Operations at the state's public health laboratory were halted as the building is assessed for damage, the state Department of Health said. "I know the last thing we need right now is an earthquake, but here we are, and it sounds like aftershocks are likely," Salt Lake City Mayor Erin Mendenhall said on Twitter.
