A loud “boom” reported by numerous residents throughout northern Utah early Saturday was likely a meteor, officials said. 

The “boom” was heard around northern Utah and in parts of southern Idaho around 8:30 a.m. Saturday. The noise was so loud, the University of Utah’s seismograph monitoring department reported some people felt the “boom,” causing concerns of an earthquake.

“We can confirm that it was not an earthquake,” the department said on Twitter. 

Utah Gov. Spencer Cox tweeted he heard the noise while on a morning run in Salt Lake City, adding the noise didn’t come from nearby military instillations. 

The noise was captured on home security cameras, and some shared footage with audio on social media. One resident was left wondering, “What was that?” 

South Salt Lake resident Wendi Melling was heading out the door Saturday morning when she heard the noise, which she described to the Salt Lake Tribune as a “loud deep booming sound” followed by a few seconds of rumbling.

“I thought I heard something fall in the house,” Melling wrote in a Facebook message to the outlet.

“It did sound similar to sonic booms I’ve heard before, followed by a short incident of a sound similar to low rolling thunder,” Melling continued. “This rumbling noise that followed the boom was maybe on 3-4 seconds.”

Amid the confusion, the National Weather Service seemed to find the answer. They tweeted their Geostationary Lightning Mapper, which can detect lightning in clouds, spotted a signature north of Salt Lake City that wasn’t part of a thunderstorm.

The service tweeted it was likely a meteor’s trail or flash, “bolstering the meteor theory.”
