SALT LAKE CITY — Hundreds of people from Weber County to Utah County, and some as far north as Rock Springs, Wyoming reported that they felt shaking or heard loud booms Tuesday night around 9 p.m.
The FOX 13 Newsroom received several calls from concerned citizens about the phenomena shortly after 9 p.m., but the cause remains a mystery.
Experts at the seismology department at the University of Utah confirmed there was seismic activity measured just behind the Capitol building.
“There are low-frequency signals that are usually from the atmosphere. The infra-sound network is most sensitive to signals that come from the atmosphere, so we think this was an above ground event,” said Katherine Whidden, research seismologist. “These can be airplanes that are breaking the sound barrier, they can be explosions or they can be storms.”
Representatives for the University of Utah’s Seismograph stations said there was not an earthquake, ATK said they were not conducting any rocket tests, the Utah National Guard said they were not conducting any weapons or artillery training and Hill Air Force Base said they did not have any planes in the air after 6 p.m.
A map of earthquakes over the last day shows no activity in Northern Utah, or anywhere in the state. The closest quake was a relatively small 2.6 magnitude near Bishop, Calif., more than 500 miles from Salt Lake City.
