WASATCH FRONT, Utah (ABC 4 News) - A B-52 Stratofortress bomber aircraft flying from Barksdale, Louisiana caused the great rumble over portions of Utah and Wyoming when it dropped bombs in a training center west of the Great Salt Lake.

The rumblings were heard and felt from Sandy all the way to Rock Springs, Wyoming Tuesday night at 9:00 p.m.

The first rumbling lasted about five seconds and the second rumbling, which came about two minutes later, lasted about four seconds. 

The training exercise included dropping bombs west of the Great Salt Lake.  The concussion produced sound waves so low they could not be detected by the human ear, but they were powerful enough to rattle windows and shake homes.

University of Utah Seismologist Katherine Whidden says the inversion played a roll in the rumblings across the Wasatch Front.  She says the particles in the air can direct the sound waves toward the ground with greater force. 

A spokesperson for Hill Air Force Base wrote in a news release, the inversion can amplify the waves as they travel creating a more powerful sound even at greater distances. 

Rumbles will be felt across Utah Wednesday night around 9:00 p.m. as another B-52 Stratofortress bomber completes a similar test run.
