Witnesses said it started as a rolling rumble that quickly dissolved into the sound of breaking glass and falling bricks.
Official sources differ as to how powerful it was. The United States Geological Survey marked it as 5.9 on the Richter scale. The University of Utah’s Intermountain Seismic Belt Historical Earthquake Project calls it a 5.7, similar to the one that hit the Salt Lake Valley in March of 2020.
But that’s about the only thing the two have in common.
