Some areas reported that their pets appeared to be upset by the earthquake.
In Utah’s Salt Lake Valley, the earthquake set off a number of burglar alarms. The Salt Lake City Dispatch Center was overwhelmed with calls seeking information, making it difficult to respond had there been calls reporting serious damage or injuries.
In the epicentral area, property damage included cracked foundations, structural shifting, damage to plaster walls and chimneys, broken windows, broken dishes and food bottles. A fish hatchery near Auburn, Wyoming reported that the earthquake shifted a support wall, causing the roof of the building to sag.
