February 3, 1994 – Draney Peak, ID – M 5.9
A magnitude 5.9 earthquake occurred approximately 10 miles west of Afton, Wyoming at 2:05 a.m. on Thursday, February 3, 1994.
The earthquake was felt in parts of four states: Idaho, Wyoming, Utah and Colorado. The strongest shaking was reported felt in and around the Star Valley, Wyoming area. Other cities where shaking was felt included: Pocatello, Soda Springs and Montpelier, Idaho; Jackson, Wyoming; Salt Lake City and Moab, Utah; and Grand Junction, Colorado.
Reports from Afton, Wyoming, noted that the earthquake was accompanied by a loud roaring sound. Heavy furniture and large appliances were moved by the shaking. Lamps overturned, items fell from shelves and pictures from walls. Some private water wells were muddied in Star Valley, Wyoming. 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.
No deaths or major injuries were reported for this earthquake.
