Historically, Idaho experiences a large earthquake about every 20 years, according to the Idaho Bureau of Disaster Services. Next Tuesday, Oct. 28, marks the 20-year anniversary of the Borah peak earthquake, Idaho’s largest recorded tremor.
At 7.0 on the Richter Scale, the Borah Peak earthquake was seismically significant, and it caused more property damage than any other temblor in the state’s history. It killed two children in Challis and inflicted approximately $12.5 million in damage in Challis, Mackay and areas in between.
"When it hit, it was like a clap of thunder or a sonic boom," a U.S. Forest Service spokesman told reporters following the quake.
