Borah Peak Scarp:
More than 6 feet was added to this fault scarp by vertical movement in the 1983 Borah Peak, Idaho, earthquake (magnitude 7.3). Because the region affected was sparsely populated, the earthquake caused only two deaths and about $10 million of damage. An earthquake of similar magnitude on the Wasatch Fault in Utah would affect heavily populated urban areas and could have much more severe consequences.
