Hi, I partly reverted your addition on the Wasatch Fault article, so I thought that I owed you an explanation. It's true that the epicentre of the recent earthquake lies within the area of the surface traces of the West Valley Fault Zone, but at the depth of the earthquake (11.7 km) the west-dipping Wasatch Fault lies vertically beneath the earthquake's surface location - see the diagram on Page 1. The faults of the West Valley Zone dip down to the east and join with the Wasatch Fault well above the level of the earthquake. I hope that that helps.
