Support Beam   Trans-Alaska Pipeline at the Denali Fault on extended support beams (to allow for movement) http://earthquake.usgs.gov/eqinthenews/2002/uslbbl/photos/pr071102/new/PICT0072.JPG •  Earthquake magnitude pipeline was designed to withstand 8.5 Richter Scale (maximum). Range from 5.5 to 8.5, depending on area.   •  Three Faults crossed by pipeline ---  Denali         McGinnis Glacier         Donnelly Dome   •  The predicted limit of lateral movement(side-to-side) for above ground pipeline, general 2 ft.   •  Maximum values for pipeline movement at major faults   Denali fault — 20 ft. lateral and 5 ft. vertical displacement McGinnis Glacier fault — 8 ft. lateral and 6 ft. vertical displacement Donnelly Dome fault — 3 ft. lateral and 10 ft. vertical displacement Minor potential fault locations — 2 ft. lateral and 2 ft. vertical   Click on Arrow to Return to Structural Component Diagram
