Where the fault crossed the trans-Alaska pipeline, dislocation occurred
along a series of en echelon fissures. One of these en echelon breaks
intersected the end of one of the Teflon surfaced skids (sleepers) that
supports the pipe in the fault zone, displacing it about a meter but not
damaging the pipe.

Strong shaking and movement of the pipe resulted in damage to 8 horizontal support members, and 9 anchored supports near the fault crossing. These effects were not critical to the integrity of the pipeline, which performed well during the event.
