Where the Denali fault crossed the trans-Alaska pipeline, dislocation occurred along a series of en echelon fissures resulting in 5.5 meters of right-lateral offset and 0.6 meters of up-to-the-north vertical displacement. Strong shaking and movement of the pipe resulted in damage to 8 horizontal support members, and 9 anchored supports near the fault crossing. These affects were not critical to the integrity of the pipeline, which performed well during the event.
