The pipeline was built to withstand earthquakes , forest fires , and other natural disasters . The 2002 Denali earthquake damaged some of the pipeline sliders designed to absorb similar quakes , and it caused the pipeline to shut down for more than 66 hours as a precaution . In 2004 , wildfires overran portions of the pipeline , but it was not damaged and did not shut down
