The operators of the 800-mile long trans-Alaska pipeline said they shut the system down as a precaution following the earthquake in southcentral Alaska.
Michelle Egan is a spokeswoman with Alyeska Pipeline Service Company.
She says there is no known damage to the pipeline.
She says data will be assessed at an operations center and a physical inspection of the line will be performed.
Meanwhile, Alaska Airlines has suspended operations at the Anchorage airport until at least 12:30 p.m. Pacific.
The back-to-back earthquakes measured 7.0 and 5.8, rocking buildings and shattering roads.
The tsunami warning has been lifted.
