TRANS-ALASKA OIL PIPELINE SURVIVES A M 7.9 EARTHQUAKE |
| Caption: |
Right: In its construction, the Alaskan oil pipeline was designed to withstand several meters of horizontal displacement where it crossed the Denali fault south of Fairbanks. That design was put to the test in 2002 when it shifted horizontally 4.3 m (14 ft.) during the M 7.9 Denali Fault earthquake. Built-in bends of the pipeline on slider beams with teflon shoes accommodated the earthquake rupture as designed. This was strong confirmation of the importance of estimating potential ground rupture and taking action to mitigate it. [Alyeska Pipeline Service Company (ASPC)] |
