2 days after people, The Trans-Alaska Pipeline is an oil pipeline that carries oil from Alaska’s North Slope to holding tanks in Valdez. If laid out in the lower 48 it would stretch from Dallas to Chicago. There is 380 million gallons of oil inside the pipeline at any given time. As the pipeline’s pump station run out of fuel they shut down and oil stops flowing through the pipeline.
200 years after people, Due to the cold climate the pipeline has corroded slowly. The supports of the Trans-Alaska Pipeline were designed to withstand earthquakes and even though the pipeline’s supports have corroded slowly they have still corroded enough to be vulnerable. Finally an earthquake shakes the pipeline, the supports fail and the pipeline collapses. The remains of the pipeline could last for over 2000 years due to the low corrosion rate.
