What key geological factors must be evaluated when selecting a pipeline route across seismically active areas?

When selecting a pipeline route across seismically active areas, several key geological factors must be carefully evaluated to minimize the risk of pipeline damage or failure during an earthquake. First, identifying and avoiding active faults is paramount. Active faults are geological fractures in the Earth's crust that have moved recently and are likely to move again, causing ground rupture directly beneath the pipeline, which can lead to immediate failure. Mapping these faults and establishing buffer zones is crucial. Second, soil conditions are critical. Areas with liquefiable soils (loose, saturated soils that lose stren....
