<p><b>New page</b></p><div>==Task Overview==<br />
<br />
===Objective===<br />
The potential for soil liquefaction, slope failures, and damage to buried pipelines is assessed in this task.<br />
<br />
===Purpose===<br />
The purpose is to determine if SSCs on the SEL are subject to soil failure modes.<br />
<br />
===Guidance===<br />
For most plants, a review based on design and construction records is considered adequate to screen out these types of failures. A detailed analysis is needed only if soil failure is deemed significant. This task is usually carried out by specialist geotechnical engineers. To the extent that soil failures may impact plant structures housing PRA components, this task should be performed early in the assessment. The structures and components of interest are provided by the output from the SEL ([[Develop Seismic Equipment List (Task 2)]]).<br />
