Seismic Hazard Along a Central U.S. Oil Pipeline

by Howard H. M. Hwang, Memphis State Univ, Memphis, United States,



Document Type: Proceeding Paper

Part of: Lifeline Earthquake Engineering in the Central and Eastern U.S.

Abstract:

An integrated approach is used to evaluate seismic hazards at six sites where pipeline 22 crosses the major rivers in West Tennessee. On the basis of historical and instrumental data, a recurrence relationship for the New Madrid seismic zone is established. Then, the seismic hazard curves for these six sites are developed by using the ground motion attenuation relationship proposed by Nuttli and Herrmann. In addition, the hazard-consistent magnitude and hazard-consistent distance corresponding to a specified annual probability of exceedance are determined to establish the ground motion such as earthquake acceleration time histories of a probability-based scenario earthquake. These acceleration time histories can then be used for evaluating soil liquefaction potential at a site and seismic vulnerability of lifeline facilities.
