We present the analysis carried out to investigate the cause of a gas explosion that occurred in Minneapolis. A gas pipeline leaked, resulting in the explosion, and the objective of the analysis is to determine whether the leak resulted from failure of a water main existing below the pipeline, or from differential settlements causing the failure of couplers that connected sections of the pipeline. An analysis based on the theory for a beam on an elastic foundation makes the differential settlements the most likely cause of the explosion.
