Saint Louis Missouri sits directly above the New Madrid Seismic Zone — one of the most dangerous earthquake fault systems in North America. A major New Madrid event could produce shaking far more destructive than anything experienced on the West Coast, with soil liquefaction along the Mississippi River threatening bridges, pipelines, and the city water system. Saint Louis also faces significant flooding risk along the confluence of the Missouri and Mississippi rivers. The city hosts major chemical and industrial facilities along its riverfront corridor and is a critical rail and barge transportation hub for the central United States.
