// Strategic Significance
San Francisco International is built on fill in San Francisco Bay and sits directly on bay mud subject to liquefaction in a major earthquake. The runways extend over the bay with serious sea level rise and storm surge vulnerability. The 1989 Loma Prieta earthquake severely impacted the airport.
// Civilian Impact Assessment
57 million annual passengers. Bay mud liquefaction in a major earthquake could make runways unusable. The bay location creates serious sea level rise vulnerability as the airport sits only feet above high tide.
// Evacuation & Shelter Guidance
US-101, I-380, Millbrae Avenue. San Mateo County Emergency Management coordinates seismic and flooding protocols.
