A magnitude 8.0 quake would hit Southern California with a force up to 32 times greater than the 1989 Loma Prieta tremblor in the Bay Area. Vital energy, gas and water conduits stretched across the San Andreas fault would be destroyed, leaving millions without critical, life-sustaining supplies for weeks. Many hospitals that haven't been retrofitted to survive a mega-scale quake, would be severely damaged and unable to handle mass casualties. Thousands would die and tens of thousands would be left homeless as the infrastructure of Los Angeles buckled.
