Could Los Angeles withstand a 'megaquake'?

Carrying these results over to the worst-case scenarios for Los Angeles, this suggest that almost all buildings could become uninhabitable and still satisfy the definition of success for the building code

Transportation, gas and electricity supplies, sewerage systems, water supplies and communications would all be affected.
Whether a modern civic society could operate under such conditions is questionable. At the instant of the USGS model earthquake, debris would close roads, extinguish traffic lights, water supplies would be cut off, and emergency responders would have difficulty operating.
Beyond that, the disruption of the supply chain also becomes an issue, pointed out Dr Jones. The move towards a "just in time" economy in grocery stores and elsewhere has introduced additional vulnerability.
