Anyone know what the city of L.A. is built on? Apparently, earthquakes travel rapidly through rock and slowly (doing more damage) through sand. So depending on size of the quake it eventually gets, it could really be devastating. Also, depending on what the quake takes out in the way of infrastructure: freeways, rails and even water, we could be in for a world of hurt because we would not be getting any deliveries unless we start shipping them by boat or flying them in (assuming the runways are not damaged.
