Major Quake hitting Los Angeles knocking out servies for three days would decimate the region for years to come. Five days and the State would never recover, Seven days and the nation would suffer catastrophically, 10 days and the world would slip into a depression. I don't know if those stats still hold 15 years later.
That is very interesting information. I maintained a low profile, but obviously, much can happen. The US is a large part of the world economy, so your research figures right in there. A major California quake will be felt world wide in more ways than one.
