how prepared is California for the "Big One" I was in Los Angeles during the recent 5.4 earthquake and it got me asking - how prepared is California for the "Big One" that's supposed to come soon? Also, I've heard that cities like Chicago and NY are also at risk for high-magnitude earthquakes, even though it may not seem like it. How prepared are those cities, at the moment, for such catastrophes? I mean, what kind of buildings would be at risk? What about in cities like Seattle, Sydney, Auckland, and HK?
