I read "The Really Big One" first, then "Hollister." They were both good articles. I can't say I was terrified or freaked out. Maybe I am deadened to crises since there have been so many of them.
I was freaked out because, while I myself have never endured a life-threatening crisis firsthand, I did have many friends who lived in New Orleans during Katrina and I endured a close-call hurricane while i lived there and I've known towns around here get struck by tornadoes now and then -- including, on Saturday, the hometown of a former best friend -- and of course, there's the odd blizzard and so on.
But this described a crisis that would dwarf those, that would be far worse than the Japanese tsunami and for which the area is far less prepared. When it said (quoting from memory) "Of all natural disasters, a tsunami offers the least chance of survival" or talked about how, once the earthquake devastated your big city and entire coastline, your problems had only just started, because once the shaking stopped, you'd have less than 10 minutes to get your shit together enough to run like hell for your life -- disregarding the lives (the article implied, though of course I could never totally do this) of anyone else, including your family members -- but that you probably wouldn't make it anyway and would immediately find yourself under 100 feet of water floating amid submerged semis and the like ... well, yes, I found that fairly freaky. Give me a blizzard any day. Even a hurricane.
And what I found most astounding of all is how few people have ever even heard this was a problem. I know I hadn't.
