Tsunami "wave"

Artist conception of California's "Big One".

I'm still thinking about the earthquake in the Indian Ocean on Dec. 26. It made the entire planet vibrate and triggered devastating tsunamis through the area killing between 230,000–280,000 in 14 countries and triggered other earthquakes as far away as Alaska.  Until now, I did not realize just how powerful they can be. It got me thinking about the proverbial "Big One" that's been predicted for California for decades.

When I lived in San Francisco, I worried about it a lot. The quake in SE Asian is a shocking reminder of just how vulnerable coastal cities are. I found this photo shopped image of California's proverbial Big One. Chilling.
