We felt some earthquake last month as well. Huge damage to some cities, it seems that our world is going a little uneasy.
We definitely worry about that here in San Diego, Us. At least I do all the time. 4% chance of a 9.0 or greater hitting in the next 20 years and we are 50 miles from an aging nuclear plant that sits on the ocean. 50% chance of a really big one (forget the richter scale # but a very significant, serious one) in the next 20 years.
