I will be interested in seeing the recorded ground motions from this latest quake.
Hospital designs we've been doing in the past decade CA are supposed to withstand about 7+ richter tremblors. Some are now thinking that structural seismic requirements should be upped again to deal with eathquakes in magnitudes recently felt in Japan (8+).....Many are also worried about tsunami damage for coastal facilities (and theres lots of it in CA), after seeing what it did in Japan. I don't think that is even adressed in any way yet these days........ Next thing you know, we'll be doing designs that will withstand the sun going supernova on us or a mile wide asteriod hitting the planet??!
