The most telling comparison I saw was damage done in S. California from a 7th or 8th mag quake that lasted for seconds. Interstate Bridges collapsed along with other extensive damage in an area "prepared" for quakes. The shaking in Japan lasted several minutes, this type of quake would devastate S. California, or any urban area for that matter. They also mentioned that the Nuclear Power plants were not designed to withstand an earthquake of this magnitude. How confident are you that S California N Plants are built to withstand any magnitude of earthquake that is possible? The one proposed for Green River? Cost evidently trumps safety.
This is mildly off topic but does talk about crustal tides and earthquake
predictions.
I don't know much about this guy but what he is saying may provide for an interesting discussion.
