mr. richter is selling it. we are going to put a plug in for cold hardware. they are not available. it's a rather complex. >> in fact we don't even use the richter scale anymore. we use a moment magnitude. the richter scale was early technology. >> probably a myth that i hear most often is my building is just fine in the loma prieta earthquake so everything is fine. is that true ? >> loma prieta was different. the ground acceleration here was quite moderate and the duration was moderate. so anyone that believes they survived a big earthquake and their building has been tested is sadly mistaken. >> we are planning for the bigger earthquake closer to san francisco and a fault totally independent. >> much stronger than the loma prieta earthquake. >> so people who were here in '89 they should say 3 times as strong and twice as long and that will give them more of an occasion of the earthquake we would have. 10 percent isn't really the threshold of damage. when you triple it you cross that line. it's much more damage in earthquake. >> i want to thank you, harvey, thanks pat for (music) >>
