you're talking about, if it -- the big one that you're talking about, if it does get that series of small quake, you're talking about 8.1 on the richter scale for the quake? >> it could, if the whole southern half of the san andreas fault went, it could produce an 8.1 magnitude earthquake. jon: we saw what an earthquake of that magnitude did in haiti. obviously haiti does not have the building codes we have in this country and it only exacerbated the damage. >> that's right. jon: you're telling people to get prepared. how do you get prepared for an 8.1? >> we know in california we have an earthquake problem and we started, in 2008, we started this exercise called the great shakeout, do it once a year, this year is coming up on october 21st at 10:21 in the morning. onjon we'll get information on our website for people who want to look into that. lisa, thank you very much.
