Subject: Great leap forward in ground motion Date: Tue, 06 Jun 2000 10:56:45 -0600 From: Edward CranswickTo: zoback@........ Mary Lou- Your excellent presentation yesterday about new approaches to ground motion data acquisition -- particularly the idea of a 3-d accelerometer on every PC CPU chip -- contained the most innovative and pro-active notions about the ways the community can sense the Earth that I have heard in the last decade. I am interested to see where you go with this enthusiasm. -Edward -- Edward Cranswick Tel: 303-273-8609 US Geological Survey, MS 966 Fax: 303-273-8600 PO Box 25046, Federal Center cranswick@........

Hi all, Thought I would pass along the following info I sent to Jim Davis (CA State Geologist) and Dick McCarthy (Exec Director, CA State Seismic Safety Commission). As most of you know, we have been working with these guys (and others) to push through a CA state bill to support earthquake studies to the tune of $15-20M/year. Part of these $$ would go to monitoring and could respresent a significant CA cost-share for ANSS (~$6M/yr). In trying to sell this bill, there has always been the question of what is the state paying for, or why does the state need to pay if the feds will do it? As explained below, I think we may have a hook that would represent clear benefit to the state and which they might be interested in funding--one could easily imagine all sorts of colateral educational benefits. What do you think? cheers, Mary Lou Hi Jim and Dick, At Assemblywoman Ellen Corbett's invitation, I spoke last Friday at a public hearing she held in Hayward on Eq Safety and Preparedness in CA schools. I was asked to speak about eq probabilities on the Hayward, but I broadened my talk to the entire Bay area with a focus on Hayward--to make the point that no place is safe and that eqs on other faults could profoundly affect the East Bay. The night before a thought occurred to me--that this would be a good group to float a proposal to. As it turned out, only Ellen Corbett came and a staffer for Assemblyman Dutra--so I did not get the attention of the full committee. The audience was primarily composed of Emergency Respnse coordinators and Risk Managers for various East Bay school districts. I wanted to let both of you know about the state "initiative" I proposed. It may sound like something competing with our current eq monitoring request, or it may be a clever way to sell monitoring $$ to the state legislature. I began by planting the idea that with dramatic increases in digital technology and telecommunications over the past 10 years, not to mention the Internet, we have an opportunity to raise a whole generation of Californians who are aware of earthquakes and earthquake hazards by harnessing the power of the web (SHakeMap, Community Internet Intensity Map, etc). I ended the talk with the following proposal with bulleted benefits (simply one transparency): CA Schools Seismic Station Initiative- a real-time, Internet-connected strong motion station in every school * Educate kids and parents about eq hazards-- I explained that the kids could take "ownership" of their station, they could use the internet to view the data recorded by their station, learn how their station contributes to making a "ShakeMap" after any felt earthquake, and learn that not all earthquakes are large and destructive, some are small and not even felt). This could create many "teachable moments" in the schools and fundamentally integrate earth science as part of the core science curriculum. * Determine sensitivity of school site to shaking-- I briefly tried to explain how scientists could use numerous small earthquakes as proxies for larger ones and learn about the sites susceptibility to shaking. This could help promote the role of geology in determining shaking levels and lead to discussions about how different rocks form. * Provide real-time notification of potential damage for parents-- I suggested that based on the recorded level of shaking at the school, an asssesment of likely damage could be made immediately and posted on the web, this way parents could logon to their schools' site and get the information. With structural engineers we could establish a red, yellow, green system for each school. Another value of such monitoring is that in many communities schools are designated as emergency sites and temporary shelters *****************NOTE: I didn't mention with this group that this would be a way to greatly densify our coverage in urban areas and would go a long way toward getting a station in every zip code--that would not have sold to this audience. It occurs to me that maybe this may be a way to sell the state on eq monitoring. A station in every school would certainly address OES' needs, it would make it clear what the state was buying and getting, and all the collateral education benefits could be really played up. For example, maybe the Cal State system schools could adopt nearby schools and have students visit the schools to educate teachers and students about their seismograph station and eqs in general. Another potential twist would be to get the local communities involved in cost-share, corporations could sponsor schools' stations, Kiwanis Club could help raise funds, etc. Seems like CDMG would be the ideal group to adminster such a program. What do you think? cheers, Mary Lou ___________________________________________________________________________ Dr. Mary Lou Zoback, Chief Scientist OFFICE: 650-329-4760 Western Region Earthquake Hazards Team FAX: 650-329-5163 U.S. Geological Survey CELL: 650-868-2332 345 Middlefield Rd.
