    Tyson Lagoon has been a site of fresh water for at least the last 3700 years. This sag pond outlines the trace of the Hayward fault zone in this area. Observations of brittle deformation and liquefaction features in trenches just north of this area indicate there may have been 6-8 large earthquakes during the last 2000 years. Lienkaemper, et al, with new data concluded that since late 1300's there were probably four large earthquakes (of magnitude 6.8-7.0) In trenches in the South Pond they found evidence of the 1868 earthquake. The earthquake destroyed most of the Mission Adobe structure and devastated the homes of many of the residents. Using detailed stratigraphy and carbon dating they arrived at dates of 1730, 1630, and 1470 (±90 years) for the other earthquake occurrences. The Tule Ponds at Tyson Lagoon Wetland Center under the guidance of the Math Science Nucleus and Alameda County Flood Control District, has opened this 14-acre facility to celebrate not only its rich geologic past but to act as a facility that shows how urban life can coexist with nature areas. This is one of several sites that the Math/Science Nucleus is developing in the Fremont area. More information on the Tyson Lagoon site and others in the east bay can be found at:

    Joyce Blueford

    Dr. Joyce Blueford received her undergraduate degree from U.C. Berkeley and Ph.D. from U.C. Santa Cruz. She worked 14 years at U.S. Geological Survey in Menlo Park. She founded and is President of the Math Science Nucleus (, a non profit science research and education organization. As a geologist, Dr. Joyce Blueford has distinguished herself in the field of radiolarian micropaleontology and sedimentology in California, Alaska, the Russian Far East, and Siberian Platform. She had written over 30 papers, including editing eight scientific books. As an educator, she has designed numerous classes in geology and science education. She has written six volumes of curriculum, which are used around the world. She started a non-profit, Math/Science Nucleus which is devoted to increasing science to children throughout the world. She has been the lead researcher on several projects including the integration of pen computers into schools and the use of Internet technology to create a new medium of electronic textbooks. She currently is working on establishing the Integrating Science, Math, and Technology Program in the African country of Eritrea.

    Reservations: The preferred way to make reservations is simply to email Janice Sellers at by March 12, tell her you will attend, commit to pay, and bring your payment to the meeting. Janice always emails a confirmation; if you don't get one, assume email crashed yet again and email her a second time. A check made to "PGS" is preferred, payable at the meeting.

    If you want to pay in advance:

    Stanford faculty and students: Please make dinner reservations by March 12. Contact Dr. Juhn Liou via his mailbox (and leave check), Geological and Environmental Sciences Office, Geocorner - Bldg. 320 (Rm. 118). Make checks out to "PGS."

    All others, including faculty and students from other Bay Area universities and colleges and USGS: Please make dinner reservations by March 12. Contact Janice Sellers, at Seismological Society of America, 201 Plaza Professional Building, El Cerrito, CA 94530, phone (510) 559-1780. Send check made out to "PGS" to Janice.

    Dinner is $30.00. Includes wine (5:30 to 6:15 PM.), dinner (6:15-7:30 PM.), tax, and tip.

    For students from all universities and colleges, the dinner, including the social 3/4-hour, is $5.00 and is partially subsidized thanks to the School of Earth Sciences, Stanford University (Note, no-show reservations owe the full price).

    Doris, whose wonderful crew prepares our meals, asked that we let you know that people who are late RSVP'ing and people who show up without a reservation will be welcome but that they will be eating on paper plates with plastic utensils (food supply permitting).

    Dues for Academic Year 2003-2004 ($10.00) should be sent to Janice Sellers, Seismological Society of America, 201 Plaza Professional Building, El Cerrito, CA 94530. Janice's phone: (510) 559-1780.
