AEG-CCGO joint meeting and CCGO Fundraiser
The California Council of Geoscience Organization's (CCGO’s) motto says it all; "An Advocate for the Profession in the
Public Interest." Membership dues, donations, and fundraisers are the means for funding CCGO’s expenses for the year.
CCGO is YOUR organization, representing YOU in Sacramento. CCGO represents both professional organizations like AEG,
AAPG, CGEA, and AWG, GRA and businesses employing engineering geologists, hydrogeologists, geophysicists, and other
geoscientists. Charles Nestle, CCGO vice president, will present a brief talk about CCGO and its recent activities and
accomplishments. The main presentation of the evening will follow.
Earthquake History Preserved in Tyson Lagoon: A New Environmental Wetland Center that Happens to be Right on the Hayward Fault!
Tyson Lagoon, a 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. New data compiled by Lienkaemper et al indicate that since the 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
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. As a geologist, Dr. Joyce Blueford distinguished herself in the field
of radiolarian micropaleontology and sedimentology in California, Alaska, the Russian Far East, and Siberian Platform.
She has written over 30 papers and edited eight scientific books, and as an educator she has designed numerous classes in
geology and science education. 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. She
founded and is President of the Math/Science Nucleus, a non profit science research and education organization devoted to
bringing science education to children throughout the world.
