The Hayward Fault
an Educational Experience
 joint project with Math Science Nucleus, City of Fremont, U.S. Geological Survey, California Geological Survery

150th Anniversary of the Great Quake of 1868
Grand Opening of Earthquake Walk on the Hayward Fault

Sunday, October 21  (11- 4 pm)
Where:  Central Park (Lake Elizabeth), 450 acre park in the heart of Fremont (several locations, see map)


The Hayward Fault has shaped the landscape of the East Bay for the last million years.  The last large earthquake was on October 21, 1968, when a 6 foot offset was ripped from Milpitas to San Leandro.  In certain places there was an uplift of 4-6 feet.  Hayward, San Leandro, Oakland and San Francisco had major damage.  Fremont’s Mission San Jose crumpled.   This one day event is to educate the public on the earthquake science, history, and preparedness.  The emphasis will be the Hayward Fault, but there will general information on earthquakes, other faults in the San Fransico Bay Area, and plate tectonics. There will be 3 focus zones throughout Central Park.  You will be able to walk to the different areas to see the new signs throughout the park.  


Kids Earthquake Zone:  The Fremont Community Center, 40204 Paseo Padre Parkway
     Families can learn through hands-on experiments how earthquake travel through the crust of the Earth and cause problems.  Learn the basic principles of Plate Tectonics and Engineering.  Children from 4-10 years will be able to build houses of blocks and see them tumble down; play earthquake games; color informative pages on temblors; see a San Francisco Bay Area fault map; pick out things they should take in case of an earthquake emergency; see a simulated quake in action; and much more.


Earthquake Science Zones:   There will be three sites that people can ask scientists and educators about the science behind the Hayward Fault.  We will publish which scientist will be at the different stations.  Many of them are responsible for our basic understanding.  

      A. Fremont Earthquake Exhibit.  See the "Faulted Floor" where 60 years of "creep" along the Hayward Fault can be seen.  Teen Center Area
     B. Senior Center Area (Moving Parking Lot) - See how the Hayward Fault has moved large areas in one direction.  You also will be able to see fault traces throughout the parking lot.  Learn about the rising "compression ridge" and why it happens.
     C.  Teen Center Area (En Echelon Fractures; 9000 Years of Movement) Learn about the large trench in the area that provided information of 150 feet of movement in 9000 years.  See offset curbs and asphalt.


Earthquake Preparedness Zone: At the Senior Center Parking Lot (Moving Parking Lot) to  Lake Elizabeth there will be different organizations to provide information on not only how to prepare, but also about insurance and how that all works.  We will publish a list of partipants closer to the event. 

Parents and adults will be able to bring home a wealth of information on how best to prepare for earthquakes and enjoy some interesting exhibits. The U.S. Geological Survey called our own Hayward Fault the most likely to be the source of the Bay Area’s next big quake with a one-in-three chance of a magnitude 6.7 rupture in the next 30 years. The admonition “Be Prepared” has never been so important.

Come see the "Faulted Floor" Exhibit.  See a map of the East Bay and where the Hayward Fault is ripping it apart.  For more information on the Faulted Floor Exhibit which is a permanent exhibit click here.

MATH SCIENCE NUCLEUS since 1982 has served the education and public by offering quality science and math lessons that take our children learn critical thinking skills. We manage the Children's Natural History Museum and Tule Ponds at Tyson Lagoon Wetland Center.

CITY OF FREMONT is located in the southeast San Francisco Bay area and straddling both the East Bay and South Bay regions.  It has a population of close to 1/4 million people and one of the largest city by land in San Francisco Bay area.   
U.S. GEOLOGICAL SURVEY is a government agency that Federal source for science about the Earth, its natural and living resources, natural hazards, and the environment.  They provide the posters and map for the Faulted Floor Exhibit.
CALIFORNIA GEOLOGICAL SURVEY was established in 1860, and one of the oldest geological surveys in the United States, serving as a primary source of geologic information for California’s government agencies, businesses, and public.
