Earthquake Awareness -  Grant from Alameda County District 1, Dave Haubert
OPEN HOUSE - Free to the public  October 21, 2023 


The field trip starts at the Fremont Earthquake Exhibit (back part of the Fremont Community Center) on Paseo Padre and Mission View.  Students will see a crack through the foundation and look at about 1.5 inches of offset.  We discuss the Hayward Fault and other information appropriate to audience.   The trip continues outside to walk about 1 mile to see the various "clues" in which the earthquake fault is outlined.  Included are up to 3 inches of offset. 

Participants will never look at cracks in the street the same way.  En enchelon patterns and offsets can be seen throughout Central Park in Fremont.  We will visit the site of the former City Hall that was taken down because it was built in the wrong location.  We will discuss how the County Main Library was built to take care of a possible shaker.

The tour was designed by Dr. Joyce Blueford, a geologist, who incorporates history of the east bay and discusses how the faults are responsible for our present landscape.   Each grade has different emphasis from more historical (3rd grade) to scientific (college).  Look at the "Walk" to see specific information at each station.

Since the tour is at Fremont's Central Park,there are picnic tables and bathrooms that you can use for your class and make an enjoyable and educational day.


The Hayward Fault is a major fault of concern in the East Bay.  It has been considered the most dangerous area for a possible major seismic event by the U.S. Geological Survey.  There is a one in three chance of a major earthquake of 6.8 or greater on the Hayward Fault within the next 30 years.   The last major quake in this area was on October 21, 1868, with a magnitude of 7.0, which ripped almost a continuous shear of about 6 feet from Milpitas to Oakland.

The City of Fremont was incorporated in 1956.  Unknowingly they built their first building, the Fremont Community Center on the Hayward Fault.  Within 10 years they noticed that the floor was cracking.  They first thought that it was only due to poor construction but then they realized there was an offset to a set of cracks.  After 10 years they had to close this area to the public, closing down a Children’s Theater.   Over the years it has grown into a 1-2 inches of offset.

The Math Science Nucleus in collaboration with the City of Fremont and the U.S. Geological Survey have created a “Faulted Floor” exhibit to be part of a general earthquake trail tour throughout Central Park.  There are currently two tours.  One through Fremont Recreation Department that includes a walk through Central Park (click here for more information) and a more scientific and longer walk  from Tule Ponds at Tyson Lagoon to the exhibit showing natural earthquake features (sag ponds, fault scarps) and urban features (offset curbs, moving of asphalt, compression ridges) in Central Park (contact Math Science Nucleus  msn@msnucleus to arrange dates).  Both include the "Faulted Floor." 

This City of Fremont walled off 600 square feet including walls to help us dramatize the science of earthquakes.  The facility will be used for field trips for K-college by the Math Science Nucleus.  The City of Fremont will also use the area when there are events in the park so people can look at the exhibit to learn the science behind earthquakes as well as learn about earthquake preparedness.  Volunteers and staff from the Math Science Nucleus will conduct the tours.

the U. S. Geological Survey to create a large map of the East Bay.  Visitors will be able to locate their house in relationship to the fault while stepping over the “crack.”

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.
     Math Science Nucleus received partial funding from PGE for the Faulted Floor Exhibit.
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.

4-ESS2.B:  Plate Tectonics and Large-Scale System Interactions
The locations of mountain ranges, deep ocean trenches, ocean floor structures, earthquakes, and volcanoes occur in patterns. Most earthquakes and volcanoes occur in bands that are often along the boundaries between continents and oceans. Major mountain chains form inside continents or near their edges. Maps can help locate the different land and water features areas of Earth. (4-ESS2-2)

4-ESS3.B:  Natural Hazards
A variety of hazards result from natural processes (e.g., earthquakes, tsunamis, volcanic eruptions). Humans cannot eliminate the hazards but can take steps to reduce their impacts. (4-ESS3-2)

MS-ESS2.B: Plate Tectonics and Large-Scale System Interactions
Maps of ancient land and water patterns, based on investigations of rocks and fossils, make clear how Earth’s plates have moved great distances, collided, and spread apart. (MS-ESS2-3)
