The
Fremont Earthquake Exhibit
on the Hayward Fault
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.”
