The USGS estimates that the San Fernando Valley would experience relatively low levels of shaking, while the Coachella, San Bernardino, Antelope and San Gabriel valleys would experience high levels of shaking. Shaking along the Cajon pass would disrupt utilities such as power lines, gas pipes, oil pipelines, fiber optic cables, and railroads.
“We are in a very aggressive campaign now, getting as many county residents as we can… signed up for the ShakeOut drill,” said County Supervisor Brad Mitzelfelt. “The 400,000 people that I represent who live on the other side of this fault will very likely be cut off from the rest of Southern California and we need to train in that scenario… not only to repair the damage but… to get back to normal life after that,” Mitzelfelt added.
USGS Geophysicist and Earthquake Designer Kenneth Hudnut said that a large earthquake could occur soon if past statistics are anything to go by.

Preparing for “Earthquake Katrina” & Levee Disaster in CAPORTION OF (4/30/07) ARTICLE BELOW:
In a scenario aptly dubbed “Earthquake Katrina,” the region will more likely than not experience a 6.7 magnitude – or greater – earthquake in the next few decades. The Delta’s levees are not designed to withstand a major flood, much less a major earthquake. A sudden levee failure of that extent would have serious impacts on the Delta ecosystem, already strained under the pressure of urban and agricultural resource demands, in addition to threatening human lives and property and disrupting water supplies and the state economy for months or years.
The Department of Water Resources estimates that levee damage due to an earthquake of this magnitude would require at least 15 months of repairs (realistically, much longer), flood as many as 85,000 acres of agricultural land and 3000 homes, and disrupt water and natural gas deliveries, shipping and transportation, with total costs to California’s economy in the range of $30 to 40 billion in the first five years.

SEISMIC & GEOLOGICAL HAZARDS
Fresno County’s General Plan Update
February 2000
These 12 pages describe how Fresno could be affected by earthquakes and related seismic hazards. It describes the active and potentially active faults within and adjacent to Fresno County. Ground shaking is the primary seismic hazard. Settlement of groundwater and physical rearrangement. Settlement of sufficient magnitude causes significant structural damage.
The State of California provides standards for building design through the CA Uniform Building Code (CUBC) and has been modified for CA conditions and numerous more detailed and/or stringent regulations. The State Earthquake protection law (CA Health & Safety Code 19100 et seq) requires that buildings be designed to resist stresses produced by lateral forces caused by wind and earthquakes. Installation of underground utility lines must comply with industry standards specific to the type of utility (e.g., National Clay Pipe Institute for sewers and American Water Works Assn. for water lines.) These standards contain specifications for installation and design.
Fresno County Grading Ordinance (Section 7001, March 1991) stipulates safety and environmental measures for construction practices. It is probable that Fresno will be affected by at least one moderate to large earthquake during the 20-yr timeframe of the General Plan. Broken water supplies and sewer lines are a major concern. (We are now approaching yr 9 of the predicted 20 yrs)
