Is CA next? CA Earthquake Info / Predictions


Cities have been rebuilt on top of a secretly-replaced water system. Complete failure to protect public health or maintain compliance issues and/or appropriate safety factors. Public records altered to cover up the evidence of this operation. To fully understand the danger we have already been unknowingly been put in, as well as the potential dangers we are facing, see photos and information. Click: Marla

CA is experiencing an increase in earthquakes. Just recently:

Northern CA had another earthquake Jan. 8, 2010. 6.5 magnitude in Ferndale.

A 5.9 quake occurred east of San Diego on December 31, 2009.

Rather than continuing with this list, let's look ahead, to what is expected to occur in the central valley.

This is a portion of info from the County of Fresno:

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."

Earthquake Shaking Potential, Central Valley (Delta) Area

Most residents of the Central Valley, including the Delta region, are familiar with the occasional “roll” of a Bay Area earthquake. However, few know that there are actually earthquake-producing faults that underlie the valley sediments below them. These faults have been deeply buried by sediments deposited by flooding rivers since they last ruptured. Included in this group is a buried fault that in 1892 produced a strong (estimated M6.6) earthquake centered in the Vacaville-Winters area, where significant damage occurred. Other poorly defined faults in the Central Valley include the Midland, Sweitzer, Dunigan Hills, and Willows faults, along with what’s generally referred to as the San Joaquin fault zone, which is made up of numerous buried faults extending along the western margin of the Great Valley.

Because we cannot yet clearly define the locations of most faults buried beneath the valley floor, it is impossible to calculate what ground motions are likely to be produced if they were to rupture. However, we do know that the shaking can be significantly damaging as indicated by the 1892 Vacaville-Winters earthquake and the 1983 Coalinga earthquake (M6.5).

Central Valley (Delta) Area
Epicenters and Faults

The underlying fact is that residents of the Central Valley ShakeOut Area are not immune to the damaging impacts of strong earthquakes and, therefore, should take preventative measures to prevent injuries to themselves and loved ones, as well as minimize damage to their homes, businesses, and communities. Of particular concern is how vulnerable the Delta levees are to earthquake shaking. A strong earthquake centered in or adjacent to the Delta region could cause widespread levee failure, which, in turn, would likely disrupt or terminate water supplies to agricultural and metropolitan areas throughout the central valley and southern California region; curtail local farming; and significantly impact the Delta eco-system.

California has strict building codes that are designed to prevent structures from collapse, and events like the Nov. 13 ShakeOut teach individuals what to do in an emergency.

A factual, well-researched book of earthquake & tsunami disasters in California, with an in-depth analysis of fault behaviors & explanation of where & when the next great earthquake will be. By George Pararas-Carayannis, Ph.D.

Millions of California residents live near one of the most seismic regions in the world, the San Andreas fault. In 1989, the Loma Prieta earthquake was devastating. In 1994 the Northridge earthquake was terribly disastrous. However, neither of these earthquakes will compare to the next catastrophic earthquake due to strike California in a matter of a few years, OR SOONER.

Probabilistic Seismic Hazard Map

A probabilistic seismic hazard map is a map that shows the hazard from earthquakes that geologists and seismologists agree could occur in California. It is probabilistic in the sense that the analysis takes into consideration the uncertainties in the size and location of earthquakes and the resulting ground motions that can affect a particular site.
The maps are typically expressed in terms of probability of exceeding a certain ground motion. For example, the 10% probability of exceedance in 50 years maps depict an annual probability of 1 in 475 of being exceeded each year. This level of ground shaking has been used for designing buildings in high seismic areas. The maps for 10% probability of exceedance in 50 years show ground motions that we do not think will be exceeded in the next 50 years. In fact, there is a 90% chance that these ground motions will NOT be exceeded. This probability level allows engineers to design buildings for larger ground motions than what we think will occur during a 50-year interval, which will make buildings safer than if they were only designed for the ground motions that we expect to occur in the next 50 years.

The California Strong Motion Instrumentation Program (CSMIP) records the strong shaking of the ground and in structures during earthquakes throughout California. The measured ground strong shaking is used immediately after an event to assist in emergency response by agencies like OES. Structural measurements are studied after events to analyze the performance of structures, with the goal of mitigating future earthquake impacts through improved building codes for safer, more earthquake resistant structures.

All this talk of building codes, earthquake protections laws, etc. is serving to give us a false sense of security. Behind the smokescreen there were no permits, inspections or safety precautions used for the unauthorized reconstruction on top of the secretly-replaced water system. Virtually no enforcement of building standards / regulations.

Can you imagine what is going to happen when an earthquake reaches these areas? Where entire cities have been rebuilt on top of clamped sewer and water lines as shown below?

Whereas other cities are showing great concern and preparing residents for such occurences, the City of Fresno (where the core of this operation is located) refuses to address the situation - including their own unaltered records, which verify exactly what is taking place!



Earthquake drills have been taking place in CA. See my blog with various articles supporting predictions for CA's "Big One." This is also where you will learn the shocking truth about compliance issues and Earthquake standards in the central valley, specifically, the secrets that various (Fresno) city officials do not want the public to know about.

In the meantime, the article below compares the similarities between Haiti's Enriqwuillo-Plaintain Garden fault and CA's San Andreas fault.

(CNN) -- Scientists have warned for years that the island of Hispaniola, which Haiti shares with the Dominican Republic, was at risk for a major earthquake.
Five scientists presented a paper during the 18th Caribbean Geological Conference in March 2008 in Santo Domingo, Dominican Republic, stating that a fault zone on the south side of the island posed "a major seismic hazard."

Tuesday's potentially disastrous 7.0 earthquake occurred in Haiti along the same fault line, known as the Enriquillo-Plantain Garden fault zone.


The Enriquillo-Plaintain Garden fault is similar in structure and character to the San Andreas fault of California in that both are strike-slip in nature, meaning the plates move past each other in a horizontal direction, Mann said.

Thursday's drill was based on a scenario of a magnitude-7.8 earthquake occurring along the southern San Andreas Fault, beginning at the Salton Sea and spreading north nearly 200 miles.

"It's not a matter of if an earthquake of this size will happen, but when," the Great Southern California ShakeOut's Web site says.

Officials hope the earthquake drill will prepare residents for the big quake, whenever it may hit. "From a geologist's point of view, the answer has to be soon," Kate Hutton, a seismologist at the California Institute of Technology, said in July, referring to a large temblor.

Under the central part of the San Andreas fault, the deep seismic whisperings known as tremors have increased after two recent large earthquakes, and a surge in tremors appears to have foreshadowed one of them, according to a study to be published today in the journal Science.

"It reaffirms the need to be ready," said Robert Nadeau, a research seismologist at UC Berkeley who led the study. "The San Andreas fault is changing down deep and it's changing down deep in places where large earthquakes have happened in the past."
