The San Andreas Fault is a massive tectonic boundary posing a severe threat to California. With stress building for nearly a century, experts warn that a major earthquake—potentially magnitude 8.0—is imminent. While cities like Los Angeles are implementing retrofitting measures, the potential for catastrophic casualties and economic damage remains high due to the region's geological vulnerability.
To the state of emergency in California,
where the governor is asking the White House for help.
7.1 magnitude earthquake has hit
Southern California in the studio here.
And it is going for quite a bit, everybody.
Southern California are keeping their eye on Imperial County tonight.
The San Andreas Fault is shown by the green line running
from the Salton Sea in the south to the
north for 800 miles through coastal and inland California.
The fault is known for cutting
California in half and causing devastating earthquakes
that keep the U.S. government
and Californians on edge. Recent discoveries suggest a worsening event.
When will the San Andreas fail?
Will California sink?
Scientists are rushing to find solutions before the big event.
Join us as we explore the scary signals
that the San Andreas Fault is poised to crack
and what that means for California and the world.
For Californians, the San Andreas Fault conjures images
of devastating earthquakes.
It's a massive crack in North America's west.
From the northern Gulf of California to San Francisco,
this fault runs northwest for over 800 miles.
The continual geological movement near its base,
which causes earthquakes, makes this fault so dreaded.
The 1906 earthquake still haunts Americans.
Five years after a minor earthquake in 1989,
One of the San Andreas' bigger secondary faults erupted
in the Los Angeles suburbs.
The fault line did not pass through
the impacted towns despite the devastation.
Some villages on the fault line are vulnerable to earthquakes.
Let's look at how the San Andreas crack is about
to cause the biggest tsunami in history.
Point Reyes Station, Frazier Park, Daly City,
Desert Hot Springs, Gorman, San Bernardino,
Wrightwood, Palmdale and Bodega Bay are vulnerable.
Every Californian was worried
when Southern California Earthquake Center Director Thomas
Jordan warned of the San Andreas Fault's catastrophic state.
Thomas says the fault line is critical
and might cause a catastrophic earthquake.
This new warning has worried Californians even more.
Thomas said the Southern California fault line looks locked,
loaded, and ready to go.
A magnitude 7.9 earthquake erupted 185 miles between Monterey County
and the San Gabriel Mountains near Los Angeles in 1857.
The San Andreas system springs are tight from too much silence.
The recent statement at the National Seismic Conference in Long Beach
has everyone on high alert,
wondering when and how severe the next earthquake will be.
Californians are rightly worried about the San Andreas Fault.
The Pacific Plate slowly moves northwest,
relative to the North American Plate
at this significant tectonic border.
This action should ease 16 feet of plate movement every 100 years.
Yet, stress has been building up for almost a century.
Thomas Jordan, director of the Southern California Earthquake Center,
has warned that the fault appears to be critical
and a major earthquake may be imminent.
This San Andreas Fault segment
is not the only one due for an earthquake.
San Bernardino County, southeast in the Cajon Pass,
has not shifted since an earthquake in 1812.
From 1680 to 1690, southeast towards the Salton Sea was peaceful.
Geologists found that the Pacific plate
is moving northwest of the North American plate,
compounding the issue.
Jordan recommends that California prepare for a magnitude 8 earthquake.
He commended Los Angeles for earthquake retrofitting apartments
and concrete structures.
San Bernardino County and other cities must follow suit
to become earthquake ready. Los Angeles
Mayor Eric Garcetti has been relentlessly preparing
the city for the worst earthquake scenario.
Thomas Jordan, director of the Southern California Earthquake Center,
praised his earthquake retrofits on apartment and concrete buildings.
Jordan was surprised
by this planned success, saying, wow,
these adjustments are politically tough.
Despite these efforts, California remains unprepared.
The state is facing one of its
worst natural calamities as the San Andreas Fault breaks.
According to the USGS, a magnitude 7.8
earthquake on the southern San Andreas
Fault may produce 50,000 injuries,
$200 billion in damage, and long-term interruptions.
Coachella Valley, Inland Empire,
and Antelope Valley residents could feel this tremendous
earthquake for approximately two minutes.
The San Gabriel Valley and East Los Angeles,
where sediments trap shaking waves, may experience significant shaking.
The sewer system might be
down for six months, causing 1,500 deaths.
To prepare for the worst, this situation is critical.
Strengthening Los Angeles' dangerous aqueduct
and telecommunication systems is another priority.
California must act quickly to reduce the damage
and deaths from a major tragedy.
The 1857 Fort Tejon quake shows
that the San Andreas Fault may wreak massive devastation.
This 7.9-magnitude earthquake,
which started in Monterey County and moved south past Fort
Tejon to the Cajon Pass in San Bernardino County, gained its name.
Soil liquefaction
and tree uprooting in Stockton occurred during
the one-to-three-minute tremor.
Despite running through Los Angeles,
the San Andreas Fault is 30 miles away from downtown.
This distance doesn't make the city safe.
Due to its proximity to the San Andreas Fault system,
a significant earthquake is predicted
to shake the city severely.
Thomas Jordan and his team produced a magnitude 7.8 fault quake
to show the devastation.
From the Salton Sea to the San Gabriel Mountains, the simulation
shows how seismic waves can influence Los Angeles.
Another simulation depicts earth
shaking from northern San Diego County to Barstow.
The Southern California Earthquake Center
Simulated a magnitude 8 San Andreas Fault earthquake
in 2010 using a supercomputer.
The simulation replicated the 1857 earthquake but was stronger.
Due to soft soil trapping vibration,
the LA Basin and San Fernando Valley are struck strongly.
Jordan says, You can see that this shaking region has extended
to tremendous dimensions.
The fault's directivity pulse excites sedimentary basins like
the San Fernando Valley, Los Angeles
Basin, and San Bernardino. Long-lasting shaking in Los Angeles.
What would we call the San Andreas Fault in the simulation?
Plate Tectonics states that the San Andreas Fault separates
the northern Pacific and North
American plates of the Earth's crust.
The strike-slip San Andreas Fault is caused by
the northern Pacific plate advancing northward past
the North American plate.
During the early 20th century,
plate movement has been 4 to 6 centimeters per year, while
geologic time has seen 1 centimeter per year.
With such activity, the next big one is imminent.
The 1906 San Andreas Fault earthquake caused some portions
to move 6.4 meters.
Others still call the San Andreas a transform fault,
but knowing this can be confusing.
Imagine two pizza slices on a table, one pepperoni and one anchovy.
Pepperoni crumbles onto the anchovy side as they slide past each other.
The fault does this,
making the rift's geology and landforms complicated and unpredictable.
Despite its risk, tectonic plates move only
a couple of inches every year, around the same
rate as your fingernails. This action isn't constant.
Sometimes, the plates lock together
and don't move. This reduces motion to a few inches every year.
When the strain ultimately
breaks the rock along the fault,
the plates can abruptly slip several feet, sending out earthquake
waves in all directions. The San Andreas Fault
is more than an undetectable crack in Earth's crust.
It's visible in portions of California.
Visit the Carrizo Plain in San Luis Obispo County
to see this powerful fault.
Marin County has the fault's scarps and pressure ridges.
Some areas of the fault are hidden by brush
and alluvium or haven't moved in years.
In cities like Los Angeles and San Bernardino,
roadways cut through mountains of fine, powdery,
crushed rock from moving plates.
The San Andreas Fault is a 30 million year old geological masterpiece.
Rocks from different places have been driven together
by plate movement and collision,
generating a diversified rock type on both sides of the fault.
The Salenian block of granite
in central northern California came from southern California,
and the Neenock volcanoes in Los Angeles County
are the other half of a volcanic complex
that begins 200 miles southeast in Monterey County.
The San Andreas Fault is a tribute to tectonic activity
and nature's beauty, regardless of whether it's in North Mexico.
Several San Andreas Fault myths and stories are untrue.
The fault can create big earthquakes,
although mega-quakes of magnitude 10 or higher are fiction.
Scientists found no flaw long enough
to cause such a big earthquake.
The San Andreas Fault, while substantial at 880 miles long,
is not quite long enough to create an earthquake of this size.
The fault length determines earthquake magnitudes.
Hence, longer faults cause stronger earthquakes.
On a nearly 1,000-mile fault in Chile,
the biggest earthquake ever recorded was 9.5.
Predicting earthquakes is another fallacy.
Scientists are working hard to forecast earthquakes,
but there is no reliable way to predict
their time, place, and magnitude.
We're researching it, but it's not yet possible.
Finally, while the San Andreas Fault
is unlikely to generate a megaquake,
the San Francisco Bay Area
and Southern California are at risk of a big earthquake.
Experts estimate a 60% chance of a major earthquake
in these places within 30 years.
With an earthquake, you must know the hazards and take precautions.
Scientists can now anticipate earthquake ground motion despite
the San Andreas Fault's unpredictability.
Engineers and building code developers need
this information to make structures earthquake-resistant.
Due to its proximity to California's vast population
and infrastructure,
Experts remain concerned about the San Andreas Fault.
Nevertheless, nature lovers can enjoy exploring the fault.
The fault has several quiet routes for family vacations,
camping, birdwatching, and rock collection.
Like beads in a thread, state and national parks along
the fault offer breathtaking views of wildflowers and wildlife.
Scientists and geologists are still unsure
when the fault will release its stress.
San Andreas earthquakes are notoriously devastating.
Everyone wonders if the next
one will be as powerful as the 1857 Fort Tejon earthquake
or the 1906 San Francisco earthquake.
The San Francisco earthquake leveled structures and killed hundreds.
The Great Fort Tejon earthquake,
felt through Southern California, was the largest.
Parkfield in Monterey County
was the earthquake's epicenter, not Fort Tejon.
The rupture began northwest of Parkfield and traveled approximately
360 kilometers southeast along the San Andreas Fault.
Fort Tejon, the rupture's midpoint, experienced more damage
than other sparsely inhabited Southern California locations.
The 1857 Fort Tejon earthquake was larger than
the 1872 Owens Valley quake and similar to the 1906
San Francisco earthquake.
Scientists analyze the fault to understand its behavior
and prepare for the next earthquake.
