In this video, we delve into the geological and seismic history of the San Andreas Fault, a 800-mile fault line responsible for some of California’s most devastating earthquakes. We'll explore the recent discoveries that suggest the fault may soon crack, potentially triggering catastrophic events. Scientists are warning that the southern section of the fault is "locked, loaded, and ready to go," raising concerns of a magnitude 8.0 earthquake. We’ll also look into how these quakes could cause immense damage, including the possibility of a massive tsunami. Learn about the vulnerable cities, the efforts in earthquake preparedness, and the historical context behind the San Andreas’ seismic activity. Join us as we uncover what could be one of the biggest natural disasters in U.S. history.
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 sutan
sea in the South to the north for 800
mil through Coastal and Inland
California the fault is known for
cutting California in half and causing
devastating earthquakes that keep the US
government and Californians on edge
recent discovery 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 Dev 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 5
years after a minor earthquake in 1989
one of the San andreas' bigger secondary
faults erupted in the Los 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 re station Frasier Park
Daily City Desert Hot Springs Gorman San
Bernardino Wrightwood Palmdale and
Bodega Bay are vulnerable every C foran
was worried when Southern California
earthquake Center Director Thomas Jordan
warned of the San Andreas faults
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 MI 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 seisman
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
Andrea's fault the Pacific Plate slowly
moves Northwest relative to the North
American Plate at this significant
tectonic border this action should ease
16 ft 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 Kon pass has not
shifted since an earthquake in 1812 from
1680 to 1690 Southeast towards the salt
and 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
plan 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 the
San Andreas fault breaks according to
the USGS a magnitude 7.8 earthquake on
the southern San Andreas Vault 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 2 minutes the San Gabriel
Valley and East Los Angeles where
sediments trap shaking waves may
experience in significant shaking the
sewer system might be down for 6 months
causing 1500 deaths to prepare for the
worst this situation is critical
strengthening Los Angeles's dangerous
Aqueduct and telecommunication systems
is another priority California must act
quickly to reduce the damage and deaths
from a major tragedy the 1857 Forte hon
Quake shows that the San Andreas fault
May wreak massive devastation
this 7.9 magnitude earthquake which
started in montere county and moved
South past Fort tahon to the Kon pass in
San Bernardino County gained its name
soil liquefaction and tree uprooting in
Stockton occurred during the one to
3-minute Tremor despite running through
Los Angeles the San Andreas vault is 30
Mi 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 F Quake to show the
devastation from the sutan 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 Vault 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 false
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 cm per year
while geologic time has seen 1 cm per
year with such activity the next big one
is imminent the 1906 San Andreas fault
earthquake caused some portions to move
6.4 M 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 anovi side
as they slide past each other the fault
does this making the rift's geology and
landforms complicated and unpredictable
despite its risk tecton 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 Andrea's fault is more than an
undetectable crack in Earth's crust it's
visible in portions of California visit
the cizo plane in San Louis abiso County
to see this powerful fault Marin County
has the faults scarps and pressure
ridges some areas of the fault are
hidden by brush and alivium or haven't
moved in years in cities like Los
Angeles and San Bernardino roadways cut
through mountains of fine bowdery
crushed rock from moving plates the San
Andreas fault is a 30 milliony Old
geological
Masterpiece rocks from different places
have been driven together by plate
movement M and collision generating a
diversified rock type on both sides of
the fault the selenian block of granite
in central Northern California came from
Southern California and the Nino
volcanoes in Los Angeles County are the
other half of a volcanic complex that
begins 200 Mi 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 Andrea's fault while
substantial at 880 Mi 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 1,000m fault in Chile the biggest
earth earthquake ever recorded was
9.5 predicting earthquakes is another
fallacy scientists are working hard to
forcast 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 mega Quake 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
faults 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 roots for family vacations
camping bird watching and rock
collection like beads in a thread State
and national parks along the fault offer
breathtaking views of wild flowers 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 18574 ton earthquake or the 1906 San
Francisco earthquake the San Francisco
earthquake leveled structures and killed
hundreds the great Fort tahon earthquake
felt through Southern California was the
largest Parkfield in montere County was
the earthquake's epicenter not Fort
tahon the rupture began Northwest of
Parkfield and traveled approximately 360
km Southeast along the San Andreas Vault
Fort ton the ruptures midpoint
experienced more damage than other
sparsely inhabited Southern California
locations the 1857 for ton 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 what are
