What If A Mega Earthquake Hit California

What If A Mega Earthquake Hit California


Catastrophic earthquake scenarios have played out on the
silver screen for decades, terrifying viewers with quakes
that can collapse skyscrapers or topple entire cities. Here’s what will happen if the
big one hits the West Coast. On July 4, 2019, Ridgecrest, California, was hit with a 6.4 magnitude earthquake and then a 7.1 just one day later. But neither of these compare
to the long-awaited big one, which scientists predict will eventually rattle the golden coast. But when it hits, what will
that actually look like? Here’s what experts say could happen in the seconds, hours, and
days after the big one. While experts can’t know
exactly when a quake will occur, they have a pretty good idea of where. California is located in
a hot zone of fault lines, the most notorious of them
the San Andreas Fault. John Vidale: You know, here
in California you have dangers from a number of different
kinds of earthquakes. The major danger is from the earthquakes on the San Andreas Fault system. Narrator: On average,
the San Andreas Fault ruptures every 150 years. The southern parts of the
fault have remained inactive for over 200 years. Vidale: We haven’t had a big earthquake in Southern California really since 1857. Narrator: In other words, we’re
overdue for a major shake. According to a 2008 federal report, the most likely scenario
is a 7.8 magnitude quake that would rupture a 200-mile stretch along the southernmost part of the fault. Vidale: It’s basically moving
the ground several yards over an area of 50 square miles. So the power of a magnitude 7.8 earthquake is probably close to the power used in the whole state for a year. Basically something that
we as a civilization have trouble creating, short
of, like, a nuclear explosion. Narrator: If you are near the
epicenter of the earthquake, it will be nearly impossible to stand. Vidale: People have this
idea of running out of bed, out of their buildings,
and that’s a terrible idea, because a lot of what we
see in earthquakes is people with broken legs and people
who’ve run through glass. The best thing to do, like we always say, is duck, cover, and hold. Get under some piece of furniture. The main point is to
protect your head and chest. Narrator: During and immediately
following the shaking, buildings could collapse. John Wallace: The number of
buildings that were constructed before about 1980 is really significant, and most of these buildings are very vulnerable to
damage and collapse. Narrator: In this time-lapse video, you can see how building
components would hold up in a high-magnitude earthquake. Wallace: ‘Cause the San
Andreas will produce the kind of long-period shaking which would be very damaging
to very tall buildings, say, in downtown LA, and Century City, and Long Beach, and so forth. Older steel buildings,
the connections in them have not necessarily been designed to withstand the maximum forces that actually can be generated. Narrator: Unreinforced
structures are the least stable, but even buildings up
to code could crumble. John Stewart: The building code, with its minimum requirements, does
not ensure that the building will be serviceable after an earthquake. It’s intended to not kill anybody. There’s a sense that if
it’s modern, code-designed, it’s earthquake-proof and
everything should be great, but that’s not the reality. Narrator: Five steel high-rises could collapse completely, while 10 others will be red-tagged, or unsafe to enter. And, no, the quake would
not cause a tsunami, despite what movies
would have you believe. Vidale: To trigger a tsunami,
it takes an earthquake that moves the ocean floor, and most of the San Andreas is on land, so there would be a little
bit of waves generated from a San Andreas earthquake, but nothing that would be dangerous. Narrator: The quake could
kill about 1,800 people and leave 50,000 or more with injuries. While people could die from falling debris and collapsed structures, the highest death toll
would be from fires. Vidale: Historically, they biggest hazard from earthquakes has been fire. In the 1906 earthquake there
were 3,000 or 4,000 people who were just caught in that wave of fire that swept through the city. Narrator: The aftermath of the big one will wreak havoc on
infrastructure and the economy. Scott Brandenberg: Below our
streets and our buildings is this really complicated
network of infrastructure that could be damaged,
and a lot of the things we take for granted every day won’t be available anymore, right? Like water, electricity, being able to drive
where you need to drive. Narrator: Parts of the San Andreas Fault intersect with 39 gas and oil pipelines. This could rupture
high-pressure gas lines, releasing gas into the air and igniting potentially
deadly explosions. Stewart: So, if you have
natural-gas lines that rupture, that’s how you can get
fire and explosions. Narrator: And after the fires burn out, one of the biggest concerns
in a major earthquake is access to fresh water. The major aqueduct networks that pump water into Southern California all cross the San Andreas Fault and could be seriously damaged. Stewart: So we would be
without the lifelines that bring in imported
water to the region. They cross through tunnels, cross through aqueducts near the surface. All of these would be ruptured, and so we would be losing
60% of our water supply. Many of these distribution lines for water are near sewer lines,
which would also be broken, so now you have a situation
where contaminants are potentially getting
into the water supply. Narrator: Experts say you should keep at least a two-week supply
of water in your home. As the ground shakes and sediments shift, there will be landslides
throughout Ventura and Western Los Angeles County. Brandenberg: There could
be thousands of landslides. There have been earthquakes
that have produced thousands. Landslides definitely can cause
fatalities, property damage. We have a lot of people who
live up in the hills. Right? So that’s the location
where you would be likely to see landslides affecting people. Narrator: And finally, the big one will severely impact the economy. Major transportation networks,
like highways and railways, could be unusable for
weeks and even months. Brandenberg: Some bridges
may not be passable after an earthquake. We’ve had bridges collapse
during past earthquakes. Stewart: You might start seeing key industries leave, population loss, and this could have, you know, devastating long-term
impacts for the region. Narrator: The estimated financial cost of the big one is a whopping $200 billion, with $33 billion in building damages and $50 billion in lost economic activity. This all sounds pretty
bad, but keep in mind that this is based off
of a worst-case scenario. The true impact of a major earthquake is based on a range of unknowable factors. Also, smaller earthquakes on faults directly beneath major population centers are a serious concern. Vidale: But the worst-case earthquakes are hard to predict. You know, that earthquake
in Japan in 2011, their cost almost entirely came because their nuclear
power plant melted down. It’s very hard to
predict what’s gonna fail in a big earthquake. Narrator: So, how can Californians prepare for the big one? Brandenberg: Really have a plan in place. You know, where are you going to meet? What are you going to do? Have water ready. I have a 55-gallon drum full of water. There’s some chemical additive I put in it so it’s potable for five years. Fifty-five gallons is the
right amount for my… I have a family of four. That’ll last us for two weeks. Canned food. You know, you have to be ready. I would say it’s best just to plan to stay sort of where you are. Getting out of LA is bad enough without an earthquake, right? Traffic’s already terrible. If roads are closed and people
are all trying to leave, it’s gonna really be bad.

A mega earthquake will improve Nancy Pelosi's District in L.A. Currently, there are 60,000 homeless American citizens, living in tents, trash, excrement, and typhus on the streets

The trifling state would fall into the ocean and save the USA about 5.6 billion a year in hand-outs to non working free loaders and illegals.

Well if a big enough one hits San Francisco and an ensuing tsunami hit “ the city “ at least all the feces will be washed out of the streets .
Newtons third law of motion .

Hopefully when it does they are having the National Democratic anual mandatory gathering when the entire State slips into the ocean. Maybe we should all fill up our gas tanks this weekend and just drive around on a Global scale in an attempt to completely melt the polar ice caps causing the sea level to rise maybe we’ll get lucky in a few months as a result. Heck it’s worth trying I’m all for Global warming if it will benefit us to finally annihilate this once beautiful State……

i'll send my ex wife there and earthquake will hit…. because where ever she goes all hell breaks loose….tornados… earthquakes… and floods just seem to follow her…. fortunately I survived all of that crap while I was with her lying ass

If California crumbles, that's when the red Dawn invasion will likely begin ….The methane bubbling is a precursor to volcanic activity firing up, so what happens when the PRESSURED NATURAL GAS FRACKING WELLS IGNITE?, Safety procedure, in case of danger put your head between your legs and kiss your arse GOODBYE!!, Yep….

If a earthquake hits California we are not allowed to help. That would require the other states to help a state that hates us.

No problem, California doesn't care how many are homeless. Surely, a earthquake wouldn't dare shake a sanctuary city.

I dont understand why all the clips from movies where the cities are beyond apocalyptic. Yet the experts make it seem like it isn't like that. Sure there is damage to gas lines, sewers, aqueducts, but it isn't like the entire ground will collapse with giant gas fireballs, buildings crumbling and falling over each other and giant tsumani only the Rock and speed boat his way over.

It's God's will to conclude such tragedy! We must all repent! What I truly do not understand why construction isn't made accordingly to protect such from earthquakes, tornados etc. Always be prepared for whatever may come our way. Seems like everyone is accustomed to modern technology: teach our generations to come on how to survive the worse! Always be prepared! Teach your children well, the value of money, ethics, morals etc…

Guess I’m staying in Nj where um…. nothing happens lol give or take a hurricane or two… but nothing happens

Glad my country has no Earthquakes, no Hurricanes, and with an shallow sea highly unlikely we get an Tsunami unless a big meteor decided to land just there.

This is NOT the "big one" that we should worry about. Although a 7.8 magnitude quake is very strong, the Cascadia subduction zone which stretches from the northern tip of California up to Vancouver is the "big one" to worry about. Geologic records show that it has produced 9.0+ magnitude quakes in the past AND big tsunamis.

Been hearing this since 70s. Now they have more people. Think Pelosi wants. Few more million more people to live there.

Actually when the big one comes I hope it makes California break away from the rest of the U.S. Carlitos a toxic state anyway.

California deserves to get destroyed to start over from liberals keeping to destroy it turning it into Central America corrupted government.

Ezekiel 38

17“ ‘This is what the Sovereign Lord says: You are the one I spoke of in former days by my servants the prophets of Israel. At that time they prophesied for years that I would bring you against them. 18This is what will happen in that day: When Gog attacks the land of Israel, my hot anger will be aroused, declares the Sovereign Lord. 19In my zeal and fiery wrath I declare that at that time there shall be a great earthquake in the land of Israel. 20The fish in the sea, the birds in the sky, the beasts of the field, every creature that moves along the ground, and all the people on the face of the earth will tremble at my presence. The mountains will be overturned, the cliffs will crumble and every wall will fall to the ground. 21I will summon a sword against Gog on all my mountains, declares the Sovereign Lord. Every man’s sword will be against his brother. 22I will execute judgment on him with plague and bloodshed; I will pour down torrents of rain, hailstones and burning sulfur on him and on his troops and on the many nations with him. 23And so I will show my greatness and my holiness, and I will make myself known in the sight of many nations. Then they will know that I am the Lord.’

Yes the earthquake may cause an tsunami if its near a mountain and ocean. If an earthquake happens then half of the mountain will break of and drop on to land or water if it lands on water then it will create a wave the more pressure the more bigger the wave is i hope i made sense

Denial.
Amazing how people really believe that a quake that big will never happen.
Many month's before Mt. St. Helens erupted, I was in Seattle and told a dear friend of mine that it was going to erupt within a year. She laughed so hard that she took me around to her associates and told them what I had said. They all found it to be very funny.
It erupted coincidentally a few months later,… on my birthday!
Denial,… human nature at work.
Did I mention the asteroids headed toward earth? Oh, of course. That too will never happen.

I have this bag that you can put dirty water into and leave it in the sun. The heat of the sun distills the water so that you can get potable water any time you can find water. The bag I have is made by a company called Solar Solutions. In my opinion, it's better than saving water and simultaneously hoping you have saved enough water and that the water isn't disgusting when you actually need it. This bag lets you clean the water you can find when you need it. Then all you have to do is note where you have a place that water is always flowing. For us, there's a creek nearby. Yes, it contains a lot of runoff from irrigation, but this bag distills the water which means it boils the water and condenses it into pure water. There are also filter bottles you can buy that will filter the water but obviously there would be a limit on how much water could be safely filtered. When you distill water, you are only getting water out.

The San Ondreas?? I spoke with a guy from the USGS back in the early 90's who was out checking seismometers and he said there was at least 22 feet of slip built up in the southern section of the San Andreas fault line.

You don't know what's going to happen experts don't know what it's going to happen just like nobody knows what happens when after you die I know you would probably enjoy seeing California destroyed I guess you can make some videos about it because as we all know Millennial it's all about subscriptions likes him hits it's not about nothing else voice text

Lol I live in Northridge. And if anybody is familiar with what Northridge and earthquakes and the year 1994 have in common, you can see why I’d be nervous hehehehhahahahahehahaheheheuehueheheueheuehehorohohohhohhhhhhhh
