Uhh...did you forget about the Millennium Tower? It's sinking into landfill, leaning and cracking. That's directly next to the SalesForce Tower!!
A building falling into another building won't make it collapse, since the buildings are mostly full of air. At worst it would just lean on Salesforce Tower, assuming it collapses in that direction.
@@jamaalfridge For a tower the size of Millennium Tower, it wouldn't lean on the Salesforce Tower. The buildings are so far apart that if the tower ever managed to be so far from the vertical position that it is actually in contact with the Salesforce Tower then the columns in the Millennium Tower would buckle because the tower would be somewhere on the order of greater than 20 degrees from the vertical and that kind of lean would crush the columns near the base. Therefore it is almost certain that the Millennium Tower would collapse either way in this scenario, the only difference would be whether or not the collapse of the Millennium Tower would cause the collapse of the Saleforce Tower which I can't say for sure whether that would happen or not.
It is number one on my list.
Even the buildings in San Francisco aren’t straight
That's because the piles did not originally touch bedrock while being built on landfill
"We're not ready to have 10s of thousands of people with no home to go to." Ah. But but you already do. Ironically though, they are probably safer in tents than Oakland's unretrofitted buildings.
In 1989 earthquake, my Palo Alto office was a disaster. However, my Belmont home was literally untouched (one candle stick on top of bookshelf moved). The house, which is up on a hill overlooking SF Bay, is 1) on bedrock and 2) has 20 foot metals piles into that bedrock. Sadly, not too many homes posses those two critical features.
Henry Hernandez a 9.0 has only been record 5 times and never in California.
Another possibility is a tsunami hitting California that is sourced from subduction quake (between Japan and Philippines)
If that occurs, we wouldn't even feel the quake, but would have a little forewarning of the incoming tsunami.
It would be hell of traffic trying to find high enough ground though.
The most safe peoples are 10K homeless. In SF you can pay 1M for a tiny studio and die in it bc of earthquake. I love this city
Wild Earth I hated it and glad I moved out after 10 years (08- January 2018)
Just Another Important Person Where you moved ?
Actually a studio in San Francisco is about 100,000
Kevin 1986 still insane prices
The Salesforce tower foundation it's not good I work there doing core drilling in the concrete piers and it was just sand coming out we couldn't get any solid concrete core
California cali It looked like a giant air filter to me, until I watched this video. Now, it looks like the Titanic.
Wow that’s interesting feedback. Scary...
Typical right...I wonder who got paid lots of $$$ to look the otherway like they did on that other POS tower... Also funny you would think with a comment like this the news outlets would be interested in chatting with you...
Well it’s still standing and will be just fine.
What do you do if the bed rock cracks??? Earthquakes also easily cracks bed rocks too as we learned in the past
Ligma
Tuning the buildings resonate frequency. Tesla is so happy
I have a feeling the Salesforce Tower may have to come down. But if that happens, contractors will have to carefully do the task, floor by floor. That's bound to be time consuming.
While we might not be sure if our buildings will fall or not in the next earthquake, I'm willing to be PG&E never bothered to repair the gas pipes under those homes and we get San Bruno x1000.
That guy would choose to be in that building? I like his confidence but I recall there was quite a bit of confidence in the Titanic too. I'd choose to be in a park in an open field preferably in a helicopter and taking off.
im so glad the local government is doing something about the big one, i wish manila would do the same
Why is this whole comment section so pissed off
People don't like reality checks. Especially when they have been putting on blinders for years...
Great report…I recall the earthquake and the retro fits that we all had to make…that’s why it’s so surprising to me that the CITY approved plans for Millenial tower which isn’t bolted on bedrock. People who aren’t true San Franciscans don’t realize that the beach during the gold rush era went inland to Powell street/ market! That Montgomery street had docks for ships…
Salesforce is Titanic of buildings 😅
If that's the case then it's doomed cause Titanic sunked on it's first voyage.
Salesforce Tower is safe.
Not sure about Millenium tower.
Isn’t the whilshire grand taller than the sales force tower
It is
Tallest building in California but if you go by roof height then Salesforce Tower is taller
Salesforce Tower is taller by roof height .. wilshire Grand is taller by its 294 foot spire. The building itself is shorter than Salesforce Tower.
“I’m there’s an earthquake I’m coming to the Salesforce tower”. - Yeah boy, you will have time for that. 🤨
@1:22 lol dude has no idea what he's talking about. It's the steel rebar that makes salesforce strong against ground movements, not just concrete. Concrete is terrible against lateral loads, which is what an earthquake creates.
What about bridges to
He just said a lot of the buildings they are looking at are 300 feet tall. Yet the ones in the video are over 500 feet
Ah🙂 The Salesforce Tower. 🏢🏙🌁
Who can give me a link where explains the steel structure to support the houses (retrofit) I am from Turkey, we have same story here..
Japan has made codes strong enough, it's just about long-term thinking and not listening to builders who don't want slightly higher up front costs. We will end up paying when all those buildings have to be rebuilt. If you give strong retrofit incentives (and mandatory ones for larger buildings) plus a code that actually makes sure the building is usable after, you save money in the end. Whether that's 10, 20 or 50 years away does not matter.
California will probably end up having a code like that, after its economy is in shambles.
7:10 it's about saving lives lady...
Hahaha me after hearing her thought process: 🤦♀️
funny that now that salesforce building is leaning without an earthquake
The tower is.not secured into bedrock and that is why it’s leaning.
it's called SALE with conviction because it good for you
2:21 this video is gonna get demonetized
i cant be the only one laughing at this?
How?
Can we get a documentary for LA, Chicago and NYC?
Wouldn't the ground just break and shift with enough force from an earthquake (Big enough) to dislodge those anchors?.
Hi people. how are r you? This is just a suggestion ok? Today's houses and buildings almost don't have happy colors anymore, and the colors they use today are some depressing, or irritating colors, they don't bring joy and they don't make the environment happy or lighter. They only use gray, black ored cream color now. These colors in excess of depression or irritate people. They could use more cheerful colors in the painting, just like in the old days. More cheerful colors, a light orange, peach, yellow, red or other green, blue. If they painted those colors it would be great. The bars too, coulded paint white, or blue, green, orange, not just black or gray. The colors above that I narrated last, peach, orange, yellow, red bring joy and so I think people will be encouraged to have a little more joy. The peach color for me is the one that stimulates me the most. Mainly or much more the warm colors. And this also refers to everything or other areas as well that paint things, such as appliance manufacturers, among others. That now also do everything just in those colors of black, gray and white, there's no more color. A hug.
And not everyone is like that and we can't generalize, okay? But most of these builders of huge buildings, skyscrapers, they ruined and still are sometimes like this, several neighborhoods, among them the old and calmer ones. From São Paulo and several other places. It left them chaotic and full of people from so many skyscraper buildings that they raised. They don't just build 1 or 2 buildings. They raise 10, 15 and some all close to each other and in the same neighborhoods. And as soon as an opportunity arises, they build another building, and so on. May God enlighten the minds of these people, theirs and give them judgment and common sense, to have balance in what they do. Because their excess of greed that they have and the excess love for their money is too much, to the point of destroying the quality of life in the neighborhoods because of the money. The directors of this construction company should be like that and are responsible for these things. I hope that one day, all that will change! And things will improve definitively and forever in God's new world! These huge buildings spoil the streets, the sun doesn't shine on the streets anymore, they don't even have ventilation anymore, the air stays still, and sometimes there's no air, people don't take the sun anymore, they get a lack of vitamin D in the body and with problems with health, you can't look at the blue sky and relax anymore, you just see these horrible giant buildings, the landscape is spoiled and the sidewalk, they leave it uneven and crooked and you can't walk on the sidewalk anymore, you have to walk on the edges of the street which are straighter, in the middle of the cars. In addition, the streets are full of people and they have no structure for the high flow of people and cars that are around these buildings, which are built in inappropriate places, which are not suitable for buildings of this stature. Then there is no more calm and peaceful place to walk and relax, and people recover from the problems with these buildings. People will no longer be able to stay calm, they will all be stressed about it or angry. This is not evolution, it's the opposite, it's regression. They will no longer have quality of life. Hugs. ^
I live 3 blocks from the Salesforce tower. Definitely getting crushed during an earthquake
NOTHING CAN'T. STOP. NATURE....
That's a double negative ;)
Building is tuned. Resonance away from earth. Sounds like pyramids .
Im Glad My House Is Not Too Tall Its Just Medium Size I Hope It Wont Fall Down
So let's talk about 10 story concrete buildings in Istanbul collapsing at any moment for no fucking reason, rather than 2 story wooden structures in which I would lay my ass in a moment of an earthquake in Cal.
It looks like a concrete and glass Sequoia tree. It has very deep bedrock loving roots (piles), a very thick trunk (utility core), lots of branches (floor), and foliage (curtain wall). It's going to take an ultra powerful earthquake to uproot or snap this tree at the trunk
"You need to be thinking: what have you done to make your house safer?"
So its the job of the people buying houses to make sure their buildings are earthquake-safe and not the people construction them then?
Anslee Smith it’s for the older buildings
@@daniel.n460 Still, it seems weird to me that the mandatory cost of retrofitting homes would fall on the homeowners and not the city/county.
Absolutely: people are not willing to pay to live in safer homes. No matter if they are renters, landlords, or if they are building a new home.
Even the idea of getting earthquake insurance is non-sense to so many Californians. They say it's "too expensive". It's normal that it is expensive, since the risk is so high...
What about the Christchurch earthquake? 185 people died, with people left with no homes because of liquefaction
Okay. Is something about the happen cause why does the news keep bringing up earthquakes!? If it happens it happens, we just need to be ready damn. They just need to make California more safe.
Low-quality videos disgraceful!
the last thing you need in an earthquake is a stiff concrete building with a stiff concrete core support, during a mega quake, concrete shatters, in places like Japan they have shock absorbing mechanisms in the base for this purpose to minimize shaking of the structure, a stiff core concrete core allows the vibration to go throughout the building!
Nope. You're wrong. There are a lot of concrete frame buildings with shear walls that come through earthquakes with flying colors. Take a look at the Northridge Earthquake in 1994. Lots of concrete buildings with no damage.
@@kansasthunderman1 keep believing in indestructible buildings!
I believe they are giving you a sense of safety, but inside they know that it has never been tested, they have no clue how it’s actually going to behave when the big one hits. Everything is theoretical. Sadly, I believe when the big one hits, we will see how many lies we have been served by these building experts. That is, the few that survives.
They have been tested.....Viscous Dampers work !! Buildings with Viscous Dampers did not get damaged in the 7.6 Mexico earthquake.
The weak buildings will fall ....the strong ones will remain standing.
1:50 the construction characteristics he's about to describe are reflective of those applied to a much greater degree at the World Trade Center in New York City. Does he expect us to believe that mechanical and architectural characteristics that failed so swiftly and spectacularly on September 11th will be more effective during an earthquake? Yeah, right
At least we won't have to worry about being hit when it does collapse, since it will no doubt do so faster than the speed of gravity, and neatly into its own foot print. Hey, it worked for 7 WTC, why not here?!
...The difference there is that the World Trade Center had massive holes in its strongest part (the steel outer tube) and it was burning for hours. Steel loses almost half its strength in uncontrolled fires burning for prolonged periods of time. The potential energy the nearly three decade old building had stored was immense, and all that being immediately converted into kinetic energy on the lower half as soon as the upper half began to move provided almost no resistance. The lower floor just disintegrated under the pressure, and the building’s downward momentum grew stronger the more it collapsed.
Earthquakes are different from plane crashes and fires.

The leaning Millennium Tower quit the chatroom
Im just staying the fuck away from sf until hit happens
The wiseman built his house upon the rocks! Shit that's really old and good advice! Too bad current engineers are too stupid to know this= Millennium Tower!
Well I live in a trailer park and live in a trailer home built in 1969 AND live literally on top of the San Andreas in San Bernardino sooo.... I’m fucked 😂😂
*1:Twin Towers*
But when the big one comes
If CA has a massive earthquake tomorrow displacing thousands of people from their homes....we should ship em’ out to other countries as refugees.
Nope
All new building built by china will come down. The chinese built bay bridge will be one of those structures.
fernarias the bay bridge was made years ago... if your talking about the old one
@@Evili555 Yes, and it was made by chinese contractors with chinese labor and chinese materials. Chinese quality construction will collapse during an earthquake as they do in china. Sometimes they don't need an earthquake, see australia's buildings that are being evacuated due to safety concerns.
fernarias well aren’t the Chinese known for making high quality buildings in a quick amount of time
You got that right. I used to work in the elevator business and there are 100s of concrete high rises that don;t have adequate shear walls.If there's something wrong with the building, the elevators are the first mechanical system to get collateral damage.
Hope it happens soon....greedy landlords are making everything too unreachable....
EARTHQUAKES ARE FOUND IN THE BIBLE MATTHEW 24: 6,7
ROARING WAVES
LUKE 21:25-28
When these buildings fall the architects will simply say it was stressed beyond expected loads so tough!
Like a weather man, can't really say what's really true!
Japans expensive levee walls didn't help them at all.
The Japanese nuke plants were designed by General Electric and they are the same as in America.
So we'll do all of this again tomorrow !
Wyatt Earp the building isn’t going to fall.
The kind of news I like to see 😂
And now I will try to type a sentence with my nose
tiy aew fay
I dont care how glorified they make California to be.. I could never in my life live there and go to bed at night KNOWING a 7.0 earthquake could happen at anytime.... I’m happily staying in Oklahoma City where we know When and where a Tornado will develop 😂
Look up New Madrid Zone... you are just as screwed, if not more so.
Moore, Oklahoma has been destroyed twice in the last 20 years. Just saying it could've been a few miles north. A big SF earthquake happens once a generation at most.
Fracking companies are causing earthquakes in Oklahovma
Ever heard of the New Madrid Fault?
Oklahoma is also earthquake country as well
Hopefully all of them
I wish it was all the Trump towers across the globe.
At least the earthquake will obliterate UC Berkeley, so it won't be all bad
I hope the big one doesn’t happen because then we will get even more leftists from California moving to Texas..
Trust me, none of us want to live in Texas.
There are far more people from the other states coming to CA than Californians moving out.
DoctorWeeTodd lol you’re all delusional.. they’re all coming here.. including businesses
Brandy Y. If California secedes from the Union today it immediately becomes the 5th largest economy in the world. The USA will lose 13% of all federal taxes. Over 2/3rd of all of the USA’s fruits and nuts, and over 1/3rd of all the USA’s vegetables becomes foreign imports. Because that comes from California. You also lose the leader in communications, technology, and the internet. And the entertainment industry.
While your small town or City of Austin is getting an influx of middle class Californians who expatriated because of wanting a simpler quieter life away from high living costs due and the hustle and bustle of gentrification and massive development, the San Francisco Bay Area and Silicon Valley has seen a flood of transplants. Many of them come for the gold rush in the tech sectors and are paid the highest wages. Starry eyed people come to bring their dreams alive in Hollywood or the games industry. Others come to receive the social services because they are in the most desperate situations. (Many are actually sent directly here by Southwest states such as Texas (And especially Nevada and Arizona) because of lack of services.)
You Californians in this section are all stupid the only growth you're getting is illegals hoping the border. Californians are all over Austin and the ones at fault for car accidents. Can't drive over 70 without crashing.
