9.0 Cascadia Mega-Quake (SIMULATED)
HTML-код
- Опубликовано: 4 ноя 2023
- Case-Study: A potential 9.0 earthquake on the Cascadia megathrust would generate long-period seismic waves and a rolling type of ground motion to major metropolitan areas such as Seattle and Portland. The earthquake will last between 4 to 6 minutes, and it will rupture the tectonic oceanic crust for about 650 miles (1000km). The earthquake will be felt on the whole West Coast of the United States, from Los Angeles to British Columbia in Canada.
The last Cascadian megathrust earthquake occurred in 1700 and the average period of recurrence is about 500 years. According to some new studies, the southern part of the fault may experience magnitude 8 earthquakes every 300 years.
-------------------------------------------
I hope these simulations will bring more earthquake awareness around the world and educate the general public about potential earthquake related hazards. I do also hope that my videos will inspire a future generation of amazing architects, engineers and scientists!

Welcome to the world’s largest and only 3D earthquake simulation channel on RUclips! My channel focuses on realistic 3D earthquake simulations of a variety of virtual structures and types of buildings from around the world. Some of my work has been featured by various international media news outlets and it has also been used by other large RUclips channels such as GeologyHub, GeoPop and CaSeismograph for educational purposes. This channel’s content has also been featured on the Curiosity Channel in a recent documentary called “Breakthrough: Forecasting the Big One”.
The simulations that I post serve an educational purpose and should be solely treated as such. We should not forget that earthquakes are real world events that can sometimes lead to loss of properties and lives.
The simulations were created in Blender 3D with the bullet constraints builder add-on by Kai Kostack.

Very realistic with it getting stronger and stronger and the magnitude going up the longer the quake lasts. I have heard in the past that the intensity of the shaking using does not increase much beyond 7.5 which is shown here and maxing out as it gets closer to magnitude 8. Megathrust quakes are by far the worst quakes in my eyes, along with most other thrust faults including Northridge (which was a blind thrust fault) and tend to damage small to mid size structures badly. You put your heart and soul into this work, and I have the utmost respect for you for this, and I can promise your subscribers will continue to climb until you are in the millions, and for excellent reason too. I still think that when this channel gets big enough, I am hoping you get into a well-paid and rewarding career working for the City of LA, and advising officials with these hypothetical models, that could have a part in the future of you changing things for the better in long term and making ALL buildings safer in CA. This talent can be put to incredible use for the better to change things from top to bottom, along with continuing to WAKE PEOPLE UP to these dangers and lead them to being more prepared!
Quakes like this Cascadia quake with long period shaking are the biggest tests for the very tall buildings. A lot of the newer large towers in Seattle will likely hold up to the shaking including Colombia Seafirst Center which they built properly in mind to handle this, and especially the Space Needle which was massively retrofitted at the time of construction, and then recently it was retrofitted even more to withstand up to a 9.2 magnitude quake. I think it was only the last 35-40 years that they understood the danger of this fault and how large of a quake this could create, and I don't think they put as much of an emphasis on the older towers in Seattle and Portland as they have in areas like Los Angeles and San Francisco. A quake like this is much larger than what the San Andreas could give off, though at up to a possible 8.3 on the strike-slip fault it would still be a hell of a ride also with long period rolling motion mostly side to side like what the Landers, and the later Hector Mine quake created. I would trust most buildings in Downtown LA including the US Bank tower which is massively reinforced in every direction, and the newer Wilshire Grand with the 4' thick core walls built similar to what they did for the WTC (same construction company as well) along with all the other design features to minimize the shocks. Other buildings like the black twin 52 floor towers (used to be known as Arco Towers) I would be nervous to be in because of the older method where they used welds that were brittle (and they broke during the Sylmar quake during construction), though a famous structural engineering firm took up residence in one of the buildings so its likely that they wont come down. The Aeon building as well was built using this method, so only time will tell when the inevitable happens. The other newer buildings should hold up fine as well in my eyes, and many of the older buildings built earlier in the century would probably be ok because many of them were overbuilt at the time. Going back to the Arco towers, I think its horrific they fixed the broken welds using the same method and continued building the up the same way. On a side note, I think that most homes and apartment buildings would hold up to the long period shaking of the San Andreas quake better than the shaking from the Northridge quake, or especially the Puente Hills fault if worst case happens with it maxing at 7.5 and being a thrust fault running directly under DTLA and then extending to West LA and Beverly Hills, where it ends, and that quake would cause likely a lot more destruction in the LA Area than the San Andreas fault rupturing at the south end and spreading up the fault all the way likely to Fort Tejon or further.
One thing that really angered me is the spectacle surrounding the millennium tower in which they did not dig all the way down to bedrock, and THEN switched from steel to much heavier concrete. I don't trust this one bit with it continuing to lean and I believe its one big quake from coming down and possibly crashing into the newer larger buildings surrounding them including Salesforce tower, which was definitely built properly. I believe that there is a chance of a quake happening and the tower coming down during all the bickering between the city and the developers and there will be hell to pay if that happens. I truly believe there were some corrupt people in City Congress that looked the other way after being bribed.
I would LOVE to see you do a model of a theoretical quake like the one during the late 80's during the world series, using the Millennium tower as it currently stands, and then an example of how it would have (more likely not) handled a 1906 scenario on the San Andreas fault with Mercalli intensity rated around 11 in areas with unstable ground, which the millennium tower was built on. And yet the structure still won awards for design and how resilient it is and would be in quakes, but with a shitty foundation, I think that is all out the window. The best thing they can do is get the rest of the tenants to move and take the building down safely while they still have a chance. If that building were to collapse in a daytime quake, the death toll could be easily in the 10k range in that small area alone! Even though the southern portion is loaded with more stress and most likely able to create a larger quake than what could happen in SF, I think Southern Cali would fair better. They have potential death toll estimates up to 1800 people even at magnitude 8 to 8.3 max, and I know that wouldn't be the case in SF which is likely able to put out a 7.8 to 7.9.
It would be AWESOME to see a San Andreas worst case scenario with the US Bank, and the Wilshire Grand, and with City Hall after they redid the foundation and installed base isolation. IF you are interested in doing a video on that it would be great. I got a hold of the construction diagram of US Bank tower, and I was blown away with the reinforcements at every angle.. They REALLY did not fuck around at all with that place, and I am certain it was overbuilt if anything and would hold up even in a larger quake than 8.3. If I was in a large building like that in a massive quake I would feel safe there, even at the top of the building, and this also would be the case for the Wilshire Grand.
If money was not the prime factor in everything, then base isolation should be used with ALL big buildings along with Hospitals and Schools. And with more use the cost will drop and eventually all apartments and homes could go this route?
Sorry for the long posts - I type VERY fast and this took less than 2 mins, so before people try to bash me for this, try keeping this tidbit in mind.. I do this because I love your videos, and I am deeply into this same sort of thing you are. I am a systems engineer for a VERY large company everyone knows of and also run my own business, and I was originally getting into structural engineering but decided not to due to the 10 years of school to do this, and I was able to learn everything on my own in the IT world starting in the 9-10th grade and not going to college. But still I have the same engineering mindset as the mindset tends to apply across the board, and this stuff fascinates the hell out of me and is also horrifying at the same time. I live in La Crescenta, and found my neighborhood is on VERY solid ground and in the foothills most of the top dirt washed down in storms over the past 100+ years, leaving a situation where there is VERY solid rock not far down, which is the best place to be in a quake with proper foundation, and the shaking is MUCH less intense on bedrock. On sand in the Marina area where I lived in the past and my family has property, the shaking is much more intense even with a proper foundation dug deep, and it also shakes longer as well.
Yes
Uhm, okay 💀
that’s crazy
Portland is absolutely doomed. Most buildings downtown will go down for sure in an earthquake like this... I suspect bridges won't fare well either. I hope I'm wrong.
The crane over there managed to withstand the earthquake.
Crane: Earthquake not strong enough 😈
I love your videos EarthquakeSim! Their just oddly satisfying, it also shows how much care you should put on earthquake awarness!
Thank you so much!! You can call me Michael 😁
@@EarthquakeSimodd question but mind making an earthquake simulation for Phoenix Arizona, the city where I live? Maybe a large dust storm kicked up by the shaking?
I watched your videos before and after the Moroccan Earthquake, and listening to the sounds, give flashbacks, and for the steps at the end, no one was prepared everybody got out of the houses, how could they hide under a table…
Good video! one thing i don't like is how the power didn't go out, the power plane and power lines would have been destroyed
Yep but then... There wouldn't be anything to see in the simulation... And I wanted to show the duration of the quake 🙂
@@EarthquakeSim ok!
This is the most detailed yet, good job.
This is prolly your best video for me. Coz just like earthquakes in real life it started slow then as it progresses it builds up. Nice!
I love this channel! It is so cool!
Same!!!
thank you so much for being so valuable in this community! Let's promote more earthquake awareness together :)
@@zane1403 thank you so much Zane!
I'm amazed the crane and the canopy over the pump area held up so well. Also that the underground gas tanks didn't explode and catch fire. But well done.
thank you so much friend! :)
@@EarthquakeSim Okay, I got one for you: ON May 22, 1960, the (so far) only 9.5 earthquake hit Chile, with a ginormous tsunami. Can you do a sim of what that would look like today?
1.05 the block flipping is cool. Makes you wonder if anything like this happens in real life.
Its amazingly shocking how much damage can be done in so short a duration.
Four minutes would be a long time if you were really there.
@@bruceb2804 Thank you for the link. This is the "best" example of ground movement I have seen.
Damn! That was apocalyptic! This shows how scary earthquakes can be!
That deep rumbling though... woaaah.
If you need some ideas on what to do next, here is a list:
- amusement park
- aquarium
- city park
- subway station and tunnels
- elevated metro
- aerial tramway/gondola
- seawall with city
- car dealership
- water treatment plant
- stadium
- indoor swimming pool
- outdoor festival
- santa's house 🤣
Put earthquakes on the naughty list! Do Santa's house!
earthquack: "exist"
Random explosion at 1:16 out of the screen: "explode"
Can you simulate the 9.6 Chile earthquake? and if possible the 6.8 earthquake in Azerbaijan?
This is for sure one of if not my favorite video yet because of for realistic it feels! Great job!
@@Ifromfridaynightfunk yep :)
thank you so much for saying this! I've been putting a lot of hard work for all of you:)
Dude, get the pga on screen as well. Magnitude no use unless we know the distance from it. But I love the video ❤
You always satisfy us! Love this Channel ❤
thank you so much for always being here!!!
Didn't take me long to get hooked onto this channel! Love the effort into this video!
@@EarthquakeSim I wonder if you’ve been asked this already but what would happen if a 10.0, earthquake happened across the west coast of North America? I would think that aside from the complete and utter devastation of all major cities from the quake itself, there would inevitably be a tsunami from such a powerful earthquake and probably a big one too. I would think that one possible event would be that if it managed to agitate activity out of some of the cascade volcanoes that are particularly active like Mount Saint Helens or otherwise potentially dangerous like Mount Hood, or Mount Rainier. At the very least there could be the concern of avalanches and significant rock falls from those volcanoes from the earthquake. To add insult to injury it is entirely possible that some areas might suffer from wildfires caused by ruptured gas lines in some areas away from the coast that weren’t affected by the tsunami. Do you think that might be a potential outcome to such a hypothetical event?
Soy chileno y recuerdo el terremoto del año 2010 en chile a menudo cuando veo videos de este tipo, siempre se me vienen los recuerdos.
Este es un video bastante real en su forma de mostrar el sacudimiento del suelo y su destrucción, como también desde el momento en que inició hasta que finalizó. Lo que no a simulado con certeza es el movimiento superficial del suelo, yo recuerdo que la intensidad en la localidad en donde yo vivía en ese momento fue muy fuerte... El movimiento del suelo era impresionante y el ruido que tampoco lo simula con exactitud, porque estamos hablando de un terremoto grado 9.0. El terremoto del 2010 en chile se caracterizó por ese ruido ensordecedor qué no dejaba de tumbar los oídos, como si el cielo se fuera partir por los relámpagos qué no paraban de formarse y la tierra de fuera abrir en grandes grietas debido al ruido tan espantoso qué todos los chilenos qué estuvimos en ese momento lo recordamos.
Actualmente se que la aceleración sísmica del sector en el que yo vivía fue de 0.54g osea estuvo situada en VIII mercalli, creame que las ondas superficiales del suelo hicieron qué el suelo se sacudiera similar a como lo muestra usted entre los minutos 02:30 y 03:30. Mi mamá me cuenta que ella cuando iba subiendo al segundo piso de la casa donde estaba durmiendo yo, paso por el patio y cuenta como el suelo fluctuaba igual como cuando alguien sacude la sabana de su cama. Si logrará similar eso yo le doy un 10, porque el nivel de destrucción más que en la aceleración esta en las ondas superficiales y no en la intensidad., los efectos de un sismo a mi parecer aveces tienen más y aveces menos ondas superficiales, y creame que la intensidad de cada uno sin importar si es grado 6.0 o 5.0, varía mucho aunque se situe en V o VI.
Im always satisfied me and i learned new things about earthquakes ❤ anyways what was that orange glow?
It was an explosion 🙂
Can you do a simulation of the Japan 2011 earthquake for the upcoming 13th anniversary of that disaster?
that would actually be a great idea!!!!!!! I will make it!
Here from another video you responded to Me in :D
(I haven't watched the video yet I will edit this once I do)
Ok i found out theres more than 1 gas station videos, also the lights blinking is the realistic part that i wanted, ty 😄 (altho i suggested it after it happened)
Wow! The canopy over the gas pumps stayed up the whole time
its sad to see that this simulation ended very fast 😭😭
im was expecting it for more than 6 min@@Ifromfridaynightfunk
Whelp the Seattle city are now reduce to rubble
A marked improvement
Dawg that is crazy, a 4:18 long earthquake
Thank you for the video
Yay new video
start doing more of this earthquake
i can literally feel the vibrations in my ears through the headphones
The cars:calm dancing
Those sounds seem real
I'm glad I have chosen them well!!
I’m from cascadia 😨
wow. That petrol station roof is more flexible than me. 🤣
Pls 17 august 1999 İzmit and 12 nowember 1999 düzce earthquake simulation can you do it? 😊
I have the seismic data. I could make a simulation soon!
@@EarthquakeSim thank you :)))
The scariest place to be will be the coast. As Alice Isn't Dead put it: "If you're standing on the beach, Even if you start running the moment the dogs start barking, you don't have enough time to escape."
Everythong should just be made out of cranes 😂
Can we see one with NYC?
Yes
@@EarthquakeSim Yay! Thank you! I feel very honored that you responded to me ☺️
Imagine a earthquake that last 5 minutes tho 🤯🤯
Unfortunately such large earth quakes can last that long. The 2004 Sumatra earthquake lasted 10 minutes.
@@bensmall6548That earthquake lasted THAT LONG?!?! 😳
@@GracemarieJohnson2763 Yes it did last that long. Mega thrust quakes which is what they’re called, can last for several minutes
Hiiii!
hello! thanks for being here with us!
now imagine using unreal with it
Oh, good! As someone who lives within spitting distance of the Cascadia subduction zone, I guess it's time to give myself some nightmare fuel. In reality, though, if you live in the PNW, you just sort of exist in a perpetual fatalistic state, lol.
Why no vertical movement? Not accurate.
I have vertical movements in my other simulations. This was impossible to achieve because of some software limitations if the earthquake is longer than 1 minute... 🙃😁
@@EarthquakeSim I love it the Cascadia Subduction Zone. While it's only 10-30% likely to occur in my lifetime, I'm trying to do whatever I can to be in the best position possible for myself and my house. Like seismic retrofitting/etc. And there is virtually zero complete and accurate info out there., very frustrating to have to piece-meal it all together.
I WANT THIS GAME
The good thing about this earthquake is that you can take your time to leave the building
Imagine if this was a game
Name Game?
I'm the only one playing this game. It's a 3D software Blender ❤️
😮😮😮😮😮😮
Looks like, first, you have to survive the earthquake, and then 10 minutes to 15, here comes the tsunami! A terrible.,terrible, Catastophic event, when this happens! Last Cascadian 9.0 earthquake, happened in 1700 A. D. Personally, I would move elsewhere as soon as possible. Same goes for those in Southern California, which is also overdue, for a very large quake! There have been several prophecies about these earthquakes coming soon! Look up Sadhu Sundar Salvarej's messages on 3 large earthquakes coming to the U.S. Cascadia, southern California, and the New Madrid fault line, down the center of the U.S.
海外には、耐震基準が無いので、被害大絶亡ですが、我が国、日本国は、耐震基準震度6強以上に、耐える建築に、法律で、定めているので、大丈夫。建築物が大破しても、人命を守る優先が基本ですから。
You definitely want to be a tree in this situation..
Actually, above 9.0 are called “Superquakes” so this type of magnitude is a Super Earthquake
