So, since 2000, the world has been hit with more than 1,700 earthquakes with magnitude
0:09
Many happened around the ring of fire, located around the Pacific Ocean.
0:13
In North America, the biggest threat is the San Andreas Faudlone, which can create an
0:18
earthquake of a magnitude higher than any other, earning it the spine tingling nickname, the
0:24
The potential destruction of California is a terrifying prospect that could have unimaginable
0:29
consequences, but the Big One is just the beginning of what's to come.
0:36
Bad news, scientists have predicted an Earth-shattering event that will occur in 2030.
0:42
Like it or not, there's a 70% chance that will experience the Big One, and it will be
0:47
an earthquake with a magnitude of 6.7.
0:50
The San Andreas Faudlone will cause the Big One, but what is scary is that we can't predict
0:56
On the other hand, a massive earthquake occurs every 100 years.
1:00
This means there's always time to prepare for a natural disaster.
1:04
If we traveled back in time, we'd see a few significant earthquakes like the ones that
1:09
wiped out San Francisco and fought to home.
1:12
Buildings made a long time ago are not quake proof, they will collapse.
1:16
Even if they survive, you should not enter them.
1:19
But, buildings are not the most dangerous part.
1:22
You should watch out for electrical lines and gas pipes.
1:26
Your hillhouse might be lovely, but it is extremely unsafe.
1:30
During quakes, the hill can turn into a massive landslide that will destroy everything in
1:36
Say goodbye to road trips because all the roads will be ruined.
1:39
You should have some spare water and food since you won't be able to go to the supermarket.
1:44
This disaster won't be cheap.
1:46
It will cost the US around $200 billion to recover from the quake.
1:51
At least, the earthquake will not trigger tsunamis, but there's something it can cause
1:55
more damage than the big one.
1:59
The notorious Cascadia subduction zones, starting California, and ends up all the way in Vancouver
2:07
The San Andreas fault line is nothing compared to this zone.
2:09
It can wipe the whole coast off the face of the Earth, an example of hyperbole.
2:15
Subduction zones are tectonic plates forced to be one under the other and constantly pulling
2:21
Zones like these are not to be messed with since they are terrifying hot spots for earthquake
2:30
activity and extremely dangerous because they cause massive underwater quakes.
2:35
But they are underwater, so what can they do to us?
2:39
Well, they can cause giant tsunamis, flooding cities, and destroying the coastline.
2:44
Right now, the most active zone is the Ring of Fire.
2:47
The Cascadia zone might be less active, but it is like a sleeping beast that can wake
2:52
up and destroy everything in his path, causing a ground-breaking earthquake.
2:57
The last time all this stress was released was in the year 1700.
3:03
Unlike the San Andreas quake, this one will cause massive tsunamis and much bigger shocks.
3:08
Let's hope you'll be camping in an open field at that time, because most buildings and
3:13
bridges will likely be destroyed.
3:15
Also, be ready for the aftershocks, as they'll be devastating.
3:19
Nature won't be spared either.
3:20
Landslides will change animals' habitats, even our homes will be changed forever.
3:26
Luckily, there is a light at the end of the tunnel, and scientists are doing everything
3:30
they can to ensure our safety.
3:32
New rules are implemented.
3:34
Every new building must be able to withstand massive shocks.
3:37
They're developing modern warning systems, and every new infrastructure must follow strict
3:42
quick-proof guidelines.
3:45
The one to Fuca and the North American plates are locked together, but they won't stay
3:51
When they unlock, get ready for a massive shake.
3:54
The closer you are to the epicenter, the more damage you'll experience.
3:58
But even if you are lucky to be far away, you may still feel the ground shaking for some time.
4:06
Now, if we compare the Cascadia subduction zone and the San Andreas fault,
4:11
we'll see how much more dangerous the Cascadia zone is.
4:14
In 1994, there was an enormous 6.7 magnitude earthquake in the North Ridge area,
4:20
close to the San Andreas fault.
4:22
Sadly, many people didn't make it, and some were injured.
4:26
Back then, buildings were not strong and earthquake-proof, and many of them were damaged.
4:31
The Cascadia subduction zone can potentially cause a magnitude 9 earthquake.
4:36
A magnitude 6 earthquake has the power of around 44 million pounds of dynamite,
4:41
but a magnitude 9 has the power of 44 trillion pounds of dynamite.
4:48
The strongest ever recorded quake was in Chile.
4:51
Its magnitude measured 9.5, and it destroyed most everything.
4:56
So, let's say you've survived the quake, but the struggle is far from over.
5:00
Soon after, a massive tsunami will strike with waves that might reach up to 100 feet in some areas,
5:06
that someone like the San Andreas earthquake, which can't produce any significant waves.
5:11
So, say goodbye to your beautiful garden, since saltwater will destroy trees and plants,
5:16
changing the environment for a period of time.
5:19
The only positive thing will be you won't need Halloween decorations,
5:23
because all those dried out trees will resemble a ghost forest.
5:27
The combination of waves, quakes, and the sheer size of the area will make this natural disaster
5:33
much more dangerous than any caused by the San Andreas fault, or the so-called big one.
5:38
A quake similar to this happened around 300 years ago.
5:44
Many more have been recorded in the past 3,500 years,
5:48
proving that they continually occur every four to six hundred years.
5:52
So, technically, we have around a hundred to three hundred years before the next big one hits.
5:58
We still have no idea how exactly the Cascadia Subduction Zone works,
6:03
because we discovered it in 1970.
6:06
This zone is super scary because it can cause bigger earthquakes.
6:10
It was found by accident when researchers studied the Ring of Fire.
6:14
They wanted to know if this area had caused any trouble in the past years,
6:18
and the proof was under their noses.
6:21
In Washington, there is a horror for us where nothing has been growing for years.
6:25
When researchers tested the soil, they found a tremendous amount of salt.
6:30
They put two and two together and concluded that a massive tsunami had been the reason.
6:35
Experts still didn't know when the forest was destroyed,
6:38
but Japan kept records of a gigantic earthquake that had a similar effect.
6:44
It was the one that happened in the year 1700.
6:47
There is a one in three chance that the next one will occur in 2050.
6:53
You must know how to survive the Canadian earthquakes and make it out unscathed,
6:57
so listen carefully.
6:59
Those who live in this area have almost no experience with earthquakes like this one.
7:03
Surviving the quake is relatively easy, but the tsunami coming afterward is the real danger.
7:09
After the shake, find the highest ground and go there.
7:13
Only bring the essentials like food and water.
7:15
Yeah, leave your baseball car collection at home.
7:18
After the first hit, don't try to go down.
7:21
seismologists say that most likely, there will be a few more waves and they have proven this.
7:26
On the 22nd of May, 1960, seismologists Jerry Eston and his four friends went to Hawaii
7:33
to see an expected tsunami that was to happen around midnight.
7:36
They set up their gear on Wailuku Bridge with an escape route planned.
7:40
This bridge had been destroyed in the previous tsunami,
7:43
but the new one was much taller and better.
7:46
After midnight, the water was four feet above the average level.
7:50
The second wave hit a half hour after midnight,
7:52
and the water rose another nine feet by 1 a.m.
7:56
The water started going down and dropped by seven feet,
7:59
but the horror was far from over.
8:02
Next, they saw a wave that was around 20 feet tall.
8:05
This shows us that tsunamis are unpredictable,
8:08
and we should listen to experts to stay safe.
8:15
That's it for today.
